Detailed Description

This coolant temp sensor is used by the vehicle’s control system to monitor engine temperature and provide the ECM with the input it needs for proper operation. On modern systems, that signal can also influence A/C control; on earlier vehicles, it was used to shut the compressor off and help prevent compressor failure. Global Parts 1712677 is listed for 1986-1993 Mercedes-Benz applications, including 300TE, 300SE, 300SEL, 300CE, 300E, 190E, 260E, 420SEL, 560SEC, 560SEL, and 560SL.

Compatible With Mercedes-Benz 300TE, 1988-1993; Mercedes-Benz 300SE, 1988-1991; Mercedes-Benz 300SEL, 1988-1991; Mercedes-Benz 300CE, 1988-1989; Mercedes-Benz 300E, 1986-1989; Mercedes-Benz 190E, 1987-1990; Mercedes-Benz 260E, 1987-1989; Mercedes-Benz 420SEL, 1986-1989; Mercedes-Benz 560SEC, 1986-1989; Mercedes-Benz 560SEL, 1986-1989; and Mercedes-Benz 560SL, 1986-1989.

What It Helps Address

  • Incorrect coolant temperature readings
  • Engine management faults tied to temperature input
  • A/C control issues related to coolant temperature signal loss
  • Compressor shutdown concerns on earlier systems
  • Driveability problems caused by inaccurate sensor feedback

Installation Notes and Tips
