Product Description

The 1998-2003 BMW 540i Thermostat Assembly is designed for installation in vehicles with an E39 M62 engine. It is built out of stainless steel and helps control the flow of coolant to the engine, managing normal operating temperatures during the start up and typical driving conditions of the vehicle. The product features a housing and gasket and is sold as a single unit for all sub-models and engine types in the 1998-2003 BMW 540i series. Engine wear and deposits, along with atmospheric emissions, are reduced when the product is installed, and it also restores these benefits when the original thermostat begins to break down or has failed.
