Beck/Arnley Engine Cooling Fan Switch P/N:201-1520
Keep the electric cooling fan cycling on cue with the Beck/Arnley Engine Cooling Fan Switch 201-1310. 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 for many vehicles, including the 1988-1991 BMW M3 and 1986-1988 BMW 325 — see the "Vehicles it fits" section for the full list.
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.
