Standard Motor Products TS119 Engine Coolant Fan Switch - 2-Terminal M16-1.50

The Standard Motor Products TS119 is a direct-replacement engine coolant fan switch (also known as a radiator fan switch or cooling fan temperature switch) engineered to restore proper electric cooling fan operation. This thermostatic switch monitors coolant temperature and signals the fan controller to engage or disengage the cooling fan at the correct set point, helping prevent engine overheating.

Standard Motor Products engineers this switch using a custom wax pellet formulation that expands when heated, activating a snap-action electrical contact that transfers the signal to the fan controller. Every unit is factory-calibrated and tested to confirm switch actuation at its specified temperature set point, ensuring consistent, repeatable performance.
