Walker 211-2085 Engine Coolant Temperature Sensor - Radiator
Engine Coolant Temperature Sensor Overview
Walker 211-2085 is an engine coolant temperature sensor built to report cooling-system temperature data to the ECM in real time. It supports fuel delivery, ignition timing, cold-start enrichment, and radiator fan operation for accurate engine management.
Compatible with select INFINITI and Nissan applications, including 2023 INFINITI QX50 radiator, 2023 INFINITI QX55 radiator, 2022 INFINITI Q60 radiator, 2019-2021 INFINITI Q60 radiator, 2018-2023 Nissan LEAF, and 2023 Nissan Z radiator.
Key Features
- Walker Sensor Only line for direct sensor replacement
- Engine coolant temperature sensor for ECM temperature input
- Blade terminal type with 2 terminals
- Female rectangular connector for factory-style connection
- Heat-resistant construction for coolant and vibration exposure
- Direct-fit design for installation without modification
- OE-matched resistance values, thermal response, and signal output
Product Details
Walker Products 211-2085 is engineered to deliver accurate coolant temperature readings so the ECM can adjust engine operation based on current conditions. The Sensor Only product line focuses on replacement sensors that integrate with factory systems and match OE-style electrical behavior. This matters for drivers searching for a 2023 Nissan Z radiator coolant temperature sensor, a 2018-2023 Nissan LEAF engine coolant temperature sensor, or a 2022 INFINITI Q60 radiator temperature sensor replacement.
This part cross-references Standard Ignition TX318 and VEMO V38-72-0004 for the same application.
Common Issues This Sensor Can Address
- Check engine light related to coolant temperature signal faults
- Incorrect fuel mixture during cold starts
- Delayed or improper radiator fan operation
- Poor idle quality caused by inaccurate temperature input
- Reduced fuel economy from incorrect ECM temperature data
Installation Notes
Verify connector style, terminal count, and radiator location before installation. This sensor uses a blade terminal layout, a rectangular female connector, and no wiring harness is included. Confirm the vehicle’s original sensor configuration matches the listed fitment for 2023 INFINITI QX50, 2023 INFINITI QX55, 2022 INFINITI Q60, 2019-2021 INFINITI Q60, 2018-2023 Nissan LEAF, or 2023 Nissan Z.
Quality Assurance
Walker Products designs this sensor to meet OE specifications for resistance, thermal response, and signal output, supporting reliable integration with factory engine management systems.
