Walker 211-2064 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker 211-2064 is an engine coolant temperature sensor built to send real-time coolant temperature data to the ECM. It supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan control for accurate engine management. This Sensor Only line focuses on OE-style fitment and signal accuracy for service replacement work.

Compatible with 2011-2015 Chevrolet Volt and 2014-2016 Cadillac ELR applications, Walker 211-2064 is a direct-fit replacement for radiator-mounted coolant temperature sensor service. It uses a female circular connector with 2 pin terminals and no wiring harness included.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• OE-matched resistance values, thermal response, and signal output
• Direct-fit design for factory-style installation
• Heat-resistant construction for coolant and vibration exposure
• Female circular connector with 2 pin terminals
• Sensor only; wiring harness not included

Sensor Line Details

Walker Products Sensor Only parts are built for straightforward replacement service where the original sensor is the point of failure. Part number 211-2064 follows OE specifications so the ECM receives the temperature data it expects, helping maintain proper engine operation on Chevrolet Volt and Cadillac ELR models. This part cross-references Four Seasons 55176 and Facet 7.3387 for the same application.

Common Problems This Part Can Address

• Check engine light related to coolant temperature sensor performance
• Incorrect coolant temperature readings sent to the ECM
• Hard cold starts or poor cold-start fuel enrichment
• Cooling fan operation issues tied to temperature input
• Fuel economy or drivability concerns caused by inaccurate temperature data

Installation Notes

Fits 2011-2015 Chevrolet Volt, location-radiator; sensor only. Fits 2014-2016 Cadillac ELR, tin terminal pins; sensor only. Verify connector shape, terminal count, and mounting location before installation. Because the wiring harness is not included, reuse the existing harness connection when serviceable and confirm the terminals are clean and secure.

Quality Assurance

Walker Products engineers this coolant temperature sensor to match OE resistance, response, and output characteristics for reliable integration with factory engine management systems. Durable materials are selected to handle continuous coolant exposure, vibration, and temperature cycling.
