Keep your BMW's cooling fan cycling on at the right temperature with the Standard Ignition Engine Cooling Fan Switch TS-288 (also written TS288). This coolant fan switch drops in as a direct-fit replacement across a wide range of BMWs, including the 1984-1985 BMW 318i, 1987-1994 BMW 325i and 1987-1994 BMW 325is — see the Buyer's Guide tab for the full list of applications.

Built by a global manufacturer of original-equipment ignition products with quality control maintained from componentry to finished switch.

  • Snap-action switching: a custom wax formulation expands when heated to trigger a snap-action electrical contact and transfer the signal to the fan controller.
  • Factory-calibrated: wax pellets are custom-formed for the temperature-range specification, and every unit is calibrated and tested to confirm actuation at its specified lower-temperature set point.
  • Bimetallic contact arm: a formed bimetallic arm uses the different expansion rates of two fused metals as a creep-action device for precise performance.
  • Service-grade build: robust design and high-grade materials meet the demands of today's service professional.

If a failed fan switch is the cause of an overheating or non-cycling fan, the TS-288 replaces it with a new temperature-triggered contact.
