Keep the cooling fan cycling on temperature with the Standard Ignition switch (TS-148), a coolant fan switch that installs as a direct-fit replacement for the listed applications. It fits many vehicles, among them the 1986-1988 Nissan Sentra, 1985-1986 Nissan Maxima and 1987-1989 Nissan Pulsar NX. This thermal switch senses coolant temperature and closes an electrical contact at its calibrated set point to signal the fan controller.

  • Snap-action contact: a custom wax formulation expands when heated to trip a snap-action electrical contact and transfer the signal to the fan controller.
  • Factory-calibrated: every unit is calibrated and tested to confirm actuation at its specified lower-temperature set point.
  • Bimetallic contact arm: a formed arm fuses two metals with different expansion rates for a creep-action device tuned for precise performance.
  • Built for service: robust design and high-grade materials meet the demands of today's service professional.

If a failed coolant fan switch is the cause of a fan that won't cycle correctly, this switch replaces the worn original. See the Buyer's Guide tab for the full vehicle list and engine-level fitment details on your vehicle.
