Detailed Description

MotoRad 1TS1056 is an engine coolant temperature sensor engineered for direct replacement service on Subaru Impreza, Subaru Legacy, and Subaru Forester applications. The sensor uses a blade terminal layout, oval connector shape, and 2-terminal female connection to match the original electrical interface used in the vehicle cooling system. The MotoRad 1TS1056 is intended for drivers and technicians replacing a worn or inaccurate coolant temperature sensor on 1990-1999 Subaru Legacy, 1993-1999 Subaru Impreza, and 1998 Subaru Forester models.

This part cross-references Dorman - HELP 74023 for the same application. It also cross-references OE-style numbers including 22630AA040 and 22630AA041.

What It Helps Fix

  • Incorrect coolant temperature readings
  • Check engine light concerns related to temperature signal faults
  • Hard starting or rough running caused by bad temperature input
  • Cooling fan control issues tied to sensor signal errors
  • Driveability problems from an aging or heat-damaged sensor

Installation Notes and Tips

Verify connector shape, terminal count, and sensor location before installation. This sensor uses a female oval connector with blade terminals and does not include a wiring harness. Confirm the vehicle application against the listed Subaru fitment before replacing the original part.
