OEM Dodge Thermostats

What does a car thermostat do? Put simply, it helps prevent engine overheats. However, it's just a simple valve, and how such a small part of a cooling system -- one of the many -- can achieve this is less obvious. Yes, how a car thermostat works is simple: a spring or piston opens and closes it, and this helps coolant circulate between your engine and radiator. However, it's getting the right intervals that's key. (After all, coolant has to stay in the right temperature range, whether the weather's hot out or cold.) Luckily, many other auto parts pitch in, and everything happens the way it should. It all works so well together, in fact, that car thermostat failure is rare. So, the question of when to replace a car thermostat doesn't come up often. If your temperature gauge reads constant, with a needle that's dead-center or slightly in the cold range, then, great news: your thermostat's working just fine. However, that doesn't mean it can't go bad, whether from age or otherwise.

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

They vary widely. Signs include a lit Check Engine light, valve operation problems, stuck valves, engine problems, and AC and heating malfunctions. In short, if you have a non-working thermostat valve, it won't move coolant correctly. This can either result in an overheat or coolant being unable to reach the appropriate temperature. Engine efficiency drops, and even the surrounding hoses and gaskets can warp, that is, if they don't otherwise fail. In these cases, run a complete inspection. If you need to change your car thermostat, it's best to replace it with a genuine Mopar thermostat. You can order one online from your OEM via our auto parts counter.
