Detailed Description

This Global Parts coolant temp sensor is built for radiator-mounted applications and is engineered to provide the ECM with accurate coolant temperature input. On vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade, correct temperature reporting is important for cooling system control and engine protection. Part number 1814558 is a direct replacement sensor for the listed GM fitments and cross-references 5S17528 and 12707289 for the same application.

Compatible With 2024-2025 Chevrolet Silverado EV, 2023-2025 Chevrolet Trailblazer, 2021-2025 GMC Yukon, 2022-2025 GMC Yukon XL, 2023-2024 Cadillac CT4, 2023-2024 Cadillac CT5, 2022-2024 Cadillac Escalade, 2022-2024 Cadillac Escalade ESV, 2023-2024 Cadillac LYRIQ, 2023-2024 Cadillac XT4, 2023-2024 Cadillac XT5, 2023-2024 Cadillac XT6, 2023-2024 Chevrolet Blazer, 2024 Chevrolet Blazer EV, 2023-2024 Chevrolet Colorado, 2023-2024 Chevrolet Corvette, 2024 Chevrolet Equinox EV, 2022-2024 Chevrolet Silverado 1500, 2023-2024 Chevrolet Tahoe, 2024 Chevrolet Traverse, 2022-2024 GMC Hummer EV Pickup, 2021-2024 GMC Sierra 1500, 2022 Chevrolet Silverado 1500 LTD, 2022 Chevrolet Silverado 1500 Nueva, 2022 GMC Sierra 1500 Limited, 2020-2021 Buick Encore GX, and 2021 Buick Envision. Additional listed applications include 2021 Cadillac Escalade and Escalade ESV with clips into heater hoses, and 2021 Chevrolet Silverado 1500 in hose-mounted service.

What It Helps Address

  • Incorrect coolant temperature readings at the ECM
  • Cooling fan or cooling strategy concerns tied to sensor input
  • Overheating issues caused by a failing temperature sensor
  • Check engine concerns related to coolant temperature signal faults
  • Hard starting or drivability issues linked to inaccurate temperature data

Installation Notes and Tips

Verify the connector style, terminal count, and mounting location before installation. This sensor uses a female oval connector with two male blade terminals, and the listed fitments place it on the radiator for most applications. Confirm the exact vehicle year, make, and model, since some 2021 Cadillac and Chevrolet applications use heater-hose or in-hose mounting instead of radiator mounting.

Quality Assurance

Global Parts designs this coolant temperature sensor as an OE-spec replacement for the listed applications. It is intended to restore proper coolant temperature signal delivery to the ECM on supported Chevrolet, GMC, Buick, and Cadillac vehicles, including Silverado 1500, Sierra 1500, and Escalade platforms.
