Product Description

Wahler makes this 2001 to 2005 BMW 325i car thermostat assembly. The thermostat is used to control the flow of coolant into the radiator. When the engine first starts up, its operating temperature is low. Cooling the engine is not needed at this time, and the thermostat assembly prevents the coolant from entering the radiator. When the thermostat detects that the engine has reached a preset temperature, it opens a valve so the coolant can have heat it picked up from the engine removed in the radiator. This Wahler thermostat assembly comes with the gasket and housing. It should be installed on BMW 325i cars made in 2001, 2002, 2003, 2004, and 2005. It may not be compatible with the cooling system of other vehicles.


  • Strict quality control, and functional testing
  • Self-cleaning and self-aligning thermostat valve
  • Original equipment design provides exact fit and performance
  • Precise sealing edges reduce leakage and premature cooling
  • Temperature sensitive heat motor provides consistent valve response for smooth performance and precise engine cooling
  • Stainless steel assembly and springs are engineered for long life
