Does Your GMC Need a Radiator Repair?

Does Your GMC Need a Radiator Repair?

The radiator is a crucial component in your GMC's cooling system. Its job is to remove heat from the coolant, so it can cool down the engine. If your radiator isn't working properly, you should get it checked immediately by your GMC dealer. Check out these signs indicating your car needs a radiator repair.

Overheating Engine

Once your radiator stops doing its cooling job efficiently, your engine temperature will start climbing rapidly. If your temperature gauge is in the red zone and the check engine light has come on, your radiator isn't working. Driving with this problem can cause serious engine damage due to the excessive heat. So visit your dealer to have the radiator fixed.

Coolant Leaks Under the Car

If you suspect radiator issues, check the ground underneath the front of your GMC for any colored fluid leaks. These leaks are caused by a cracked radiator or damaged radiator lines. If the coolant levels drop significantly due to the leaks, there won't be enough fluid to absorb heat from the engine. As a result, your vehicle will start to overheat.

Blocked Exterior Radiator Fins

Your radiator has exterior fins that provide the surface area needed by the radiator to dissipate heat from the coolant. As the car moves, air flows over the fins and absorbs heat from the hot coolant. If the fins are clogged with dirt or leaves, there will be restricted airflow and inadequate cooling. You should get the fins cleaned and checked for damage to ensure proper airflow in the system.

Sludge Inside the Radiator

Over years of use, the radiator can corrode, causing rust deposits to accumulate inside. These deposits mix with the coolant and slowly build up as thick sludge inside the radiator. Sludge can clog the interior channels, causing restricted coolant flow. If your radiator is old and has started to rust, you should replace it to keep your coolant clean and effective at cooling the engine.

Bent or Damaged Fins

Radiator fins are soft and delicate and prone to damage by rocks, sticks, and other road debris. If they are bent, smashed, or damaged, they won't allow proper airflow to the coolant. Your dealer's technicians have the right tools to straighten out bent fins and restore airflow. If the fins are severely damaged, you may need to replace the radiator.

Damaged Radiator Hose

The radiator hose allows coolant to cycle from the engine and radiator for cooling and back to the engine to absorb heat. If the hose has visible swelling or spongy spots, it can leak coolant and reduce the efficiency of the cooling system. Replace it before it ruptures and prevents coolant circulation to the engine.

You should address these radiator issues early to protect your engine from severe and costly damage. Contact Oxendale GMC to schedule radiator diagnosis and repair with our GMC-certified technicians.

6 Signs Your GMC Needs a Brake Repair

Certain warning signs will appear when you need a brake repair from your local GMC dealership. The problems are hard to miss, so you'll know when it's time to visit the dealership before the problem goes on for too long and causes major problems with your car. more 1. The ABS Light Is On Cars have a built-in mechanism that tells you when there's something wrong with the braking system. If the ABS light illuminates on the dashboard, then get to the dealer straight away, even if your car isn't showing other signs that there's a problem. 2. The Brakes Make Noise When Used Brakes make squealing or grinding noises when used because they need new brake pads. When the problem isn't bad, you'll hear squealing, like a small piece of metal is scraping against another metal surface. This is a built-in component of the brake pad designed to alert you to the fact that the pads need to be replaced. Over time, more and more of the pad wears away until there's little to no brake pad left. This leaves the rotor and brake caliper to scrape against each other, and they'll damage each other over time. 3. The Rotor Has Grooves It's a good idea to perform visual inspections of various parts of your vehicle every few weeks. This includes your rotors. If you see grooves on them, or they look in any other way abnormal, then get to the dealer. They may need to be turned or replaced. 4. The Brake Pads Look Thin If your brake pads look thin, around 1/4 of an inch thick or less, then visit the dealership. You need 1/4 of an inch of pad minimum to drive safely, and pretty soon, you'll probably start hearing the brake pad wear indicator scratching against your rotors. 5. The Brakes Perform Badly If your brakes aren't responding or if it's taking longer for you to stop when you use the brake pedal, then you need to go to the dealership as soon as possible. Continuing to drive with your brakes and this condition can endanger you and others, especially if the problem gets worse over time. 6. The Brake Pedal Feels Different If your brake pedal feels different while in use, even if the difference is subtle, visit the dealership to get it checked out. It's common for brake issues to make the pedal feel spongy or like there's no resistance when you use it. Most of these problems are pretty simple to fix, and our technicians can tackle them head-on. Come get your braking system repaired at Oxendale GMC in Flagstaff, AZ.

GMC Towing Capabilities: Maintenance for Optimal Performance

Hauling heavy trailers and boats can stress some of your truck's most vital parts, such as the engine, brakes, and transmission. To ensure your truck is always in optimal trailering condition, you need to schedule routine GMC towing maintenance at your GMC dealer. Learn about the key systems that need routine service today. more When it comes to maintenance that supports the towing capabilities of your truck, it's best to start under the hood. A basic oil change can go a long way to enhancing the performance and power of your engine, particularly if you spend a lot of time on the road. Additionally, you will want to keep an eye on other fluid levels in your vehicle, such as differential fluid, transmission fluid, and coolant. Because trailering and towing require a lot of power from your engine to generate the torque necessary to move extra heavy loads, you will need to pay special attention to your cooling system. Depending on your truck, you may have a radiator and external coolers that prevent the engine from overheating, and the coolant for all of these coolers needs to be changed frequently so you get the best performance from your truck. Hitch and Wiring For trailering safety on the road, you should check your hitch and wiring systems any time you use your truck for towing. Taking the time to double-check the tightness of your hitch attachment and the security of your receiver pin can ensure your truck is ready to tow. If your trailer supports an electrical wiring system, be sure to check the connectors and performance of the trailer lights each time you prepare for travel. Tires and Brakes It's essential to have tires with good tread when you are hauling a trailer behind your truck. When your tires have high tread, you have better traction on the road that supports your torque and braking. Brake pads should also be routinely checked to make sure you can bring your truck and trailer to a complete stop quickly. When Should You Visit Your GMC Dealer for GMC Towing Maintenance? When you frequently use your GMC truck to tow heavy hauls, it's crucial to keep up with routine maintenance. Your owner's manual recommends service intervals every 7,500 miles for tasks like checking the quality of the brake pads, rotating tires, changing motor oil, and replacing the oil filter. For average drivers, this means scheduling service every six months to maintain the top towing capability of the truck. The most essential parts of your truck that need maintenance for optimal towing performance are the wiring system, brake system, and cooling system. Your local dealership is equipped with all the wear-and-tear parts you need to streamline your truck's towing capability. Schedule service at Oxendale GMC in Flagstaff, AZ.
