Engine Coolant Temperature Sensor for Mercedes-Benz

Global Parts 1712656 is an engine coolant temperature sensor for Mercedes-Benz applications that use a 2-terminal, M14 x 1.5 thread design. It provides temperature feedback to the engine management system and, on vehicles with automatic climate control, helps the ECM manage A/C operation based on coolant temperature.

Fits 1990-2002 Mercedes-Benz models listed below, including Mercedes-Benz SL600, S500, and S320 applications with the specified thermostat housing or threaded sensor setup. Part number 1712656 is also referenced for select OE-style replacement needs.

Key Features

  • Engine coolant temperature sensor for engine management input
  • 2-terminal electrical connection
  • M14 x 1.5 thread size
  • Used on applications with automatic climate control where noted
  • Located on the thermostat housing on listed fitments
  • Global Parts part number 1712656

Detailed Description

This coolant temperature sensor monitors engine coolant temperature and sends that information to the ECM. On modern vehicles, that signal can influence engine control and A/C operation; on earlier vehicles, it can directly help prevent compressor damage by switching the compressor off when temperature conditions require it. This part cross-references SU7687 and TS529 for the same application.

Compatible With Mercedes-Benz SL600, S320, S420, S500, S600, SL500, E420, C220, 300D, 300SL, 400E, 400SEL, 500E, 500SEC, 500SEL, 500SL, 600SEC, 600SEL, 400SE, and 420SEL applications listed in the fitment data. Use part number 1712656 when matching the connector style, thread size, and thermostat housing location.

Common Replacement Reasons

  • Incorrect coolant temperature readings
  • Hard starting or poor warm-up behavior tied to temperature input
  • A/C control issues related to coolant temperature feedback
  • Check engine light from a faulty coolant temperature signal
  • Sensor leakage or connector-related failure at the thermostat housing

Installation Notes

Verify the connector style, 2-terminal layout, and M14 x 1.5 thread before installation. Confirm the sensor location on the thermostat housing and compare the removed part to the vehicle listing for your Mercedes-Benz model and year. Clear diagnostic codes after installation and check for proper coolant temperature readings.

Quality Assurance

Global Parts 1712656 is built for the listed Mercedes-Benz applications and follows the fitment and configuration details provided in the catalog data.
