Walker Products 212-1018 Engine Cooling Fan Switch

Walker Products Engine Cooling Fan Switches are OE Replacement components that regulate the operation of electric radiator or condenser fans based on engine coolant temperature. This simple yet critical component closes or opens the circuit at a precise temperature threshold—signaling the fan to activate when cooling is needed and shut off when optimal temperature is reached. A failed or misfiring fan switch can lead to overheating, extended fan operation, or poor air conditioning performance. Walker fan switches are engineered to meet or exceed OE specifications for switching temperature, electrical resistance, thread size, and connector design. Built with thermally responsive elements and sealed for protection against coolant exposure and under-hood contaminants, these units deliver dependable, long-lasting performance. Designed for exact OE fit, Walker Cooling Fan Switches thread directly into the original mounting location—typically in the radiator tank, cylinder head, or thermostat housing—and connect using the factory electrical harness. Whether performing preventive maintenance, replacing a failed unit, or correcting an overheating issue, Walker Cooling Fan Switches restore reliable fan operation, protect engine components, and maintain temperature stability under all driving conditions.
