Global Parts 1712635 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Volvo and Porsche

Global Parts 1712635 is an engine coolant temperature sensor that sends temperature feedback 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 failure. Compatible With select Porsche 928 and Volvo models with an M12 x 1.5 thread and 2 terminals.

Key Features

• Engine coolant temperature sensor for temperature signal input to the ECM
• Supports A/C control logic on modern vehicle systems
• Used in earlier systems to help shut the compressor off when needed
• M12 x 1.5 thread and 2-terminal configuration on listed applications
• Global Parts part number 1712635
• Cross-references Four Seasons 37886 and Standard Ignition TX39 for the same application

Detailed Description

This coolant temperature sensor is built for specific Porsche 928 and Volvo applications where accurate coolant temperature feedback is required for engine management and climate-control operation. Global Parts 1712635 is listed for 1989-1991 and 1993-1995 Porsche 928, plus 1986-1993 Volvo 240, 760, 780, 740, 850, 940, and 960 applications with the noted thread and terminal configuration. The sensor helps the ECM read engine coolant temperature so the vehicle can respond appropriately to operating conditions.

What It Helps Address

• Incorrect coolant temperature readings at the ECM
• A/C compressor shutoff or control issues tied to temperature input
• Driveability problems caused by inaccurate engine temperature data
• Cooling-system warning or sensor-related fault conditions
• Hard starting or poor warm-up behavior related to temperature signal errors

Installation Notes and Tips

• Verify the vehicle uses an M12 x 1.5 thread and 2 terminals before ordering.
• Confirm the application against the listed fitment for your exact year and model.
• Inspect the connector and wiring for corrosion or damage during replacement.
• Use the sensor location specified by the vehicle service information for installation.

Quality Assurance

Global Parts 1712635 is an OE-style replacement sensor for listed Porsche and Volvo applications, built to provide the coolant temperature feedback required by the engine management system.
