What Happens to Your Chevy's Cooling System in 100-Degree Texas Heat

TL;DR

Triple-digit Texas heat makes both your Chevy's engine cooling system and air conditioning system work harder, especially in stop-and-go traffic. Watch for a temperature gauge running hotter than normal, coolant leaks or odors, reduced AC performance, or other changes from how your vehicle normally operates. Catching a cooling or AC problem early can help prevent an uncomfortable drive from becoming an overheating or breakdown issue.

Dallas doesn't do mild summers. When temperatures stay in the triple digits, your Chevy's engine cooling system and air conditioning system both have to manage more heat, especially during stop-and-go traffic, long drives, and extended periods of idling.

Most drivers notice an AC problem quickly. A cooling system problem can be easier to miss until the temperature gauge starts climbing or another warning sign appears. Here's what high Texas temperatures mean for both systems, the signs that something may be wrong, and when it's worth having your Chevy checked.

How 100-Degree Heat Stresses Your Chevy's Cooling System

Your Chevy's engine cooling system works by carrying heat away from the engine through the coolant and releasing that heat through the radiator. When the outside air is already 100 degrees or hotter, there's less temperature difference between the hot cooling system and the surrounding air, which makes shedding that heat more demanding.

Stop-and-go traffic can make those conditions even tougher. At highway speeds, outside air naturally moves through the front of the vehicle. At low speeds or while idling, the cooling fans play a bigger role in moving air through the radiator and AC condenser. A low coolant level, restricted airflow, or a fan that isn't working properly may therefore become more noticeable during a long summer commute.

Your AC is dealing with the same hot outside conditions from a different system. The AC condenser, typically located near the front of the vehicle ahead of the radiator, has to release heat from the refrigerant before the system can effectively cool the cabin. That's one reason AC performance problems can become especially noticeable during extreme heat or extended idling.

Signs Your Chevy's Cooling or AC System Needs Attention

Changes from how your Chevy normally operates are often the first clue that something needs attention. Watch for:

  • The temperature gauge running hotter than normal, especially during traffic or extended idling.
  • An engine temperature or overheating warning appearing on the instrument panel.
  • A sweet or unusual odor inside or around the vehicle, which can be a sign of leaking coolant.
  • Fluid underneath the vehicle after it's been parked, particularly if it's accompanied by a low-coolant warning or rising engine temperature.
  • AC that isn't cooling as well as it normally does, especially if the change is sudden or continues after the vehicle has been running for several minutes.

A change in AC performance doesn't automatically mean there's a problem with the engine cooling system, but either system is worth checking when its normal behavior changes. If your Chevy displays an overheating warning or the temperature gauge moves into the hot range, don't continue driving and hope it cools down. Follow the guidance in your owner's manual and have the vehicle inspected before continuing to drive.

What Kind of Coolant Does Your Chevy Use

Many Chevrolet vehicles use GM-approved DEX-COOL coolant, but the correct coolant and service interval depend on your specific model and model year. The safest place to check is your Chevy's owner's manual or the coolant specification listed for your vehicle.

Don't rely on coolant color alone. Different coolant products can look similar, and color doesn't tell you whether a product meets the specification your Chevy requires. If the coolant level is low, avoid topping it off with whatever happens to be available unless you've confirmed it's compatible with your vehicle.

In extreme Texas heat, the coolant condition matters as much as the radiator and fans around it. Low coolant, contamination, or a leak can reduce the cooling system's ability to manage engine temperature. If you're repeatedly adding coolant or notice the level dropping again after a top-off, have the system inspected rather than continuing to refill it.

What's Involved in a Chevy AC and Cooling System Check

Diagnosing weak AC or an engine cooling problem starts with identifying the symptoms rather than simply adding refrigerant or coolant. Depending on what your Chevy is doing, a technician may check refrigerant pressure and look for leaks, inspect AC components such as the compressor and condenser, check cabin airflow and the cabin air filter, and test related electrical components.

Engine cooling concerns call for a different set of checks. That may include inspecting coolant level and condition, looking for leaks, checking the radiator and hoses, and confirming that the cooling fans and other components are operating properly.

Refrigerant type also depends on the vehicle. Newer Chevrolet models may use R-1234yf, while older vehicles may use R-134a. The correct refrigerant and service procedure should always be determined by the specifications for your Chevy's model and model year.

Why Cooling System Problems Matter More in Texas Heat

Triple-digit temperatures don't cause every cooling system problem, but they can make an existing weakness more noticeable. Low coolant, a leak, restricted airflow, or a component that isn't working properly gives the cooling system less room to manage engine temperature when outside temperatures are already high.

