Global Parts 1712496 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Global Parts 1712496 is an engine coolant temperature sensor for vehicles that rely on accurate coolant temperature feedback for engine management and A/C control. It is a direct-fit style replacement for a wide range of Chevrolet, GMC, Cadillac, and select Buick applications, including Silverado 1500, Sierra 1500, Tahoe, Yukon, and Escalade models.

This part cross-references Standard Ignition TX247 for the same application.

Key Features

• Engine coolant temperature sensor for engine management input
• Supports ECM temperature feedback used in modern A/C control strategies
• Direct replacement for multiple GM applications
• Part number 1712496 for catalog and service matching
• Compatible with select M12 x 1.5 thread, 2-terminal applications

Detailed Description

The Global Parts 1712496 coolant temperature sensor reports engine coolant temperature to the ECM so the vehicle can manage fuel strategy, cooling fan operation, and air conditioning logic. On newer GM platforms, this signal is used by the engine control system to regulate A/C operation; on earlier designs, it was also used to shut the compressor off and reduce the risk of compressor damage. This makes 1712496 a practical replacement when diagnosing temperature-related drivability or HVAC concerns on Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and related models.

What It Helps Solve

• Incorrect coolant temperature readings
• Check engine lights tied to temperature sensor faults
• A/C compressor shutdown caused by bad temperature input
• Cooling fan operation issues related to ECM temperature data
• Hard starting, rich running, or poor fuel control from inaccurate sensor feedback

Installation Notes and Tips

Verify thread size, terminal count, and connector style before installation. This sensor is listed for applications with M12 x 1.5 thread and 2 terminals on select vehicles, including 2016-2021 Chevrolet Silverado 2500 HD and Silverado 3500 HD, 2016-2021 GMC Sierra 2500 HD and Sierra 3500 HD, and other GM models shown in the fitment data. Confirm the engine and model year match the catalog listing before replacing the original sensor.

Quality Assurance

Global Parts 1712496 is cataloged as an OE-style replacement sensor for GM cooling and engine management applications. It is listed under part number 1712496 for service identification and interchange matching.
