Engine Coolant Temperature Sender

Description

Walker Products Engine Coolant Temperature Senders are OE Replacement components engineered to measure engine coolant temperature and transmit that data to either the ECU or instrument cluster. This temperature input plays a critical role in controlling engine warm-up, cooling fan activation, fuel injection timing, and emission system readiness. A failing sender can result in inaccurate temperature readings, false dash gauge behavior, or improper engine control logic. Each Walker sender is manufactured to meet OE specifications for resistance values, thermal response curves, and mounting thread type. Built from high-temperature, corrosion-resistant materials, these sensors are designed to endure prolonged exposure to pressurized coolant, vibration, and thermal cycling. With an exact OE fit, Walker Coolant Temperature Senders thread directly into the original port—typically in the engine block, thermostat housing, or intake manifold—and connect seamlessly to the vehicle’s factory wiring. Whether performing a cooling system diagnostic, replacing a failed sensor, or conducting emissions-related service, Walker Coolant Temperature Senders help restore reliable temperature monitoring, improve system efficiency, and support long-term engine protection.
