Show original supplier description
It is a crucial component that, per BMW Technical Information System (TIS) guidelines, must be replaced whenever the water pump, thermostat, or the cooling system is serviced. Crafted in the Czech Republic, this gasket carries the Genuine BMW designation, signifying that it meets the rigorous quality and performance standards expected of original equipment. Genuine BMW parts are produced under BMW's strict supervision, often by Original Equipment Manufacturers (OEMs) with decades of experience supplying the brand. This ensures you receive a part that is identical in fit, form, and function to the one originally installed on your vehicle, upholding the integrity of your Ultimate Driving Machine. This thermostat housing gasket is compatible with a wide range of BMW models, including various 323i, 323is, 325i, 325is, 328i, 328is, 525i, M3, and Z3 vehicles from the 1990s, generally from 1992 through 2000 depending on the specific engine and model. It is essential to verify fitment using your vehicle's specific year, engine, and trim details. When replacing this gasket, it is also recommended to consider replacing the thermostat O-ring (part number 11531265084) for a complete cooling system service.
