The Symptoms of a Clogged Radiator range from something as little as the temperature gauge rising to steam billowing from under the hood of your vehicle. Other than your car running hot, some other signs of a clogged radiator include radiator hose cracks, low coolant, coolant that looks rusty, and coolant leaks. If you get a coolant warning light or need to add coolant to the radiator, then you probably have a radiator that’s ready to fail, and it ought to be examined ASAP. Your vehicle needs its radiator to function properly to avoid getting too hot, which could eventually lead to catastrophic engine failure.



What Does The Radiator Do?

What Does Coolant Do?

The primary job of a radiator is to prevent damage to your car’s engine caused by overheating. You may not realize it, but the radiator and coolant are absolutely necessary to keep your vehicle in top condition. The coolant absorbs heat as it moves through the engine, then returns back to the radiator, is cooled back down, and then the cycle is repeated. Besides preventing the engine from overheating, it also lubricates other engine components as it circulates through the system. Your vehicle would overheat in moments without a radiator and coolant.

Coolant can last anywhere from 30,000 to 120,000 miles. But, just like the oil or transmission fluid in your car, it is imperative to check the levels and service them at the correct intervals. With such a wide range, depending on your driving habits, it could last many years, so it is important to review the suggested maintenance intervals. If you have any questions about the longevity of your coolant, bring your vehicle to one of our certified techs, who can ensure everything is in good shape.

If you suspect there might be an issue with your radiator or coolant, bring it in for a thorough inspection. A bad radiator can cause damage to not only the engine but other components, resulting in even more expensive repairs. Bringing your car in for routine maintenance is the best way to keep unexpected repair costs from getting out of hand.
