Do You Need a Radiator Repair at Your Chevy Dealer?

A close up of car repair tools

A good radiator is essential for keeping your Chevy running efficiently. The radiator removes engine heat to protect your engine against overheating. Over time, parts can wear out or get damaged, and you'll need a radiator repair at your Chevy dealer. These are some possible signs your radiator may soon need a repair.

Rust on the Radiator

If you see signs of rust on your radiator, this is a cause for concern. Under normal circumstances, your car's radiator is never exposed to water, and water is necessary to create rust on metal. The most likely cause of the rust is that your cooling system has a leak and is spilling coolant as you drive. Even a tiny hole in the system can allow the pressurized coolant to escape.

Coolant is a mix of antifreeze and water, and if coolant spills onto the radiator it can quickly enable rust to develop. Coolant evaporates quickly in the engine heat but leaves behind tell-tale white marks. If you see these marks, you have a coolant leak. Our technicians will examine your radiator and the cooling system to find and fix the source of the leak.

Damaged Radiator Fins

The fins are rows of thin aluminum tubes in the front of your radiator. These tubes provide the cooling surface for removing heat from your engine. The hot coolant is pumped into the radiator and enters the rows of tubes. The air flowing through the grille as your car moves cools these tubes and the liquid inside them. Once the coolant has cooled, it's pumped out of the radiator and recirculated through your engine.

These fins can get damaged by grit, sand, and other debris thrown up from the road surface. This debris is drawn through the grille and can dent and damage the tubes. As more tubes become damaged, your car's cooling system will suffer. Coolant will flow slower through the system due to the blocked tubes, which increases your engine temperature. We can't repair the damaged tubes, but we can replace the radiator.

Broken Thermostat

The thermostat in your cooling system is set to a particular temperature, which is usually around 185F. When your engine reaches this temperature, the thermostat opens and releases coolant into the engine. The coolant is then pumped through the system to absorb the heat. A thermostat is a simple component, but it can wear out.

A worn thermostat could jam closed, which prevents coolant from being released. Without the constant flow of coolant, your engine can overheat. Our technicians can easily replace the thermostat with a new one.

Maintaining Your Chevy's Exhaust System

The exhaust system tucked away under your car requires diligent maintenance just like any other vital component. With the following Chevy exhaust maintenance guidelines, you'll help your engine and entire car run more smoothly and efficiently. Clean Your Exhaust Frequently Regular cleans will combat corrosion and reduce the buildup of carbon deposits, which might otherwise restrict the outflow of fumes. Use an old rag, soap, water, degreaser, and polish to clean the outside of the pipes and as far into the tailpipes as possible. Frequent cleans are especially important during our icy Pennsylvanian winters, when snow and salty slush from the road can have a highly corrosive effect. more Protect Your Exhaust From Rust Rust is one of the chief dangers any exhaust can face. Rapidly rising temperatures create condensation inside the exhaust pipes, which encourages rust. Consider applying temperature-resistant paint and rust inhibitors to protect the metal from external corrosion. Also, regularly check your exhaust pipes for rust. If you catch minor rust early and remove it using an effective degreaser with steel wool, you'll save your exhaust pipes from cracks and leaks down the road. Avoid Short Drives of Under Five Miles Internal rust is harder to spot. Your best defense against this threat is regular drives, which generate the heat required to remove internal puddles of moisture. However, it's important to take longer drives, ideally out on the highway. If you only make short trips of under five miles, the heating exhaust will create condensation, which then settles inside the exhaust when you stop driving. If you keep driving for another ten or twenty minutes instead, all the moisture will get thrust out of the tailpipe or evaporated away. Discard Aggressive Driving Habits The rapid accelerating and braking that characterizes aggressive driving has a detrimental impact on exhaust systems. If you adopt calmer driving habits, your exhaust, engine, transmission, and brakes will all suffer less strain and reward you with better long-term performance. Idling is also harsh on the exhaust and should be avoided where possible. Overloading your car by carrying or towing too much weight could also cause premature wear and tear. Book Regular Chevy Exhaust Maintenance Without a trained eye or the ability to safely raise your car, it's difficult to properly inspect an exhaust system. At least once a year, have a trusted technician thoroughly inspect and test the manifolds, catalytic converter, resonator, muffler, oxygen sensors, brackets, and every other exhaust component for cracks, corrosion, looseness, and abnormalities. Any issues can be quickly repaired to keep your exhaust and engine running efficiently. Schedule an exhaust inspection today at Mike Kelly Chevrolet in Butler, PA. Our technicians are Chevrolet experts dedicated to quality work and great customer service.

