Keep the cooling fan switching on at the right coolant temperature with the Standard Ignition Engine Cooling Fan Switch TS-292. This thermal switch senses coolant temperature and transfers the electrical signal to the fan controller, and it drops in as a direct-fit replacement for the 1989 and 1991 Chevrolet Sprint, 1989-1991 Pontiac Firefly, 1993-1994 Subaru Justy, and 1989-1994 Suzuki Swift. See the Buyer's Guide tab for engine-specific coverage.
- Snap-action wax design: Uses a custom wax formulation that expands when heated to activate a snap-action electrical contact and transfer the signal to the fan controller.
- Factory-calibrated: Each thermal switch is factory-calibrated and tested to make electrical contact at its specified lower-temperature set point.
- Bimetallic contact arm: Built with a formed bimetallic contact arm; the movement relies on the different expansion rates of two metals fused together 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.
Signs this switch may need replacing include a cooling fan that fails to engage as the engine warms, or one that runs constantly. If a failed switch is the cause, this replaces it — diagnose the circuit first.

Frequently Asked Questions
What does the TS-292 cooling fan switch do?
It senses coolant temperature and, at its calibrated set point, closes an electrical contact that transfers the signal to the fan controller to switch the cooling fan on.
Which vehicles does this switch fit?
It fits the 1989 and 1991 Chevrolet Sprint, 1989-1991 Pontiac Firefly, 1993-1994 Subaru Justy, and 1989-1994 Suzuki Swift. Check the Buyer's Guide tab to confirm your vehicle.
How does the switch actuate?
A custom wax formulation expands when heated to trigger a snap-action contact, working alongside a formed bimetallic contact arm that moves via the differing expansion rates of two fused metals.
What are signs this switch may be failing?
A cooling fan that won't engage as the engine warms up, or a fan that runs constantly, may point to the switch. Diagnose the circuit before replacing, since other causes are possible.
Is the switch tested before shipping?
Yes. All units are factory-calibrated and tested to confirm switch actuation at the specified lower-temperature set point.
