Description

Keep the cooling fan cycling on cue with the Standard Ignition Engine Cooling Fan Switch (TS-177, also written TS177). This thermal switch senses coolant temperature and closes an electrical contact to signal the fan controller, and it drops in as a direct-fit replacement for the 1986-1989 Honda Accord and the 1985-1991 Honda Prelude. See the "Vehicles it fits" section for engine-level fitment.

As a global manufacturer of original-equipment ignition products, Standard Ignition maintains quality control from componentry through the finished switch. Key features:

Snap-action switching: a custom wax formulation expands when heated to trip a snap-action electrical contact and pass the signal to the fan controller.
Calibrated set point: wax pellets are custom formed for the specified temperature range, and each unit is factory-calibrated and tested to confirm actuation at its set point.
Bimetallic contact arm: a formed bimetallic arm uses the differing expansion rates of two fused metals as a creep-action device for precise performance.
Durable build: robust design and high-grade materials meet the demands of the service professional.

If a faulty original fan switch is the cause of a fan that won't engage or an engine that runs hot, this Standard Ignition switch replaces it — a quality 1986-1989 Honda Accord switch for the listed applications.

Buyer's Q&A

Frequently Asked Questions

What does the TS-177 coolant fan switch do?

It senses coolant temperature and, at its calibrated set point, closes an electrical contact to signal the fan controller so the engine cooling fan turns on. It's a thermal snap-action switch.

Which vehicles does this Standard Ignition switch fit?

It's a direct-fit replacement for the 1986-1989 Honda Accord and the 1985-1991 Honda Prelude. Check the "Vehicles it fits" section to confirm the application for your exact vehicle.

What are signs this fan switch may need replacing?

A cooling fan that won't engage, an engine that runs hotter than normal, or a fan that runs constantly can point to a failed switch. Diagnose the cause before replacing, as other components can produce these symptoms.

How is the switch calibrated?

Wax pellets are custom formed for the specified temperature range, and each unit is factory-calibrated and tested to confirm it actuates at its lower-temperature set point.
