What do car radiators do for engines? Simply put, they keep them running as cool as possible. In fact, they help prevent overheating. How a car radiator works, though, is more complex. Inside your GM vehicle, for instance, it all starts with coolant. The liquid travels through a radiator hose and back and forth between inlets and outlets, compressed by a radiator cap as it moves. While it circulates, it captures engine heat. A set of fins then expels the heat, and a fan blows it away. The result: your engine not only works properly. It also lasts longer. Any factory radiator can go bad, though. When it does, it causes problems like HVAC malfunctions, not to mention engine overheats and shutdowns.
What are the Signs of Radiator Problems?
Listen for weird engine noises, look for sludgy coolant and fin damage, and smell for a sweet, syrupy aroma. The last is ethylene glycol, and it usually indicates a coolant leak. If you think your radiator is near failure, check your temperature gauge. Its needle will tell you if your engine's running too hot. Then, run a full inspection. If the results call for replacement, avoid the aftermarket. A genuine GM radiator will fit your make and model best. Our auto parts store has plenty, and you can order one online direct from your OEM in just a few clicks. So, cross another job off your list of to-dos. Buy now!
