Global Parts 1712640 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Global Parts 1712640 is an engine coolant temperature sensor for vehicles that rely on accurate coolant feedback for engine and A/C control. It is used in applications where the ECM monitors coolant temperature to manage system operation and protect components.

• Engine coolant temperature sensor for temperature feedback to the engine management system
• Supports ECM-controlled A/C operation on modern vehicles
• Used in earlier applications to help shut off the compressor and reduce failure risk
• Direct-fit coverage for select Chevrolet, GMC, Mercedes-Benz, Buick, Cadillac, Chrysler, and Dodge models
• Cross-reference: Four Seasons 37839

Detailed Fitment and Function

This Global Parts 1712640 sensor is built for vehicles that use a 2-terminal coolant temperature sensor or engine block-mounted coolant temperature input. It is compatible with applications such as Chevrolet Malibu, Chevrolet Spark, Chevrolet Trailblazer, Chevrolet Colorado, GMC Canyon, and Mercedes-Benz models including E-Class, S-Class, SLK, ML, and CL platforms. This part cross-references Four Seasons 37839 for the same application.

By sending coolant temperature data to the ECM, the sensor helps the vehicle manage fuel, idle, cooling fan strategy, and air conditioning logic. For Mercedes-Benz and GM applications listed here, accurate temperature input is critical for stable drivability and proper thermal control. Part number 1712640 is also referenced by 5425118, SU6054, SW11544, TS615, and WT7262.

What This Part Helps Address

• Incorrect coolant temperature readings
• Erratic A/C compressor control
• Cooling system warning lights
• Poor engine management data from the coolant circuit
• Driveability issues tied to temperature input faults

Installation Notes

Verify the connector style, terminal count, and mounting location before installation. Fitment includes engine block and N/A-position applications, so confirm the exact sensor style against the original part on your vehicle. For best results, compare the old sensor to the replacement before installation on Chevrolet Malibu, Chevrolet Spark, and Mercedes-Benz applications.

Quality Assurance

Global Parts 1712640 is an OE-style replacement sensor designed for the listed applications and temperature-control functions.
