Where is the thermostat on a 1995 Grand Pix 3.1 V6 engine?

The 1995 Pontiac Grand Prix 3.1L V6 engine doesn't have a thermostat in the traditional sense that you'd adjust. The thermostat is part of the engine's cooling system and is located inside the engine's water pump housing. You won't find a dial or adjustable knob; it's a mechanical component that automatically regulates coolant flow. To access it, you'll need to remove the housing.