That's why a temperature gauge running hotter than normal or an overheating warning isn't something to put off during a Texas summer. Continuing to drive an overheating vehicle can cause serious engine damage and turn a cooling system problem into a much larger repair.

That's also why Jupiter Chevrolet builds flexibility into how customers get service handled during the hottest months. Vehicles that need to stay overnight or longer can use the dealership's loaner and shuttle options, so a cooling system repair doesn't mean going without a vehicle in the middle of a Dallas summer.

What to Do If Your Chevy's AC Stops Working on a 100-Degree Day

Start by paying attention to what's changed. If airflow from the vents has become noticeably weaker, a dirty cabin air filter or another airflow restriction may be part of the problem. If airflow still feels strong but the air isn't getting cold, the AC system itself may need diagnosis.

AC performance can change for several reasons, including refrigerant leaks, electrical problems, or issues with components such as the compressor or condenser. Rather than guessing at the cause or adding refrigerant without knowing why the system is low, have the AC system checked if the problem continues.

One important distinction: warm AC isn't the same as an overheating engine. If your AC stops cooling but the engine temperature remains normal and there are no temperature warnings, that's generally an AC concern. If the temperature gauge climbs into the hot range or an overheating warning appears, follow your owner's manual guidance and stop driving when it's safe to do so.

Jupiter Chevrolet also offers an overnight drop-off option for customers who need to leave a vehicle outside regular service hours. Contact the service department for current drop-off instructions and to schedule your AC or cooling-system diagnosis.

How to Protect Your Chevy Before the Next Heat Wave

A few simple habits can help you spot problems before the next stretch of triple-digit temperatures. Check your coolant level according to the instructions in your Chevy's owner's manual, and only check or add coolant when the vehicle is cool enough to do so safely. If the coolant level keeps dropping or you notice fluid under the vehicle, have the system inspected rather than repeatedly topping it off.

Pay attention to how your Chevy normally behaves, too. A temperature gauge that begins running higher than usual, a new warning message, an unusual odor, or AC performance that suddenly changes can all be reasons to schedule a closer look.

For cabin comfort, parking in a garage or shade when possible can reduce how hot the interior gets while the vehicle is sitting. If the cabin has been baking in direct sun, letting some of that trapped hot air escape before asking the AC to cool the interior can also make the first few minutes of the drive more comfortable.

Preventive habits won't fix an existing mechanical problem. If your Chevy is overheating, losing coolant, or showing another persistent warning sign, have the cause diagnosed rather than trying to manage the symptoms through the rest of the summer.

Frequently Asked Questions

What should I do if my Chevy starts overheating?

If the temperature gauge moves into the hot range or an overheating warning appears, don't ignore it or continue driving in hopes that the temperature will come back down. Follow the instructions in your Chevy's owner's manual and stop driving when it's safe to do so. Continuing to operate an overheating engine can cause serious damage.

Why does my Chevy's AC blow warm air in extreme heat?

Warm AC can have several causes, including low refrigerant from a leak, electrical problems, or an issue with the compressor or condenser. If the problem continues after the vehicle has been running for several minutes, the AC system may need to be diagnosed rather than simply topped off with refrigerant.

Does warm AC mean my Chevy is overheating?

Not necessarily. Your Chevy's air conditioning system and engine cooling system perform different jobs, so weak or warm AC by itself doesn't mean the engine is overheating. Watch the temperature gauge and instrument-panel warnings separately. If the engine temperature rises into the hot range or an overheating warning appears, treat that as an engine cooling issue and follow the guidance in your owner's manual.

What refrigerant does my Chevy use?

Refrigerant type depends on your Chevrolet's model and model year. Newer vehicles may use R-1234yf, while older vehicles may use R-134a. Check the specifications for your vehicle before adding or servicing refrigerant.

How often should I have my Chevy's cooling system checked in Texas?

Follow the maintenance schedule for your specific Chevrolet model and model year. Have the system checked sooner if you notice the engine running hotter than normal, a coolant warning, a possible leak, or another change in how the cooling system is operating.

Why is the airflow from my Chevy's AC weaker than usual?

A dirty cabin air filter can restrict airflow through the vents, but weak airflow can have other causes as well. If replacing or inspecting the filter doesn't resolve the problem, the HVAC system may need a closer look.

Does Jupiter Chevrolet offer overnight drop-off for AC or cooling system service?

Yes. Jupiter Chevrolet offers an overnight drop-off option for customers who need to leave a vehicle outside regular service hours. Contact the service department for current drop-off instructions and appointment information.

