Walker Products 211-1082 Engine Coolant Temperature Sender

The Walker Products 211-1082 is an OE replacement Engine Coolant Temperature (ECT) Sender engineered to measure engine coolant temperature and transmit that data to the ECU or instrument cluster. This temperature signal plays a critical role in controlling engine warm-up, cooling fan activation, fuel injection timing, and emission system readiness.

The sender operates by varying its electrical resistance in response to coolant temperature changes, feeding real-time data to the onboard computer. The computer uses this input to calculate the correct fuel delivery, optimize ignition timing, and manage cold-start enrichment. A failed or degraded sender can cause inaccurate temperature gauge readings, false dashboard behavior, poor fuel economy, or a steady check engine light.

Key Features:

• OE replacement design engineered to match original resistance values, thermal response curves, and mounting thread type
• Threads directly into the factory port — typically located in the engine block, thermostat housing, or intake manifold
• Built from high-temperature, corrosion-resistant materials to withstand pressurized coolant, vibration, and thermal cycling
• Direct-fit installation with no modifications required — connects seamlessly to the vehicle's factory wiring harness
• Manufactured and tested to meet or exceed OEM specifications for fit, form, and function
• Helps restore accurate temperature monitoring, correct gauge behavior, and proper engine control logic

Walker Products has been supplying the automotive aftermarket since 1946 and is one of the largest privately owned manufacturers of fuel system components and engine sensors. As an ISO 9001/IATF 16949 certified manufacturer, every sensor is quality inspected and tested before shipment. Recommended service interval for coolant temperature senders is every 25,000 to 35,000 miles.
