Keep the cooling fan cycling at the right coolant temperature with the Standard Ignition Engine Cooling Fan Switch TS-292 (also written TS292). It fits many vehicles, among them the 1991 Chevrolet Sprint, 1993-1994 Subaru Justy and 1989-1991 Pontiac Firefly, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine-level details. This coolant fan switch reads engine coolant temperature and closes its electrical contact at the specified set point to signal the fan controller.
- Wax-actuated snap contact: a custom wax formulation expands when heated, triggering a snap-action electrical contact that transfers the signal to the fan controller.
- Calibrated and tested: wax pellets are custom-formed for the temperature range, and every unit is calibrated and tested to confirm actuation at its specified temperature.
- Factory-set lower-temperature point: the thermal switch is factory-calibrated to make electrical contact at the specified lower-temperature set point.
- Bimetallic contact arm: a formed bimetal arm fuses two metals with different expansion rates in a creep-action design for precise performance.
Built with high-grade materials to meet the demands of today's service professional. If a failed coolant fan switch is the cause of a fan that won't turn on or an engine that overheats, this replaces it — diagnose the cause before replacing.

Frequently Asked Questions
What does this coolant temperature switch do?
It senses engine coolant temperature and closes an electrical contact at the specified set point, signaling the fan controller to switch the cooling fan on.
Is this Sprint switch right for my 1991 Chevrolet Sprint?
Yes, it is listed for the 1991 Chevrolet Sprint. Check the "Vehicles it fits" section for engine-level details for your specific vehicle.
What other vehicles does the TS-292 fit?
It fits many vehicles, including the 1993-1994 Subaru Justy and 1989-1991 Pontiac Firefly. See the "Vehicles it fits" section for the full list.
What are signs this switch may need replacing?
A cooling fan that won't turn on, runs constantly, or an engine that overheats can be signs — other causes are possible, so diagnose before replacing.
How does the switch activate the fan?
A custom wax pellet expands as coolant heats, driving a snap-action contact; a bimetallic creep-action arm uses two fused metals' expansion rates for precise actuation.
