Detailed Description

The Hella 009107271 is an engine coolant temperature sensor used to report coolant temperature to the vehicle control system. Accurate temperature input is important for fuel delivery, idle quality, cooling fan operation, and overall engine management. This sensor is specified with a 12V rating, two electrical connectors, and an NTC sensing element, making it a direct-fit style replacement for many GM platforms.

Fitment includes 2018-2024 Buick Enclave, 2018-2023 Chevrolet Traverse, 2010-2021 Chevrolet Camaro, 2011-2020 Cadillac Escalade, 1999-2018 Chevrolet Silverado 1500, and 1999-2018 GMC Sierra 1500. It also covers many other Chevrolet, GMC, Cadillac, Buick, Pontiac, Saturn, Hummer, Saab, and Suzuki models listed in the fitment data.

What It Helps Solve

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting, rough idle, or poor cold-engine operation
• Cooling fan behavior that does not match engine temperature
• Check engine lights related to coolant temperature sensor performance
• Driveability issues caused by inaccurate engine temperature input

Installation Notes and Tips

Verify the connector style, thread size, and mounting type before installation. The sensor uses an M12x1.5 thread and a bolted design, so the sealing surface should be clean and free of debris before fitting the new sensor. Confirm the vehicle’s original connector count and electrical specification match the part listing, especially on Chevrolet Silverado 2500 HD, GMC Yukon, and Cadillac CTS applications.

For best results, inspect the harness connector and cooling system condition during replacement. If the old sensor has leaked coolant or shown corrosion at the terminals, address those issues before installing the new unit.

Quality Assurance

Hella is an established OE-focused automotive brand, and this sensor is built to meet the listed electrical and mounting specifications for the application. Part number 009107271 is identified with the stated resistance, connector, and seal details to support accurate replacement selection.
