Thermostat

Refine Results

The thermostat in your vehicle plays a vital role in your cooling system. Your vehicle's engine must maintain proper temperature. The thermostat is a valve that regulates its temperature and is located between the radiator and engine. As the coolant temp rises, the thermostat begins to open, allowing hot coolant in the engine to flow into the radiator and then cooler coolant from the radiator to the engine. If your thermostat is not functioning properly, or is broken, you may notice some signs such as an overheating engine, temperature changes, and coolant leaks. Over time, thermostats can sometimes stick, which would not allow coolant to flow into your radiator to get cooled. Thermostats can also develop leaks around the seal. A leaking thermostat would need to be replaced since it cannot seal properly and hold the antifreeze inside where it belongs. If you are leaking antifreeze, that vital fluid cannot cool down your engine like it is designed to do. An overheating engine will cause many problems if you let it go and don't get the problem fixed. Here at Parts Discounters, we have genuine OEM thermostat replacements for your specific make and model vehicle. Check out all of our thermostat options below.
