Coolant Temperature Sensors for BMW 7 Series E38 (1995-2001)

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!

M14x1.5 Thread. Your vehicle is equipped with numerous gauges to allow you to have a better idea of what is going on under the hood. By monitoring these gauges, you can prevent premature engine damage due to low oil pressure or high coolant temperatures. If one isn't functional though, you are in the dark as far as that system goes. One of the most vital is coolant temperature. Replace the sensor to get your gauge working properly again.
