OEM GM Radiators

Refine Results
To work right, an engine needs to avoid overheating. What does the best job of helping one run relatively cool? Your factory GM radiator. How car radiators work starts with coolant. This fluid is designed to absorb the heat produced during engine operation. It does so as it flows through a radiator hose and between inlets and outlets. As it moves back and forth, a radiator cap compresses it, enabling it to absorb as much heat as it can. The aluminum fins on your radiator core block then release the heat, and a fan dissipates it. The result: your engine works better and lasts longer. When a radiator goes bad, however, you'll start to see all sorts of signs. Luckily, they're easy to recognize. The most obvious symptom of radiator failure is fin damage. Others range from strange engine noise and the sweet, syrupy smell of ethylene glycol (indicating coolant leakage) to sludgy coolant. You may even see your heater and air conditioner start to malfunction. The worst sign of a bad radiator, though, is an engine overheat. Engine failure often follows. If you have what you think are radiator problems, check your temperature gauge first. It'll let you know if your engine's running hot. Then, do an inspection. If radiator replacement is necessary, avoid the aftermarket. Our auto parts store has the best solution. That's a genuine GM radiator. Your OEM designs them specifically for its models, after all, and that guarantees they'll work together. Check another big DIY project off your to-dos -- order online now!
