Where is thermostat located on 2002 Chevy Venture?

The thermostat on a 2002 Chevy Venture is located at the back of the engine, on the engine block, near the water pump. It's not easily accessible and requires removing some components to reach it. You'll likely need to consult a repair manual specific to your vehicle's engine (likely a 3.4L or 3.8L V6) for precise instructions, diagrams, and component removal order. It's usually a job best suited for someone with mechanical experience.