Is a 2026 Chevy Still a Good Buy Now That the 2027s Are Arriving?

TL;DR It depends on the model, but for most of the lineup, yes. The Tahoe, Suburban, Traverse and all-wheel-drive Equinox change very little for 2027, and there's no reported 2027 gas Blazer. The Silverado 1500 is fully redesigned and the Colorado gains 40 horsepower, so those two deserve a closer look. Qualifying 2026s at Jupiter get the same Jupiter Advantage benefits. Every fall, the same thing happens. The new model year starts showing up, and people who were ready to buy start wondering if they should wait. It's a fair question. Nobody wants to drive home in what feels like last year's model. Here's the honest answer, model by model. For Most Chevy Models, How Different Is the 2027? For most of the Chevy lineup, a 2026 is still a good buy even with the 2027s arriving. The biggest exceptions are the Silverado 1500, which gets a full redesign, and the Colorado, which gains 40 horsepower. Front-wheel-drive Equinox models also get an 8-speed automatic for 2027, and the Trax is expected to receive a styling refresh. For the Tahoe, Suburban and Traverse, the changes are more limited, while all-wheel-drive Equinox models already use the 8-speed automatic. So before deciding that a 2027 is automatically worth waiting for, look at what actually changed on the Chevrolet you're shopping. That's what we'll break down next. What Changes for 2027, Model by Model? Here's what Chevrolet and published industry reporting show for the 2027 model year, as of October 2026. What changes for 2027 Chevrolet models, and what it means if you are shopping a 2026 Model What changes for 2027 How big is the change? What does it mean if you're shopping now? Equinox Front-wheel-drive models move from a CVT to an 8-speed automatic. New color and camera-related equipment changes are also expected. Small to moderate If you want a front-wheel-drive Equinox with the 8-speed, the 2027 is worth a look. AWD models already use it. Trax Early reporting and undisguised prototypes point to refreshed front and rear styling and an updated interior. Full 2027 details have not yet been officially announced by Chevrolet. Moderate, mostly styling If having the refreshed look matters to you, waiting may make sense. Otherwise, compare the 2026 against the 2027 once Chevrolet releases the full details. Traverse Two new colors, new wheels and an interior camera. Industry reporting also points to a shortened 2027 production run ahead of a refreshed 2028. Small There isn't a major redesign for 2027. The bigger change is expected for 2028. Colorado The updated 2.7L TurboMax increases output from 310 to 350 horsepower, along with an increase in torque. Three new colors and 5G Wi-Fi capability are also reported for 2027. Moderate The extra 40 horsepower is a legitimate reason to compare the 2027 closely with a 2026, especially if performance matters to you. Tahoe and Suburban New White Sands paint, package changes and standard heated and ventilated front seats on RST models. Small If those particular changes don't matter to you, there isn't a major redesign separating the 2026 and 2027. Both are built at GM's Arlington Assembly plant here in North Texas. Blazer (gas) Industry reporting says Chevrolet will skip the 2027 model year for the gas Blazer, with a refreshed 2028 expected afterward. No 2027 gas model If you're shopping for a new gas Blazer, the 2026 is the current model rather than the outgoing version of a vehicle being replaced by a 2027. Silverado 1500 Full redesign with new V8 engines, larger standard screens and a revised trim lineup. Major This is the model where waiting for the 2027 deserves a much closer look. We'll break it down next. The pattern is pretty clear: the decision isn't simply 2026 versus 2027 across the entire Chevrolet lineup. On several models, the changes are relatively limited. On others, a specific update may matter to you. And with the Silverado 1500, the differences are substantial enough to warrant their own discussion. The Biggest 2027 Change Is the Redesigned Silverado 1500 The 2027 Silverado 1500 is a full redesign, so this is one model where waiting deserves a closer look. Chevrolet revealed the next-generation truck in June 2026 and says it is expected to reach dealerships near the end of 2026. The biggest changes include: New V8 engines. The next-generation Silverado introduces new 5.7L and 6.6L V8 engines in place of the current 5.3L and 6.2L V8s. The 2.7L TurboMax is updated, while the 3.0L Duramax diesel continues. Larger screens. Every trim gets a standard 16.3-inch center display and 12.2-inch driver display. A new trim lineup. The lineup becomes Work Truck, Custom, Custom Trail Boss, Silverado, Trail Boss, ZR2 and High Country. The familiar LT, RST and LTZ names go away. So why would you still consider a 2026 Silverado? You prefer the current V8s. If you've driven the 5.3L or 6.2L V8 and that's the powertrain you want, the 2026 gives you that option. You want one of the current trims. If you've been shopping an LT, RST or LTZ, those trim names don't continue into the redesigned lineup. You need a truck now. The 2026 is available now, while the redesigned 2027 is expected to begin reaching dealerships near the end of 2026. On the other hand, if the new V8s, larger screens or redesigned truck are what you really want, waiting for the 2027 makes sense. That's exactly why this isn't a blanket "buy the 2026" recommendation. "If price is a major concern, the 2026 is