Keep your engine's cooling fan responding to coolant temperature with the Beck/Arnley Engine Cooling Fan Switch 201-1778 (also written 2011778). This thermo fan switch senses engine temperature and opens or closes the circuit that triggers the cooling fan, so the fan runs when the coolant reaches its set point. It's a direct-fit replacement for the 1997-1998 BMW 528I and 540I; the 1995 and 1997-1998 BMW 740I and 740IL; and the 1995-1998 BMW 750IL. See the Buyer's Guide tab for engine details and to confirm the correct application for your vehicle.
