Thermostat

Refine Results

A thermostat is a device sensitive to temperature that adjusts to maintain the temperature of your Toyota in the required range. Sitting between the engine and the radiator, it helps to block the flow of coolant to the radiator until your engine has warmed up properly. It then allows coolant to flow through as needed, switching from open to closed to help keep your engine running at the perfect temperature for optimal performance. It's crucial that you pay attention to how your thermostat is functioning so that you can replace the part if needed. A sign that you might need a new thermostat is if your temperature gauge goes into the red zone shortly after warming your car up - usually within the first 15 minutes. A thermostat stuck in an open or closed position means that your engine is not going to be kept at the proper temperature. This can result in decreased performance, lowered fuel economy, and your engine can even become damaged if it overheats! Our webstore carries OEM thermostats so you can replace your old one if needed. OEM Toyota thermostats will fit your make and model perfectly and give you peace of mind that your car's temperature is just right.
