OEM Thermostats

Refine Results

The thermostat in your vehicle is what helps to regulate the flow of coolant to your engine. It is a very important component in your car's cooling system and ensures that your engine isn't running too hot or too cold. When your engine sits for a while and isn't warmed up yet, the thermostat will remain closed to ensure it is able to get to the appropriate operating temperature. Once it reaches this temperature, a sensor opens that allows coolant to flow to and from the radiator, which decreases the temperature so that the engine doesn't overheat. It's important that the thermostat is able to open and shut at the correct time so that you can maintain the perfect engine operating temperatuere. Over time, it could become stuck open or closed, which could cause a whole host of problems for your vehicle. One thing you might notice is the tempertaure gauge climbing high within the first fifteen minutes of your engine running. This is likely the first sign something is wrong. The temperature could also change frequently and jump to high temperature and down to low ones, which can cause poor performance. Make sure to replace your thermostat with an OEM component that will fit your model and last a long time.
