Help your electric cooling fan switch on when coolant temperature calls for it with the Standard Ignition switch TS-251, an engine cooling fan switch that the manufacturer lists as a coolant fan switch. It is a direct-fit replacement for the 1985-1986 and 1988 Chevrolet Sprint, the 1985-1988 Suzuki Forsa and the 1987-1988 Pontiac Firefly. See the "Vehicles it fits" section for engine details.
This thermal switch responds to coolant temperature. When the coolant reaches the switch's calibrated set point, the switch makes electrical contact and sends a signal to the fan control circuit.
- Factory calibrated: Each thermal switch is calibrated in production to make electrical contact at its specified lower-temperature set point.
- Tested actuation: Every unit is calibrated and tested to confirm that the switch actuates at its specified temperature.
- Built for service professionals: The switch uses a robust design and high-grade materials intended to meet the demanding needs of today's service professional.
- Quality control throughout: Standard Ignition is a global manufacturer of original equipment ignition products. It maintains quality control across the whole manufacturing process, from componentry to finished product.
This part may need replacing if the cooling fan never switches on, if the fan runs constantly, or if the temperature gauge climbs at idle or in slow traffic. A fan relay, fan motor, wiring fault or low coolant can cause the same symptoms, so diagnose the cooling system first. If a failed cooling fan switch is the cause, this unit replaces it.

Frequently Asked Questions
What does the Standard Ignition TS-251 do?
It is a thermal switch. When coolant reaches the calibrated set point, it makes electrical contact and signals the fan control circuit to switch on the electric cooling fan.
Which vehicles does the TS-251 fit?
It is listed for the 1985-1986 and 1988 Chevrolet Sprint, the 1985-1988 Suzuki Forsa and the 1987-1988 Pontiac Firefly. See the "Vehicles it fits" section for engine details.
What are signs a coolant fan switch may need replacing?
Common signs are a fan that won't come on, a fan that never shuts off, or a temperature gauge rising at idle. A bad relay, fan motor, wiring or low coolant can do the same, so diagnose first.
Is each switch tested before it ships?
Yes. Every unit is calibrated and tested to confirm that the switch actuates at its specified temperature set point.
What part numbers does the TS-251 cross-reference?
It crosses to TFS11, SW587, FS116, 96051827, 96067621, 1768082011 and 1768086011.
