Walker 211-2053 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for GM Applications

Walker Products 211-2053 is an engine coolant temperature sensor built to deliver accurate coolant temperature data to the ECM. With a 2-terminal blade connection, oblong female connector, and direct-fit sensor-only design, it supports precise engine management on select Buick, Cadillac, Chevrolet, and GMC vehicles.

Walker Sensor Only parts focus on the sensing element itself, making them a practical OE-style replacement when the original coolant temperature sensor has failed or is sending incorrect readings. Part number 211-2053 is engineered for factory-style resistance values, thermal response, and signal output.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Blade terminal type with 2 terminals
• Oblong female connector
• Sensor only; wiring harness not included
• Heat-resistant construction for coolant and temperature cycling exposure
• Direct-fit replacement for select GM vehicles

Detailed Description

This Walker engine coolant temperature sensor helps the ECM monitor cooling-system temperature so it can manage fuel injection, ignition timing, cold start enrichment, and fan operation. Accurate coolant temperature data is important for stable drivability, fuel economy, and emissions control. Part number 211-2053 is built to match OE specifications for resistance and signal response, helping restore proper sensor feedback on vehicles such as the Chevrolet Blazer, Cadillac XT5, and GMC Acadia.

This part cross-references Facet 7.3403 for the same application.

Common Issues This Sensor Can Help Address

• Check engine light related to coolant temperature signal faults
• Incorrect coolant temperature readings at the ECM
• Hard cold starts or poor cold-start fuel delivery
• Cooling fan operation problems caused by inaccurate temperature input
• Rough engine performance tied to faulty temperature data

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. This sensor uses a blade terminal, oblong female connector, and no wiring harness. Confirm the application by year, make, model, and sensor location, since fitment includes engine block, coolant pipe, timing cover, and engine-mounted positions depending on the vehicle. Compatible applications include Fits 2021-2023 Buick Encore GX, N/A; Fits 2022-2023 Buick Envision, N/A; Fits 2020-2023 Cadillac CT5, N/A; and Fits 2021-2023 Chevrolet Blazer, N/A.

Quality Assurance

Walker Products engineers this sensor to OE-style resistance values, thermal response, and output characteristics for reliable integration with factory systems. Part number 211-2053 is built with durable, heat-resistant materials for exposure to coolant, vibration, and repeated temperature swings.
