Walker 211-2061 Engine Coolant Temperature Sensor - Radiator
Engine Coolant Temperature Sensor Overview
Walker 211-2061 is an engine coolant temperature sensor for vehicles that use a radiator-mounted or engine cooling temperature input. It sends real-time coolant temperature data to the ECM so the system can manage fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation. This Walker Sensor Only part is built to OE resistance and signal expectations for direct replacement service.
Compatible With select 2019-2023 Buick, Cadillac, Chevrolet, and GMC applications, including Silverado 1500, Sierra 1500, Tahoe, Yukon, CT5, and Escalade platforms. The 211-2061 part number is also listed as a cross-reference to 55497116 for the same application.
Key Features
- Engine coolant temperature sensor for ECM temperature input
- OE-style resistance values, thermal response, and signal output
- Blade terminal type with 2 terminals
- Female oblong connector shape for factory-style connection
- Heat-resistant construction for coolant, vibration, and temperature cycling
- Direct-fit design for service replacement
- No mounting hardware, wiring harness, or thread sealer included
Product Details
Walker Products Sensor Only line focuses on replacement sensors that match factory electrical behavior and connector fitment. Part number 211-2061 is engineered for accurate coolant temperature reporting so the ECM can react correctly during warm-up, normal driving, and high-load operation. For vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac CT5, and Buick Encore GX, correct temperature input is critical for drivability and emissions control.
This sensor is built with durable materials to handle continuous exposure to coolant and engine bay heat. The oblong female connector and blade terminals support factory-style installation on listed applications, including radiator and engine cooling locations shown in the fitment data.
What It Helps Address
- Check engine light related to coolant temperature sensor performance
- Hard starting or rough cold starts
- Incorrect fuel mixture during warm-up
- Cooling fan operation that does not match engine temperature
- Poor fuel economy caused by inaccurate temperature input
Installation Notes
Verify connector shape, terminal count, and mounting location before installation. This part uses a female oblong connector with 2 blade terminals and does not include mounting hardware, a wiring harness, or thread sealer. Confirm the vehicle’s original sensor style and location, especially on applications listed as radiator or engine cooling positions. Fits 2021-2023 Chevrolet Silverado 1500, radiator; fits 2021-2023 GMC Sierra 1500, radiator; fits 2021-2023 Cadillac Escalade, radiator.
Quality Assurance
Walker Products designs this sensor to match OE specifications for resistance, thermal response, and output signal, supporting reliable integration with factory engine management systems. The 211-2061 is built for consistent service in demanding cooling-system environments.
