Please ensure your correct model is selected

Coolant temperature sensors are vital to your cooling system. If you're running a stock cooling system, a non-functional coolant temperature sensor can prevent your fan from flipping on or give you an inaccurate temp reading, preventing you from knowing when your vehicle is running hot. This can be a huge issue in particular if you're tracking your vehicle. Replace yours today!
