Delphi TS10572 Engine Coolant Temperature Sensor

Delphi TS10572 Engine Coolant Temperature Sensor

The Delphi TS10572 engine coolant temperature sensor is built for direct replacement service on select Subaru applications, including Subaru Forester, Subaru Impreza, and Subaru Legacy models. It uses OE-based design and validation practices to help maintain accurate coolant temperature reporting to the engine management system.

• Engine coolant temperature sensor for threaded mounting applications
• Pin terminal design with 1 oval male connector and 2 male terminals
• 19 mm head tool size for service removal and installation
• No wiring harness included
• No thread sealer included
• Package contents: engine coolant temperature sensor

OE-Based Sensor Design

Delphi TS10572 is engineered using material selections, thickness, and construction standards based on OE specifications. Delphi applies controlled manufacturing processes and validation testing drawn from more than a century of OE experience, helping deliver consistent sensor performance for temperature monitoring in the cooling system. This part cross-references Standard Ignition TX84 for the same application.

Vehicle Fitment

• Fits 1998-1999 Subaru Forester, N/A
• Fits 1993-1999 Subaru Impreza, N/A
• Fits 1990-1999 Subaru Legacy, N/A

Common Symptoms This Sensor May Address

• Incorrect coolant temperature readings at the engine control system
• Hard starting or rough running related to temperature input errors
• Cooling fan operation concerns tied to inaccurate sensor data
• Check engine light conditions associated with coolant temperature signal faults
• Fuel mixture issues caused by unreliable engine temperature feedback

Installation Notes

Verify connector shape, terminal count, and threaded mounting style before installation. The Delphi TS10572 uses a 19 mm head tool size and does not include a wiring harness or thread sealer, so confirm the sealing method and connector condition during service. Always compare the original sensor to the replacement part before installation on Subaru Forester, Subaru Impreza, or Subaru Legacy applications.

Quality Assurance

Delphi builds this sensor using OE-oriented specifications and strict manufacturing controls to support consistent fit and function. The brand’s OE heritage and validation process are central to its aftermarket sensor design, including the TS10572.
