Global Parts 1712570 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for GM Applications

Global Parts 1712570 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 systems, it can directly shut off the compressor to reduce the risk of compressor failure. This part number 1712570 is a direct-fit option for select Chevrolet and GMC trucks and vans.

Key Features

• Engine coolant temperature sensor for electronic temperature feedback
• Supports ECM-controlled A/C system operation on modern vehicles
• Used in earlier systems to help prevent compressor damage
• 1/2 - 14 NPT thread design
• 3-terminal configuration
• Cross-references Four Seasons 37880 and Standard Ignition TX102 for the same application
