Where is thermostat located on a 2005 gmc envoy?

On a 2005 GMC Envoy, the thermostat is typically located near the engine, specifically at the engine's upper radiator hose connection to the engine block. To access it, you may need to remove the upper radiator hose and possibly other components, as it's usually housed within a housing that can be bolted to the engine. It's advisable to consult a repair manual for detailed instructions and diagrams for your specific model.
