Engine Coolant Temperature Sensor for GM SUVs
Global Parts 1712578 is an engine coolant temperature sensor used to send temperature feedback to the engine management system. On modern vehicles, that signal helps the ECM manage A/C operation; on earlier systems, it can directly shut the compressor off to help prevent failure. This Global Parts 1712578 sensor is a direct-fit option for select Buick, Chevrolet, GMC, Isuzu, Oldsmobile, and Saab applications.
Key Features
- Engine coolant temperature sensor for temperature signal feedback
- M12 x 1.75 thread with 2-terminal electrical connection
- Designed for select GM and related platform vehicles
- Cross-references Standard Ignition TX108
- Interchanges with 213-963, 213963, SU1485, and WT5122
