Global Parts 1712631 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Volkswagen and Audi

Global Parts 1712631 is an engine coolant temperature sensor that sends temperature feedback to the engine management system. In modern vehicles, that signal can also help the ECM manage A/C operation; in earlier systems, it can be used to shut the compressor off and reduce the risk of compressor damage. This part is a direct-fit style replacement for select Volkswagen Golf and Audi A8 applications.

Detailed Product Information

Global Parts 1712631 is built for vehicles that rely on coolant temperature input to manage engine operation and climate control logic. If the sensor signal is inaccurate or intermittent, the ECM may receive incorrect temperature data, which can affect drivability and system control. This part cross-references Four Seasons 70033 for the same application.

Common Issues This Sensor Can Address

• Incorrect coolant temperature readings at the ECM
• Erratic A/C compressor control tied to temperature input
• Hard starting or poor cold-engine fuel management caused by bad temperature data
• Cooling system warning behavior related to sensor signal faults
• Check engine light conditions associated with coolant temperature sensor failure

Installation Notes and Tips

Verify the connector style, thread size, and terminal count before installation. Confirm the vehicle application against the listed fitment for 1999-2001 Volkswagen Golf, 1997-1999 Audi A8, and 1997-1999 Audi A8 Quattro. Inspect the connector and wiring for corrosion or damage before replacing the sensor.
