Walker 211-2159 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker 211-2159 is an engine coolant temperature sensor built to report cooling-system temperature data to the ECM. For a 1995 Mercedes-Benz E300, accurate coolant temperature input supports fuel delivery, ignition timing, cold-start enrichment, and radiator fan control.

Walker Products Sensor Only line focuses on direct replacement sensors that match factory electrical characteristics for dependable signal output. This Walker 211-2159 coolant temperature sensor uses a 2-pin male connector with a rectangular connector shape and no wiring harness included.

Key Features

• Engine coolant temperature sensor for ECM temperature monitoring
• Direct-fit replacement for 1995 Mercedes-Benz E300
• 2-pin pin terminal design with rectangular male connector
• Built with heat-resistant materials for coolant and vibration exposure
• Matches OE resistance values, thermal response, and signal output
• Walker Products Sensor Only product line for sensor replacement applications

Detailed Description

This engine coolant temperature sensor sends real-time coolant temperature information to the engine control module so the system can adjust fuel injection, ignition timing, cold-start enrichment, and cooling fan operation. On the 1995 Mercedes-Benz E300, that data is critical for stable drivability and proper emissions control. Part number 211-2159 is engineered for factory-style integration and consistent electrical response.

This part cross-references Four Seasons 53015 and TYC 700050 for the same application.

Common Issues This Part Can Address

• Check engine light related to coolant temperature signal faults
• Hard starting when the engine is cold
• Incorrect fuel mixture from inaccurate temperature input
• Cooling fan operation problems tied to temperature reporting
• Poor idle quality caused by faulty ECM temperature data

Installation Notes and Tips

Verify the connector shape, terminal count, and pin style before installation. This sensor uses a rectangular male connector with two terminals and does not include a wiring harness. Confirm the cooling system is at a safe temperature before removal, and inspect the connector and surrounding harness for corrosion or damage during replacement.

Compatible With 1995 Mercedes-Benz E300, N/A. Use part number 211-2159 to confirm the correct coolant temperature sensor for your application.

Quality Assurance

Walker Products engineers this sensor to OE specifications for resistance values, thermal response, and signal output, with durable materials selected for continuous exposure to coolant, vibration, and temperature swings.