always the best choice. Unless a major body change occurred between years, the majority of the rebates and dealer discounts will be heavily weighted towards the sell down of current model years. It's traditionally where your biggest savings will be. If price is not an issue, my opinion will always favor towards a new model year." Eric Fussell, General Manager, Jupiter Chevrolet What Does a 2026 From Jupiter Chevrolet Come With? Choosing a 2026 instead of waiting for a 2027 doesn't mean giving up Jupiter's ownership benefits. Qualifying new 2026 vehicles receive the same Jupiter Advantage benefits as qualifying new 2027 vehicles. That includes: Lifetime Powertrain Warranty on qualifying new vehicles at no additional cost. To keep the warranty active, required maintenance must be completed at Jupiter Chevrolet in Garland within every 5,000-mile interval. Complimentary recall, tire and alignment checks with every service visit. Loaner vehicles during qualifying service visits, subject to availability. Collision deductible reimbursement on qualifying claims repaired at Jupiter Collision Center. Appearance protection for qualifying repairs including door dings, wheel repair, interior repair and windshield repair. You also have Jupiter Chevrolet's service department on I-635 in Garland for maintenance and repairs after the sale. See the Jupiter Advantage for complete program details, eligibility requirements, coverage and exclusions. When Does Waiting for the 2027 Actually Make Sense? Waiting makes sense when the 2027 changes something you'll actually use: the redesigned Silverado 1500, the Colorado's extra 40 horsepower, the 8-speed automatic in a front-wheel-drive Equinox or the expected Trax styling refresh. For the Tahoe, Suburban and Traverse, the 2027 changes are limited, and there's no reported 2027 gas Blazer to wait for. If none of the changes on your model matter to you, there's less reason to wait solely for the newer model year. What Happens to 2026 Inventory as the 2027s Arrive? As 2027 models begin arriving, the selection of new 2026 vehicles naturally gets smaller. Once production of a model year ends, the remaining 2026 supply is limited to vehicles that have already been built or are still in transit. For example, production of the 2027 Tahoe and Suburban was scheduled to begin at GM's Arlington Assembly plant in September 2026, while production of the 2026 gas Blazer was scheduled to end that same month. That doesn't mean a particular 2026 vehicle is about to disappear, and we won't tell you it is. It does mean that if you have a specific trim, color or option combination in mind, your 2026 selection can narrow as the model-year changeover continues. If you're ready to look, browse Jupiter Chevrolet's new inventory or schedule a test drive. If you're deciding between a 2026 and 2027, ask us to compare the specific models you're considering so you can see whether the newer model year actually gives you something worth waiting for. Browse New Inventory Frequently Asked Questions When do 2027 Chevys arrive at dealerships? 2027 Chevrolets arrive at different times depending on the model. Production of the 2027 Tahoe and Suburban was scheduled to begin at GM's Arlington Assembly plant in September 2026, while Chevrolet says the redesigned 2027 Silverado 1500 is expected to reach dealerships near the end of 2026. Ask Jupiter Chevrolet about expected timing for the specific model you're considering. Is the 2027 Silverado 1500 a redesign? Yes. The 2027 Silverado 1500 is a full redesign with new 5.7L and 6.6L V8 engines, larger standard screens and a revised trim lineup. The 2026 Silverado keeps the familiar 5.3L and 6.2L V8s, so which model year makes more sense depends partly on which powertrain, technology and trim you prefer. Is there a 2027 Chevy Blazer? Not a gas one, based on current industry reporting. Chevrolet is expected to skip the 2027 model year for the gas Blazer, with a refreshed 2028 model reported to follow. That makes the 2026 the current gas Blazer while the Blazer EV continues separately. Does a 2026 model qualify for Jupiter's Lifetime Powertrain Warranty? Yes, qualifying new 2026 vehicles purchased at Jupiter Chevrolet come with the Lifetime Powertrain Warranty at no additional cost, just like qualifying new 2027 vehicles. To keep the warranty active, required maintenance must be completed at Jupiter Chevrolet in Garland within every 5,000-mile interval. Ask the sales team to confirm that a specific vehicle qualifies, and see the written Jupiter Advantage terms for complete coverage and eligibility details. Will buying a 2026 instead of a 2027 affect resale value? It can. Model year is one of several factors that can affect a vehicle's future resale value, along with mileage, condition, equipment and market demand. The actual difference between a 2026 and 2027 will depend on the specific model and the market when you eventually sell or trade it, so we wouldn't assume a specific future value based on model year alone. Should I wait for a 2027 Chevy or buy a 2026? For most models, compare the specific changes before deciding. Waiting deserves a closer look if you want the redesigned 2027 Silverado 1500, the more powerful 2027 Colorado, the 8-speed automatic in a front-wheel-drive 2027 Equinox, or the expected styling changes to the 2027 Trax. For models with more limited changes, a 2026 may give you what you want without waiting for the newer model year. Where can I buy a new 2026 Chevy near Garland, TX?

