Global Parts 1712579 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for GM Trucks

Global Parts 1712579 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 applications, it can directly switch the compressor off to help prevent failure.

• Engine coolant temperature sensor for GM truck and SUV applications
• 1/2 - 14 NPTF thread with 2-terminal design on listed applications
• Supports engine management input for temperature-based control
• Direct replacement style for service and repair work
• Cross-references Standard Ignition TX110 and aftermarket numbers 213-1526, SU1512, WT5120

Detailed Fitment and Function

This Global Parts 1712579 sensor is used in temperature monitoring circuits on select Chevrolet and GMC vehicles, including Silverado 2500 HD, Silverado 3500, Sierra 2500 HD, Sierra 3500, Avalanche 2500, Suburban 2500, and Yukon XL 2500 applications. It is a practical replacement for vehicles that rely on coolant temperature input for ECM-controlled A/C logic and related engine management functions.
