Toyota Thermostats

Refine Results

There are a number of parts that make up the cooling system in your Toyota. All of these parts are crucial to maintain, because your engine is something that needs to be at the right temperature to operate properly. The thermostat is one of these important components that is a part of your system. The thermostat is responsible for regulating the flow of coolant through to your engine. When your engine is running and has warmed up to a certain temperature, your thermostat has a sensor that causes it to open and allow coolant through to the engine. The constant flow and opening and closing of the thermostat is what keeps the engine temperature just right. If the thermostat starts to wear down, it can become stuck in an open or closed position. This can cause the temperature of your engine to be impacted negatively. You might find that the temperature gauge in your vehicle is reading excessively high within the first fifteen minutes of starting the car. You also can see dramatic drops or spikes in temperature that will lead to poor performance. Find an OEM replacement thermostat here for your Toyota vehicle.
