Keep your engine's cooling fan switching on at the right temperature with the Standard Ignition switch, model TS-428. This Engine Cooling Fan Switch drops in as a direct-fit replacement for the 1994-1995 Hyundai Elantra. It is a temperature-sensitive thermal switch that makes an electrical contact at its specified set point and passes that signal to the fan controller, telling the cooling fan when to run.
Factory-calibrated and tested: every unit is calibrated and tested to confirm switch actuation at its specified temperature, closing the electrical contact at the specified lower-temperature set point.
Wax-pellet actuation: a custom wax formulation expands when heated to activate a snap-action electrical contact and transfer the signal to the fan controller.
Bimetallic contact arm: formed from two metals with different expansion rates fused together — a creep-action device built for precise performance.
Robust build: high-grade materials and a robust design meet the demands of today's service professional.
If a failed cooling fan switch is the cause of a fan that won't come on, a fan that runs constantly, or higher-than-normal coolant temperature, this replaces it. Diagnose the circuit before replacing.
