Toyota Thermostats

Refine Results

Your vehicle's thermostat is a part that helps to regulate the flow of coolant to the engine, and it's a very important part of the cooling system in your Toyota. The engine gets really hot as you're on the road, so it's important that all parts of your cooling system are kept in good condition so it doesn't overheat. The thermostat will open as needed to allow the flow of coolant to the engine. It will close to stop the flow of coolant if your engine still needs to overheat. The thermostat is something that can wear out and might need replacement. It might become stuck in an open or closed position that can cause there to be issues with the operation of your engine. You need to be sure to pay attention to the temperature gauge to see if it fluctuates or spikes. Find OEM thermostats for your Toyota here on our site if you need a replacement.