Who Can Service a Chevy EV in DFW? Inside Jupiter Chevrolet's EV Service in Garland

TL;DR Chevy EVs skip oil changes, spark plugs and engine belts, but tires, brakes, cabin air filters, coolant and software still need attention. High-voltage battery work belongs with EV-trained Chevrolet technicians. Jupiter Chevrolet in Garland is a GM EV-certified service facility and handles Chevy EV diagnosis and battery warranty repairs on site. If you own an Equinox EV, Blazer EV, Silverado EV or Bolt, you've probably noticed the maintenance reminders don't look like they did on your last gas vehicle. No oil changes. No spark plugs. But an EV still has tires, brakes, coolant, a 12-volt battery, software and a high-voltage battery system that may need service over the life of the vehicle. The question is which work can be handled like routine vehicle maintenance and which work needs EV-trained Chevrolet technicians. Here's what a Chevy EV needs, when specialized EV service matters and how EV service works at Jupiter Chevrolet on I-635 in Garland. What Does a Chevy EV Need for Maintenance? A Chevy EV generally has fewer routine maintenance items than a gas vehicle. Chevrolet notes that EV owners can skip maintenance such as oil changes, spark plugs, engine belts and engine air filters. But there are still parts and systems that need regular attention. Here's what stays on the list: Tires. Tire condition, pressure and rotation still matter on an EV. Follow the maintenance schedule for your specific Chevrolet and rotate the tires when recommended. Jupiter also checks tire tread and alignment when vehicles come through the service lane. Brakes. Regenerative braking uses the electric motor to help slow the vehicle, which can reduce use of the friction brakes. The brake system still needs to be inspected and maintained according to Chevrolet's schedule for your vehicle. Cabin air filter and wipers. These are still routine maintenance items on an EV and should be replaced as needed. Coolant and the battery thermal system. Chevy EVs use thermal-management systems to help keep the high-voltage battery within its intended operating range. Coolant inspection and service requirements depend on the vehicle and maintenance schedule. The 12-volt battery. Chevy EVs still have a low-voltage battery that supports vehicle electronics and other systems. Software. Some vehicle software updates can arrive over the air, while others may require a dealership visit, including certain recall-related updates. Your Chevy EV's owner's manual and maintenance schedule are the best guides for the specific intervals that apply to your model and model year. When Does Your Chevy EV Need EV-Trained Chevrolet Technicians? Routine items like tires, wipers and cabin air filters are familiar maintenance. The distinction becomes more important when service involves the high-voltage battery, electric propulsion system or vehicle software and diagnostics. Chevrolet specifically directs owners to EV-trained technicians at a Certified Service Chevrolet dealership for inspection, testing or replacement of the high-voltage battery. Depending on the issue, specialized EV service can include: High-voltage battery service. Inspection, testing or replacement of the high-voltage battery requires EV training, safety procedures and the appropriate diagnostic equipment. Battery and electric propulsion warranty repairs. Warranty coverage depends on the vehicle, component and terms of the applicable Chevrolet warranty. Covered EV repairs may require service through an authorized GM EV service facility. EV system diagnostics. Charging concerns, propulsion warnings and battery-related messages may require GM diagnostic tools and vehicle-specific service information. Software and recall work. Some updates can happen over the air, while others, including certain recall-related work, may require a dealership visit. For basic maintenance, you have more options. When the concern involves the high-voltage battery or another EV-specific system, a Chevrolet dealership with EV-trained technicians has access to the GM service information, diagnostic equipment and training for that work. Who Works on EVs at Jupiter Chevrolet? Chevy EVs are serviced on site at Jupiter Chevrolet in Garland. Jupiter is a GM EV-certified service facility, and its technicians are trained to work on EV systems using the specialized diagnostic equipment, tools and safety procedures that differ from traditional gas vehicles. Jupiter's service department is led by Jason Ashcroft, Fixed Operations Director, who has been at Jupiter for more than nine years and has worked with General Motors products for more than 36 years. For first-time EV owners, Jason says the biggest difference is that EVs generally have fewer routine maintenance items than gas vehicles. There are no engine oil changes or