Walker Products 211-1065 Engine Coolant Temperature Sensor

Walker Products Engine Coolant Temperature Sensors are designed to provide the engine control module (ECM) with real-time temperature data from the cooling system. This information is essential for proper fuel injection, ignition timing, cold start enrichment, and fan operation. An accurate reading from the coolant temperature sensor allows the ECM to optimize engine performance, fuel economy, and emissions. Each Walker sensor is engineered to match OE specifications for resistance values, thermal response, and signal output, ensuring reliable integration with factory systems. Built with durable, heat-resistant materials, these sensors are made to withstand constant exposure to coolant, vibration, and extreme temperature swings. A direct-fit design ensures easy installation with no modifications required. Whether replacing a failed sensor or addressing a check engine light, Walker Products delivers the quality and accuracy technicians trust.
