Keep the engine cooling fan cycling on cue with the Standard Ignition Engine Cooling Fan Switch TS-108. This coolant fan switch drops in as a direct-fit replacement for many vehicles, among them the 1975-1978 Fiat 131, 1974-1978 Fiat X-1/9 and 1968-1977 Fiat 124; see the Buyer's Guide tab for the full list.

This thermal switch senses coolant temperature and, at its calibrated set point, closes an electrical contact to transfer the signal to the fan controller so the cooling fan runs when it should.

  • Wax-pellet actuation: a custom wax formulation expands when heated to trigger a snap-action electrical contact that signals the fan controller.
  • Bimetallic contact arm: a formed bimetallic arm uses the different expansion rates of two fused metals for precise creep-action performance.
  • Factory-calibrated: every unit is calibrated and tested to confirm switch actuation at its specified lower-temperature set point.
  • Built for service demands: robust design and high-grade materials meet the stringent demands of today's service professional.

Signs this switch may need replacing include a cooling fan that fails to turn on, a fan that runs constantly, or engine overheating. If a failed fan switch is the cause, this replaces it; diagnose the circuit to confirm before installing.

Frequently Asked Questions

What does the TS-108 cooling fan switch do?

It is a thermal switch that senses coolant temperature and closes an electrical contact at its calibrated set point, transferring the signal to the fan controller so the cooling fan runs when needed.

Which vehicles does this switch fit?

It fits many vehicles, among them the 1975-1978 Fiat 131, 1974-1978 Fiat X-1/9 and 1968-1977 Fiat 124. See the Buyer's Guide tab for the full list.

How does the switch activate the fan?

A custom wax pellet expands when heated to trigger a snap-action electrical contact. A formed bimetallic contact arm uses the different expansion rates of two fused metals for precise creep-action performance.

What are signs this fan switch may be failing?

A cooling fan that never turns on, a fan that runs constantly, or engine overheating can be signs. Diagnose the circuit first, since these symptoms can have other causes.

Is the switch calibrated before it ships?

Yes. Every unit is factory-calibrated and tested to confirm switch actuation at its specified lower-temperature set point.
