Genuine GM Thermostats

Refine Results

What do car thermostats do? Put simply, they help prevent engine overheats. However, they're just simple valves, and how such a small part of a cooling system can achieve this isn't so obvious. Yes, how one works may be simple -- a spring or piston opens and closes it, enabling coolant to circulate between an engine and a radiator. However, it's synchrony that's key. It's what keeps coolant moving in a way that keeps it in the right temperature range, hot weather or cold. Many other auto parts pitch in on the process, and everything happens as it should -- so well, in fact, that car thermostat failure is very rare. So, the question of when to replace a car thermostat? It doesn't come up often. If you're wondering, check your temperature gauge. If it reads constant, with a needle that's dead-center or in the slightly cold range, then your thermostat's working just fine. However, that doesn't mean it can't go bad, whether from age or some other cause.

What are the Symptoms of a Car Thermostat Not Working Right?

They vary. Look for a lit Check Engine light, valve operation problems, a stuck valve, engine issues, AC and heating malfunctions, coolant not moving correctly, and hose and gasket warp. In these cases, run a complete inspection to figure out what's going on. If you need to change your car thermostat, it's best to replace it with a genuine GM thermostat. You can buy one online directly from your OEM via our auto parts counter. So, enjoy peace of mind down the road -- order now.
