Engine Coolant Temperature Sensor for Subaru

Global Parts 1712003 is an engine coolant temperature sensor built to report coolant temperature to the engine management system. On modern vehicles, that signal helps the ECM manage A/C operation; on earlier applications, it can directly switch the compressor off to help prevent compressor damage.

  • Engine coolant temperature sensor for temperature feedback to the ECM
  • Supports A/C control logic used by the vehicle’s engine management system
  • OE-style replacement for Subaru Legacy, Forester, and Impreza applications
  • Cross-references Four Seasons 36453 and Standard Ignition TX84 for the same application
  • Part number 1712003 for fitment-based search and replacement matching

Fitment Details

  • Fits 1990-1999 Subaru Legacy, N/A. Notes: Fits vehicles with M12 x 1.5 Thread and 2 Terminals.
  • Fits 1998 Subaru Forester, N/A. Notes: Fits vehicles with M12 x 1.5 Thread and 2 Terminals.
  • Fits 1993-1998 Subaru Impreza, N/A. Notes: Fits vehicles with M12 x 1.5 Thread and 2 Terminals.

What This Sensor Helps Address

  • Incorrect coolant temperature signal to the ECM
  • A/C compressor cycling or shutdown concerns tied to temperature input
  • Hard starting or drivability issues related to coolant temperature reporting
  • Cooling system warning behavior caused by a faulty sensor signal

Installation Notes

Verify the thread size and terminal count before installation. This sensor is listed for vehicles with M12 x 1.5 thread and 2 terminals, so matching the connector and mounting style is essential for Subaru Legacy, Forester, and Impreza applications. Confirm the vehicle year and engine management setup against the fitment notes before ordering.
