Engine Coolant Level Sensor

Description

Walker Products Engine Coolant Level Sensors are OE Replacement components designed to monitor the level of coolant in the reservoir or radiator and alert the ECU or driver when fluid drops below safe operating levels. This critical sensor prevents overheating by activating dashboard warning lights or triggering ECU-based engine protection strategies. Each Walker sensor is engineered to meet or exceed OE specifications for float mechanism response, electrical signal behavior, and fluid resistance. Built from durable, heat-resistant materials, these sensors are designed to withstand constant immersion in coolant as well as the high-temperature, high-vibration conditions found in modern engine bays. Designed for an exact OE fit, they connect seamlessly to the factory wiring harness and mount directly in the original sensor port—eliminating the need for any modifications. Whether used for routine replacement or to resolve an intermittent warning light or coolant-related fault code, Walker Coolant Level Sensors help ensure safe engine operation, avoid overheating, and maintain optimal system performance.
