Product Details

This Four Seasons temperature switch is used in engine cooling systems that rely on coolant temperature to trigger fan operation. The switch opens and closes at the specified temperature points to help manage fan cycling in the radiator or engine cooling circuit.

This part cross-references Baldwin 20014 for the same application.

Common Cooling System Issues It May Address

• Cooling fan not turning on at the correct temperature
• Fan cycling too early or too late
• Temperature-related fan control faults
• Engine-mounted switch failure in the cooling circuit
• Incorrect fan operation on listed Toyota and Prizm applications

Installation Notes

Verify the connector style, thread size, and temperature range before installation. This switch uses an engine-mounted location and a male M16-1.50 fitting, so the replacement should match the original sensor port and electrical connector exactly. Confirm the vehicle application by year and model before ordering, especially on 1993-2000 Toyota and Geo/Chevrolet Prizm platforms.
