I replaced a 2003 Chevy Venture thermostat once before. It is buried on the top right side of the engine under the throttle assembly. You can see the thermostat cover by following the 2 inch black tube from the top of the radiator to it. It is easy to replace one you remove the throttle assembly which is very difficult to do, especially if you are not familiar with engine repairs. This is not a four screws and your done job. Take it to a mechanic if you are unsure. Luckily, I had a mechanic who helped me when I did it!
