Walker 211-2089 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Volvo

Walker 211-2089 is a sensor-only engine coolant temperature sensor built to report cooling system temperature data to the ECM in real time. For Volvo C70, S70, S90, V70, V90, 850, and 960 applications, it supports accurate fuel delivery, ignition timing, cold start enrichment, and cooling fan control.

Sensor Line Details

Walker Products’ Sensor Only line focuses on direct replacement sensors engineered to match OE resistance values, thermal response, and signal output. That means the ECM receives the temperature information it expects from the coolant circuit, helping maintain consistent drivability and emissions control. Part number 211-2089 is built with heat-resistant materials for continuous exposure to coolant, vibration, and temperature cycling.

• Engine coolant temperature sensor for ECM temperature input
• Bullet terminal type with oblong female connector
• 2-terminal design
• Sensor only; wiring harness not included
• Direct-fit replacement for factory-style installation
• Walker 211-2089 for Volvo cooling system service
