Global Parts 1712550 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Mercedes-Benz

Global Parts 1712550 is an engine coolant temperature sensor for vehicles that rely on accurate coolant feedback to the engine management system. It is used on a wide range of Mercedes-Benz, INFINITI, Smart, Dodge Sprinter, and Ford applications, including many engine block and 2-terminal coolant temperature sensor locations.

This part number, 1712550, is a direct-fit style replacement for many late-model Mercedes-Benz and select import applications where coolant temperature data is used for engine control and A/C operation.

Key Features

• Engine coolant temperature sensor for ECU/ECM temperature input
• Used in engine management and A/C control strategies
• Fits engine block and 2-terminal coolant temperature sensor applications
• Cross-references Standard Ignition TX155
• Interchanges with SU13511 and WT5168

Detailed Description

Global Parts 1712550 monitors coolant temperature and sends the signal needed for proper engine control. On modern vehicles, that information helps the ECM manage cooling-related functions, while earlier systems may use the signal to switch the compressor off and reduce the risk of compressor damage. This sensor is listed for many Mercedes-Benz models, including C300, E350, GLC300, GLE350, Sprinter 2500, and Sprinter 3500, along with select INFINITI, Smart, Dodge, and Ford applications.

Compatible With 2022 Mercedes-Benz C300, engine block; 2022 Mercedes-Benz CLA250, engine block; 2021-2022 Mercedes-Benz E350, engine block; 2022 Mercedes-Benz GLC300, engine block; 2021-2022 Mercedes-Benz GLE53 AMG, engine block; and 2020-2022 Mercedes-Benz Sprinter 3500XD, engine block. Additional coverage includes many 2-terminal coolant temperature sensor applications such as 2017-2020 Mercedes-Benz AMG GT, 2016-2019 INFINITI Q50, and 2016-2017 Smart Fortwo.

What It Helps Address

• Incorrect coolant temperature readings
• Illuminated engine temperature-related warning lights
• Cooling fan or A/C control concerns tied to temperature input
• Hard starting or drivability issues caused by faulty temperature data
• Sensor failure on high-mileage Mercedes-Benz and import vehicles

Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. This part is listed for both engine block and N/A-position 2-terminal applications, so match the original sensor by year, make, model, and engine configuration. Confirm fitment carefully on Mercedes-Benz C300, E350, and Sprinter applications, since multiple coolant sensor styles appear across the same model family.

Quality Assurance

Global Parts 1712550 is cataloged as an OE-style replacement coolant temperature sensor for the listed applications. Use the vehicle fitment data and interchange references to confirm the correct part before service.
