The thermostat for a 2017 Chevy Silverado is located in the thermostat housing along the lower coolant line. It is responsible for monitoring and regulating the coolant temperature in the engine. If the thermostat malfunctions, it can lead to engine overheating, potentially causing damage to the head gasket, which can be a costly repair. If the check engine light indicates an issue with the thermostat, it is crucial to address it promptly. A full replacement typically costs around $200, so delaying the repair is not advisable.
The outside temperature sensor for the 2017 Chevy Silverado can be found on the driver's side of the truck frame, right behind the front bumper.
