Description

Keep the radiator fan cycling on cue with the Standard Ignition Engine Cooling Fan Switch TS-230, a direct-fit replacement for the 1974-1978 Toyota Corolla. This coolant fan switch senses engine coolant temperature and makes an electrical contact at its calibrated set point to signal the fan controller — when the original switch on your 1974-1978 Toyota Corolla has failed, this Standard Ignition switch replaces it. If an overheating condition traces back to a fan that no longer turns on at temperature, replacing a failed switch addresses that part of the circuit.

Wax-pellet actuation: a custom wax formulation expands when heated to drive a snap-action electrical contact and transfer the signal to the fan controller.
Calibrated & tested: wax pellets are custom-formed for the specified temperature range, and every unit is factory-calibrated and tested to confirm switch actuation at its specified lower-temperature set point.
Bimetallic contact arm: a formed bimetal arm uses the differing expansion rates of two fused metals for precise creep-action performance.
Robust build: high-grade materials designed to meet the demands of today's service professional.

Buyer's Q&A

Frequently Asked Questions

What does the TS-230 cooling fan switch do?

It senses engine coolant temperature and closes an electrical contact at its calibrated set point, sending the signal that tells the fan controller to switch the cooling fan on.

Does this Standard Ignition switch fit my 1974-1978 Toyota Corolla?

It is a direct-fit replacement for the 1974-1978 Toyota Corolla. Check the "Vehicles it fits" section and match your existing switch to confirm fitment for your vehicle.

How does the switch actuate?

A custom wax pellet expands when heated to drive a snap-action contact, while a formed bimetallic contact arm provides precise creep-action movement at the specified temperature.

What are signs this fan switch may need replacing?

A cooling fan that never comes on at temperature, or one that cycles incorrectly, can point to a failed switch. Diagnose the cause first, since other components can produce the same symptom.

What numbers does the TS-230 cross-reference?

It interchanges with WT538, TS5523, 25174217 and 8942812030. Standard Ignition markets this part as TS-230, also written TS230.
