Global Parts 1712623 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Volkswagen and Audi

Global Parts 1712623 is an engine coolant temperature sensor used to send coolant 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 compressor damage.

• Engine coolant temperature sensor for temperature signal input to the ECM
• 2-terminal design on listed Volkswagen and Audi applications
• Used on heater core locations for select Volkswagen Jetta applications
• Direct replacement for common import cooling-system sensor applications
• Cross-references SU4336 and TS360 for the same application

What This Sensor Helps Address

• Incorrect coolant temperature readings at the ECM
• A/C compressor shutdown caused by faulty temperature input
• Hard starting or poor warm-up behavior tied to sensor signal issues
• Cooling-system warning lights triggered by a failed sensor
• Driveability problems on Volkswagen Jetta, Golf, Passat, EuroVan, Corrado, and Audi A4 applications

Installation Notes and Tips

Verify the connector style and terminal count before installation. Match the sensor location and application notes exactly, especially for the 1999 and 1990-1992 Volkswagen Jetta heater core applications. Confirm the replacement part number 1712623 against the original sensor and vehicle service information before installation.

Quality Assurance

Global Parts 1712623 is built for listed Volkswagen and Audi cooling-system applications and follows the original function of the coolant temperature signal switch used by the ECM and A/C control strategy.
