OEM Mopar Thermostats

Car thermostats help keep engines from overheating. However, a thermostat is just a simple valve; how such a small part of a car cooling system can do this, then, may not seem so obvious.

Yes, how a car thermostat works probably seems simple. A spring or piston opens and closes it, and this enables coolant to circulate properly between a radiator and an engine. However, it's auto parts moving in time, as they need to, that's key -- thermostat valve included. That's what keeps that coolant moving in a way that maintains proper temperature range, whether the weather's hot or cold.

Luckily, everything normally happens as it should. Things go so well, in fact, that car thermostat failure is rare. Thus, the question of when to replace a car thermostat hardly comes up. If you're wondering about yours, though, check your vehicle's temperature gauge. If it reads constant, with a digital display or needle that's dead-center or slightly cold, then your thermostat is working just fine. However, that doesn't mean it can't go bad, whether from use and age or some other related cause.

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

They can vary widely. Look for:

• A lit Check Engine light
• Valve operation problems
• A stuck valve
• Engine issues
• AC and heating malfunctions
• Coolant not moving correctly
• Hose and gasket warp

In such cases, you should run a complete inspection to figure out exactly what's happening. If it turns out you do need to change your car thermostat, it's best to replace it with a genuine Mopar thermostat.
