Global Parts 1711697 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Global Parts 1711697 is an engine coolant temperature sensor for vehicles that rely on accurate coolant feedback to the engine management system. It helps the ECM monitor coolant temperature and, on applicable platforms, manage A/C operation to reduce the risk of compressor damage.

Compatible With Chevrolet Express, GMC Savana, Silverado, Sierra, Buick, Cadillac, Pontiac, and other GM and Isuzu applications listed below, this sensor is a direct-fit service part for oval-connector, 3/8-18 thread, 2-terminal applications.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Oval connector, 3/8-18 thread, 2-terminal design
• Supports engine management and A/C control functions on listed vehicles
• Direct replacement for many GM, Isuzu, and Honda Passport applications
• Part number 1711697 for catalog and service matching

Detailed Description

This Global Parts coolant temperature sensor is built for vehicles that use coolant temperature data to regulate engine operation and climate-control logic. On modern systems, the ECM uses this signal to manage A/C operation; on earlier vehicles, the circuit can directly switch the compressor off to help prevent compressor failure. Part number 1711697 is listed across a wide range of Chevrolet Express 1500/2500/3500, GMC Savana 1500/2500/3500, Silverado 1500/2500 HD/3500 HD, Sierra 1500/2500 HD/3500 HD, and many Buick, Cadillac, Pontiac, Isuzu, and related platforms.

This part cross-references Standard Ignition TX3 for the same application.

What It Helps Address

• Incorrect coolant temperature readings at the ECM
• A/C compressor cycling concerns tied to temperature input
• Hard starting or poor warm-up behavior related to sensor signal errors
• Cooling system warning lights or diagnostic trouble codes
• Driveability issues on GM truck, van, and passenger-car applications

Installation Notes and Tips

Verify the connector style, thread size, and terminal count before installation. Confirm the vehicle listing by year, make, and model, since fitment varies by platform and engine configuration. For best results, inspect the connector and wiring for corrosion or damage before replacing the sensor.
