TL;DR Summary
Coolant temperature sensors help your GM vehicle monitor engine temperature and support fuel, fan, and warning-system decisions. OEM sensors help preserve correct readings, sealing, and connector fit.
Overview
A coolant temperature sensor helps the vehicle understand engine temperature. When it fails or reads incorrectly, it may cause warning lights, an inaccurate temperature display, cooling fan issues, or poor cold-start behavior. Van Chevrolet GM Parts Center offers genuine GM cooling sensors designed for compatible GM vehicles.

- OEM sensors help match electrical readings and physical fit.
- Engine and sensor-location details matter for fitment.
FAQ Section
What symptoms can a bad coolant temperature sensor cause?
Possible symptoms include warning lights, inaccurate temperature readings, fan operation concerns, or poor running when cold.
Is this the same as a thermostat?
No. The sensor reports temperature information, while the thermostat controls coolant flow.
Should I replace the seal with the sensor?
If the sensor uses a separate seal or O-ring, replacing it during service is often appropriate.