spark plugs, but tires, brakes, suspension, alignment, cabin air filters and cooling systems still need inspection and service. Tire condition and alignment are particularly important because of an EV's weight, torque and performance characteristics. The questions Jupiter's service team hears most often are about battery health, driving range, charging, tires, service intervals and what happens if there is a problem with the high-voltage battery or EV system. As Jason puts it, the maintenance is different, but it doesn't have to be complicated. If a Chevy EV is damaged in a collision, Jupiter Collision Center is on the same campus and can handle EV collision repairs in house, including battery removal and structural repair when required. The Collision Center follows manufacturer-published safety and repair procedures, including high-voltage safety protocols when a repair involves battery isolation, removal or work near high-voltage components. What Happens When You Bring an EV to Jupiter for Service? A Chevy EV service visit at Jupiter starts much like any other service visit, with a few checks that are especially useful on an EV. You drive over the service-lane scanner. Every vehicle that comes in for service, EVs included, passes over Jupiter's drive-over scanner as it enters the service lane. The scanner measures tread depth on each tire and captures 360-degree imagery of the vehicle. Tire, alignment and open-recall results appear on a large monitor in the service lane as you pull in. Your vehicle gets a complimentary multi-point inspection. Jupiter checks items such as tires, brakes and fluids, along with complimentary checks for alignment and open recalls. Jason Ashcroft describes the multi-point inspection as "basically, it's the vehicle's report card." The results are easy to read. The inspection uses green, yellow and red readings to show what looks good, what should be planned for and what needs attention. The same color system appears with the service-lane results, making tire wear or low tread easier to spot. Your service advisor reviews what was found. Your advisor can walk you through the inspection results, explain any recommended service and review the next steps with you before additional work begins. How Does the Chevy EV Battery Warranty Work? Chevrolet's EV battery and electric propulsion limited warranty covers eligible components for 8 years or 100,000 miles, whichever comes first. Coverage depends on the specific vehicle, component and warranty terms, so check the warranty information for your model and model year. If you notice a battery or propulsion warning, charging problem or another concern with the high-voltage system, Jupiter Chevrolet can diagnose the issue on site in Garland. Jupiter is a GM EV-certified service facility, and its EV-trained technicians have the training, diagnostic equipment, tools and safety procedures required to work on EV systems. If the diagnosis identifies a covered high-voltage battery or electric propulsion issue, Jupiter handles the warranty repair on site as well. That means owners can have the vehicle diagnosed and repaired at Jupiter rather than having the battery work sent to another facility. A couple of things worth knowing before you ever need it: Keep your service records. Having your vehicle's maintenance and repair history available can be helpful if a warranty concern comes up. Don't ignore battery or propulsion warnings. If your Chevy EV displays a battery, charging or propulsion warning, schedule service so the issue can be diagnosed. Check your warranty booklet. Coverage details can vary by model and model year, and your warranty information spells out what applies to your specific vehicle. How Do I Book EV Service at Jupiter Chevrolet? Booking EV service at Jupiter works the same way as scheduling other Chevrolet service. You can schedule online or call the service department at 972-464-1093. Service hours are 7:00 AM to 7:00 PM Monday through Friday and 7:00 AM to 4:00 PM Saturday. The service department is closed Sunday. When you schedule, mention that you're bringing in a Chevy EV and describe what you're experiencing, especially if you've seen a warning message, had a charging problem or noticed a change in vehicle performance. That gives the service team more information about the concern before you arrive. If you can't get there during regular service hours, Jupiter also offers 24-hour service drop-off, so you can leave your vehicle and keys after the service department has closed. If you'll need transportation while your EV is being serviced, ask about loaner vehicle availability when you schedule. Loaner vehicles are available for qualifying service visits, subject to availability. Jupiter Chevrolet is located on I-635 in Garland and serves Chevy EV owners throughout Garland and the surrounding DFW area.

