Keep your electric cooling fan responding to engine coolant temperature with the Standard Ignition switch TS-236, an engine cooling fan switch that the manufacturer lists as a coolant fan switch. It is a direct-fit replacement for the 1986 Ford Mustang and the 1985-1986 Ford Thunderbird. See the "Vehicles it fits" section for engine details.
The switch senses engine coolant temperature. When the coolant reaches the switch's specified set point, it makes electrical contact and sends the signal the fan circuit uses to turn the cooling fan on. If you need a Thunderbird switch for the 1985-1986 Ford Thunderbird, or a switch for the 1986 Ford Mustang, this unit covers both listed applications.
- Calibrated set point: Each switch is factory-calibrated 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.
- Controlled production: Standard Ignition is a global manufacturer of original equipment ignition products. It maintains complete quality control throughout manufacturing, from componentry to the finished product.
- Built for the shop: The switch has a robust design and uses high-grade materials to meet the demands of today's service professionals.
Signs this part may need replacing:
- An electric cooling fan that doesn't come on as the engine warms up
- A fan that runs all the time
- A temperature gauge that climbs at idle or in traffic
Wiring, a relay or the fan motor can cause the same symptoms, so diagnose the fan circuit before replacing the switch.

Frequently Asked Questions
What does the Standard Ignition TS-236 do?
It senses engine coolant temperature. At its specified set point it makes electrical contact and signals the cooling fan circuit, so the electric fan can switch on.
Is this the right Mustang switch for a 1986 Ford Mustang?
TS-236 is listed for the 1986 Ford Mustang. See the "Vehicles it fits" section for engine details before ordering.
What part numbers does TS-236 interchange with?
It interchanges with TFS27, FS125 and E5SZ8B607A.
Is the switch tested before it ships?
Yes. Standard Ignition calibrates and tests every unit to confirm the switch actuates at its specified temperature.
What are signs a cooling fan switch may be failing?
Common signs are a fan that won't come on as the engine warms, a fan that runs constantly, or rising temperature at idle. Check the wiring, relay and fan motor too before replacing the switch.
