Walker 211-2039 Engine Coolant Temperature Sensor - Radiator
Engine Coolant Temperature Sensor Overview
Walker Products Sensor Only engine coolant temperature sensor 211-2039 provides the ECM with live coolant temperature data for accurate fuel delivery, ignition timing, cold-start enrichment, and cooling fan control. This direct-fit replacement is built for Ford and Lincoln applications that need a precise coolant temperature signal.
Compatible With 2020-2023 Ford Escape, 2020-2023 Ford Explorer, 2021-2023 Ford Bronco Sport, 2021-2023 Ford Mustang Mach-E, 2021-2023 Lincoln Corsair, 2022-2023 Lincoln Aviator, and 2023 Ford F-250 Super Duty or F-350 Super Duty radiator applications. Part number 211-2039 is also referenced for OE-style replacement needs.
Key Features
- Engine coolant temperature sensor for ECM temperature input
- Direct-fit design for factory-style installation
- Matches OE resistance values, thermal response, and signal output
- Heat-resistant construction for coolant, vibration, and temperature cycling
- 2-terminal pin design with female rectangle connector
- Wiring harness not included
Detailed Description
Walker Products Sensor Only line focuses on replacement sensors engineered for accurate electrical communication with factory systems. This coolant temperature sensor is designed to report coolant temperature changes quickly and consistently so the ECM can adjust engine operation as conditions change. The result is stable temperature feedback for drivability, emissions control, and fan operation on Ford Escape, Ford Explorer, Ford Bronco Sport, Ford Mustang Mach-E, and select Lincoln models.
Built to OE specifications, 211-2039 uses a 2-pin female rectangle connector and pin terminals for a factory-style connection. The sensor body is made from durable, heat-resistant materials to handle continuous exposure to coolant and engine bay heat. This part cross-references GK2Z12A648A for the same application.
Common Problems This Sensor Can Address
- Check engine light related to coolant temperature signal faults
- Incorrect fuel mixture during cold starts
- Delayed or inconsistent radiator fan operation
- Poor idle quality after warm-up
- Temperature reading errors reported by the ECM
Installation Notes and Tips
Verify connector shape, terminal count, and sensor location before installation. This part uses a female rectangle connector with two pin terminals and does not include a wiring harness. Confirm the application location on the vehicle, especially for 2023 Ford F-250 Super Duty and F-350 Super Duty radiator use and 2022-2023 Lincoln Aviator engine coolant hose placement.
For best results, inspect the connector and surrounding cooling system components for corrosion, damaged terminals, or coolant contamination before installing the new sensor. Clear diagnostic trouble codes after replacement and confirm the ECM receives a stable temperature signal.
Quality Assurance
Walker Products designs this sensor to match OE specifications for resistance, thermal response, and signal output, supporting reliable integration with factory engine management systems. The Sensor Only product line is built for accurate replacement of failed coolant temperature sensors in Ford and Lincoln cooling system applications.