Why Buy New at Jupiter Chevrolet? The Warranty, the Pricing and the Shop Behind It

TL;DR Buying a new Chevrolet at Jupiter Chevrolet in Garland, Texas includes Lifetime Powertrain Warranty eligibility on every new Chevrolet except Corvette through the Jupiter Advantage, a walkthrough of dealer-installed accessories and costs before you sign, access to Jupiter's in-house Custom Shop and sales, service, parts and collision support on the same Garland campus. Coverage stays active by completing required maintenance at Jupiter Chevrolet within every 5,000 miles, and carries eligibility requirements worth understanding before you count on it. A 2026 Silverado is a 2026 Silverado. Chevrolet builds it, and the truck sitting on a lot in Garland is the same truck sitting on a lot anywhere else in Dallas-Fort Worth. What changes from one dealership to the next is everything attached to it. What the warranty covers and what keeps it active. What appears on the price besides the price. Who handles the vehicle after you drive it off, and whether that is the same organization that sold it to you. So this is less about the Chevrolet itself and more about what comes with buying one at Jupiter: the warranty, the pricing conversation, the Custom Shop and the people who will still be here to service or repair it after the sale. What Comes With a New Chevy at Jupiter That Does Not Come With the Vehicle Itself The vehicle itself is only part of what you are buying. At Jupiter, there are a few things attached to the purchase that are worth understanding before you sign. Lifetime Powertrain Warranty coverage. Every new Chevrolet purchased from Jupiter is eligible at no additional cost through the Jupiter Advantage, except Corvette models. There are maintenance requirements to keep that coverage active, which we will get into below. A clearer look at the actual price. Dealer-installed accessories can vary from one vehicle to the next. The important part is knowing what is on the specific vehicle you are considering, what it costs and what your total number looks like before you sign. Access to the Custom Shop. Lifts, wheels, tint, bed liners and other upgrades are handled in house, with the Custom Shop on the same Garland campus. Jupiter Advantage ownership benefits. Beyond the powertrain coverage, qualifying vehicles may receive additional benefits including collision deductible reimbursement and wheel-repair protection, subject to the program terms. One address for the rest of it. Sales, service, parts, custom work and Jupiter Collision Center are all on the same Garland campus. The rest of this guide breaks down what those things mean in practice, including the requirements that come with them. Because a benefit is only useful if you understand what you are actually getting and what you have to do to keep it. The Lifetime Powertrain Warranty: What Qualifies and What Keeps It Active Every new Chevrolet purchased from Jupiter Chevrolet is eligible for the Lifetime Powertrain Warranty, with the exception of Corvette models. It comes at no additional cost as part of the Jupiter Advantage and covers major powertrain components such as the engine, transmission, transfer case where equipped and drive axles for as long as you own the vehicle, subject to the terms, conditions, maintenance requirements and exclusions in the written warranty. There is an important difference between receiving the coverage and keeping it active. Required maintenance has to be completed within every 5,000 miles, and that maintenance has to be performed at Jupiter Chevrolet in Garland. Having the same work completed at another GM dealership or an independent repair shop does not satisfy that requirement. That is worth knowing before you buy. If you plan to keep servicing the vehicle at Jupiter, the requirement fits naturally into that ownership routine. If you live farther away, move out of the area or prefer to have maintenance performed somewhere else, it is something to consider before treating the Lifetime Powertrain Warranty as part of the value of the purchase. Coverage is not limited to new vehicles. Qualifying pre-owned vehicles can receive it as well, so the Lifetime Powertrain Warranty by itself is not what separates a new vehicle from a used one at Jupiter. Know What's in the Number Before You Sign The advertised price does not always tell you everything about the specific vehicle you are looking at. Some vehicles at Jupiter may already have dealer-installed accessories such as window tint, a spray-in bed liner or other equipment added on site. Those items can affect the price of that particular vehicle, and what is installed can vary from one unit to the next. The important part is knowing what you are paying for. Before the transaction is finalized, you should be able to see what equipment is on the vehicle, what has been added by the dealership and what those items cost. If you are comparing the same model or trim at more than one dealership, compare the out-the-door numbers, not just the advertised prices. Ask what equipment is already installed on each specific vehicle and what else is included in the final amount. Two trucks with the same trim can end up at different totals because they are not necessarily equipped the same way. When we talk about pricing at Jupiter, the goal is transparency. Some vehicles are priced above the manufacturer's MSRP because they include dealer-installed products. Depending on the vehicle, those may include: Rhino spray-in bedliner. Protects the truck bed from scratches, dents, corrosion and everyday wear. XPEL window tint. Helps reduce heat and UV exposure inside the vehicle and adds privacy. Wheel locks. An added layer of theft protection for the wheels and tires. Vehicle etch. Puts a permanent identification number on designated glass surfaces as a theft deterrent and can help with recovery. LoJack security system. Theft-recovery