A common cause of cooling system performance issues

This thermostat assembly is a common wear item and usually a culprit for all sorts of issues with the cooling system. Thermostats typically fail in one of two ways. The most common failure occurs when the thermostat gets stuck in the open position. This allows coolant to continually pass through the engine preventing it from reaching operating temperature. Engines that don't run cool like this will usually receive poor gas mileage. Another failure is when the thermostat gets stuck in the closed position. This will cause your engine to constantly overheat which can damage the engine. This thermostat comes with the gasket for an easy installation.

Simple, Clean And Quick

The product came earlier than predicted, which is alway a good thing! It was the exact part I asked for and matched perfectly to the original BMW part on the car. PLEASE NOTE: The housing ALREADY COMES WITH THE HOUSING GASKET, so there is no need to purchase a housing gasket if you are buying this housing!

Some of the reviewers above may have been rewarded for their positive & negative reviews. We don't hold anything back.