Maintaining Your Chevy's Suspension System

Do you ever wonder why your Chevy drives so smoothly? Excellent suspension is the answer; but without regular maintenance, even the best suspension will suffer wear and tear, eventually causing the car to bounce, sway, dip, and become less precise in its overall handling. You can keep your drives easy and smooth with the following Chevy suspension maintenance protocol. Maintaining Your Chevy's Suspension System Keep Your Tires Properly Inflated When tires aren't at exactly the correct PSI in terms of air pressure, excess strain is placed on the suspension. This pushes the shocks and struts out of shape and also puts you at risk of skids and blowouts. more Routinely Rotate Your Tires Car tires tend to wear down unevenly, a phenomenon easily corrected with regular tire rotations. It's advisable to keep your tires uniform in size and wear patterns with rotations twice a year. This helps your tires last longer and protects your suspension from harm. Avoid Rougher Roads Suspension systems are most strained by rougher roads and potholes. The more you can avoid bad roads, the longer your suspension will last. If you do need to use poorly maintained roads a lot, or you're a fan of off-roading, have your suspension and wheel alignment checked and corrected more often. Realigned Your Wheels Over time, car wheels become pushed slightly out of position by continual bumps against potholes and curbs. It's advisable to have your wheel alignment measured at least twice a year. If any of your wheels are found to be out of proper alignment, have them realigned, a process that involves precision machinery and adjustments to the shocks, struts, and springs. Clean Your Suspension When you clean your car, don't forget to clean thoroughly beneath the undercarriage too. If snow, mud, sand, or general grime builds up on the shocks, struts, control arms, and springs, it accelerates corrosion. Repair Suspension Faults Promptly If you notice signs of worn-out suspension parts, don't hesitate to have the faulty component replaced. A malfunctioning suspension may cause your car to bounce excessively after bumps and dips in the road. You may find the nose dipping forward when you brake or the entire vehicle leaning to the side when you corner. A weakening suspension at just one wheel may also cause the car to lean towards that corner when it's parked. Book Chevy Suspension Maintenance As with any important car part, it's wise to routinely have your suspension inspected by a professional. Once a year is a good interval for most cars. During an inspection, our experienced technicians can check every suspension part and keep you informed of how much longer they're likely to last. Visit Mike Kelly Chevrolet in Butler, PA, today to have your suspension inspected or repaired. For over 60 years, we've been helping drivers enjoy safer, smoother, more enjoyable rides.

Chevy Cabin Air Filter Replacement: Importance and Schedule

If your car becomes dusty faster than usual, or if the cabin smells unpleasant with no obvious cause, then it might be time to replace your Chevy cabin air filter.  Changing the filter regularly is vital, as it plays an important role in keeping contaminants out of the car. more What Does Your Chevy Cabin Air Filter Do? Keeps Your Interior Clean Catching dust and dirt is part of your cabin air filter's job. This helps keep those contaminants out of your car, keeping it cleaner. With no dust or dirt buildup, you don't need to wipe down the surfaces to get rid of dust as often, and it helps the interior last longer by keeping it free of things that could damage it. Keeps Contaminants Out Some things that your air filter keeps out can be hazardous. Twigs, rodent droppings, soot, leaves, and insects are just some of the more harmful things that your filter may keep at bay. Different filters are designed to keep different contaminants out of the car, but they all work to keep the interior as contaminant-free as possible. Keeps You Safe and Healthy By keeping contaminants out of the cabin, the air filter doesn't just keep you safe from breathing in harmful and unhealthy substances. It can also keep pollen and other allergens out of the car. Keeping allergens out can improve your safety by reducing symptoms such as blurry vision and sneezing. Dealing with these symptoms while driving can be distracting and make driving more dangerous. How Often Should You Change Your Cabin Air Filter? How often your air filter needs to be changed varies depending on several factors, including how much you drive and the environments you drive in most often. Learning the signs that you need to change the air filter, or asking the technicians at your local dealership for advice, can help you get a good idea of how often you will need to change yours. Your owner's manual may also recommend how often you need to change the air filter. For example, a recommendation from the owner's manual of a 2025 Chevy model says to change the air filter every 36,000 miles or every 24 months. What Happens If You Don't Change Your Cabin Air Filter? Not getting your cabin air filter changed can lead to more dust buildup in your car, weak airflow from the vents, and a bad smell that doesn't go away, no matter how much you clean your cabin. The smell could be mildew or other bacteria in your vents, and your old, clogged filters can't filter it out properly. Visit Mike Kelly Chevrolet in Butler, PA, to get your air filter changed regularly. Coming by for service twice a year is ideal for keeping your car in excellent condition. Image via Chevrolet