technology designed to help locate and recover the vehicle if it is stolen. When these products are installed, a vehicle's total selling price may be above MSRP. That difference reflects actual products and equipment added to the vehicle, and you should see each one and what it costs before you sign. Certain products can be removed at your request where applicable, so ask if there is something on a vehicle you do not want. Want It Customized? Start Before You Drive It Home Buying a new truck does not necessarily mean taking it exactly as it came from the factory. Jupiter Custom Shop is on the same Garland campus, so customers interested in changing the stance, wheels, tint, bed protection or other accessories can start that conversation while they are choosing the vehicle rather than figuring it all out later. Some vehicles are already customized before they are listed for sale. For others, the Custom Shop can help customers choose upgrades based on what they want the finished vehicle to look like and how they plan to use it. That becomes especially useful when suspension, wheels, tires and steps all need to work together as part of the same build. You can select upgrades through the Custom Shop as part of your purchase. The work can be completed before delivery, during the delivery process or after you take the vehicle home, depending on what you prefer and the type of upgrade. The Custom Shop handles a wide range of upgrades, including blackout packages, wheels and tires, lift and leveling kits, XPEL window tint, Rhino spray-in bedliners, running boards, bed covers, lighting, appearance packages and other Chevrolet accessories. Because every build is different, timing depends on the upgrades you choose, parts availability and installation requirements. The team reviews your selections and gives you an expected completion timeline before the work begins. The vehicle's Lifetime Powertrain Warranty coverage and the warranties that come with individual aftermarket parts are separate. Qualifying vehicles remain subject to the Jupiter Advantage eligibility and maintenance requirements, while individual Custom Shop products may carry their own manufacturer warranty terms. Thinking about modifying the vehicle somewhere else? Certain aftermarket modifications can affect Lifetime Powertrain Warranty eligibility or coverage. That mainly applies to work on the electrical system, suspension or engine and performance components done by an outside dealership or an independent repair or modification shop. If you are considering a modification, talk with Jupiter before the work is done so the team can help you understand whether it could affect your coverage. Upgrades professionally installed through the Jupiter Custom Shop are handled with the applicable warranty requirements in mind, and the full warranty terms spell out what is covered. What Happens After You Drive Off The purchase is one day. What happens after it is the part you live with for years. Routine service at Jupiter includes a 151-point inspection developed from Chevrolet's 172-point checklist, with items the service team considered outdated or no longer useful removed. Tire rotation is included with every oil change, and alignment checks, tire tread-depth checks and open recall checks are complimentary for vehicles coming through the service department. When the vehicle needs to stay, Jupiter has a fleet of more than 50 loaner vehicles for qualifying visits, along with concierge pickup and delivery across DFW, shuttle service and an overnight drop-off option. And if the vehicle is ever in an accident, Jupiter Collision Center is on the same Garland campus with its own repair team and estimators. That is the larger advantage of having sales, service, parts, custom work and collision repair connected in one place. The people who help you buy the vehicle are part of the same organization responsible for helping you maintain, customize and repair it afterward. What to Bring and What to Expect on the Day You Buy If you are getting ready to purchase, ask the team what documents you will need to complete the transaction. If you are trading a vehicle, having the registration, both keys and any title or payoff information available can help keep the process moving. Then give yourself enough time to go through the numbers before you sign. The contract walkthrough is where you should see what is on the vehicle, what has been added, what each item costs and what your final number looks like. It is also the time to make sure you understand the Lifetime Powertrain Warranty requirements and when your first required maintenance visit will be due. You should leave knowing what you bought, what you paid for and what you need to do next. If you want to get some of the process started before you arrive, Jupiter's credit application and trade valuation tools are available online. New or Used? The Warranty Isn't the Tiebreaker One thing that does not necessarily separate new from used at Jupiter is the Lifetime Powertrain Warranty. Qualifying pre-owned vehicles can receive the coverage too. The differences are elsewhere. A new Chevrolet gives you the full factory warranty from the beginning, the ability to shop for a specific model, trim and configuration, and potentially the opportunity to plan Custom Shop upgrades as part of the purchase process. A pre-owned vehicle gives you a different set of choices based on what is currently available, how it is equipped, its mileage and its price. So if you are deciding between a new and pre-owned Silverado, Tahoe, Traverse or another Chevrolet, do not make the decision based on the words "Lifetime Powertrain Warranty" alone. Look at the specific vehicles, the coverage each one carries, how they are equipped and what the numbers look like for each. Frequently Asked Questions Does Jupiter Chevrolet include a Lifetime Powertrain Warranty on new vehicles? Yes.
