If you’ve ever driven a car prone to overheating, constantly seems to be low on coolant, or has an unknown problem with the radiator, hoses, thermostat, or other components that help keep your engine cool, there’s rarely a happy ending. All too often, overheating happens when you’re on a road trip, a long way from a service station, or out of cell phone range. But with the right maintenance and a little diligence, keeping your car from overheating is easier than you think.
Keeping your car from overheating by keeping its radiator and cooling system in working order is important for engine performance and reliability. When your car’s cooling system is working properly, the thermostat gauge in your car should be about in the middle between hot and cold. Your car’s engine performs best when it runs at a moderate temperature. An engine that runs too hot or cold causes more wear and tear on plastic parts, decreases efficiency, and spits out more pollution in the exhaust.
Simple inspection and maintenance practices can keep your radiator and cooling system working properly and stop your car from overheating. Here are some things you can do to check on your cooling system:
Examine rubber hoses for cracks or missing rings where the hoses attach to the radiator or engine.
Make sure the rubber gasket on the radiator cap is creating a proper seal.
Monitor your thermostat while driving to make sure your engine is running at a moderate heat.
Inspect the coolant level in the reservoir.
Look for coolant leaks where you park your car.
If you take these preventive measures to monitor your car’s radiator and cooling system, you’ll be more likely to identify warning signs of a problem. Cracked hoses or a failed gasket need to be replaced. An engine running too hot or too cold, is an indicator of a radiator problem. And if coolant seems to be evaporating, you may have a leak or poorly performing radiator. Taking care of these kinds of problems you can identify on your own, can keep you from getting stranded and prevent your car from overheating.
