Keep the electric cooling fan cycling on cue with the Beck/Arnley Engine Cooling Fan Switch 201-1310 — the M3 switch many BMW and Volvo owners search for. This thermo fan switch senses engine coolant temperature and opens or closes the circuit that turns the electric cooling fan on and off, helping the engine hold its normal operating range. It drops in as a direct-fit replacement across a wide list of applications, including the 1988-1991 BMW M3, 1986-1988 BMW 325, 1977-1983 BMW 320I, 1979-1981 BMW 528I, and the 1985-1988 Volvo 740 — see the Buyer’s Guide tab for the full list.
- OE match: Built to match OE form, fit and function for foreign-nameplate applications.
- Application specific: Made for your vehicle — check the catalog data and confirm fit before ordering.
- Diagnose first: Professional diagnostics are recommended for a successful repair.
- Check the circuit: Verify cooling fan motor current draw, control module/relay function, and the electrical wiring and connectors.
If a failed switch is why your fan won’t come on or runs constantly, this replaces the original unit. Diagnose the cause before replacing, since fan behavior can also trace to the motor, relay, module, or wiring.
