Keep your engine's cooling fan switching on at the right temperature with the Standard Ignition switch TS-363, a coolant fan switch that drops in as a direct-fit replacement for the 1984-1989 Toyota Van and the 1988 Toyota Van Wagon. This thermal switch senses coolant temperature and closes its electrical contact at the calibrated set point, transferring the signal to the fan controller so the cooling fan is commanded on.
Wax-pellet actuation: a custom wax formulation expands when heated to trip a snap-action electrical contact and pass the signal to the fan controller.
Calibrated and tested: wax pellets are custom formed for the specified temperature range, and every unit is factory-calibrated and tested to confirm actuation at its specified lower-temperature set point.
Built for service: robust design and high-grade materials made to meet the demands of the service professional.
If a failed coolant fan switch is the cause of a fan that won't come on or an engine that runs hot, this replaces it; diagnose the cooling system first, since these signs can have other causes. This is a common Van switch replacement.
