Walker 211-2186 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Mercedes-Benz

Walker 211-2186 is a Sensor Only engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. For a 1995 Mercedes-Benz S350, accurate temperature input supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation.

The Sensor Only line focuses on direct replacement sensors engineered to match OE resistance values, thermal response, and signal output. Walker 211-2186 uses a 2-terminal bullet connection with a rectangular male connector and no wiring harness included.

Key Features

• Engine coolant temperature sensor for ECM temperature reporting
• Direct-fit replacement for 1995 Mercedes-Benz S350, sensor only
• 2 terminal bullet design with rectangular male connector
• Built with heat-resistant materials for coolant and vibration exposure
• Matches OE-style resistance, response, and signal characteristics

Detailed Description

Walker 211-2186 is designed for vehicles that rely on precise coolant temperature input to manage drivability and emissions. In a 1995 Mercedes-Benz S350, the sensor helps the ECM interpret engine temperature so it can adjust fuel injection, ignition timing, and fan control based on current operating conditions. This part number, 211-2186, is a direct-fit replacement for technicians and owners addressing temperature-related fault codes or inaccurate gauge and ECM readings.

This part cross-references Four Seasons 53014 for the same application.

What It Helps Address

• Check engine light related to coolant temperature signal faults
• Hard cold starts or extended warm-up behavior
• Incorrect fuel mixture caused by inaccurate temperature input
• Cooling fan operation issues tied to sensor data
• Poor idle quality when the ECM receives incorrect coolant readings

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. This Walker 211-2186 sensor uses a rectangular male connector with bullet terminals and does not include a wiring harness. Confirm the cooling system is at a safe temperature and inspect the connector and wiring for corrosion or damage before connecting the new sensor.

Quality Assurance

Walker Products engineers these coolant temperature sensors to OE specifications for resistance, thermal response, and output signal, with durable materials selected for continuous exposure to coolant, vibration, and temperature swings. Walker 211-2186 is built for reliable integration with factory engine management systems.
