The Thermostat on a 2000 Chevy Venture is located on the drivers side of the engine, it is mounted under the throttle-body of the fuel-air intake, u can follow the hose up to it, I have changed mine two time, although the throttle-body must be removed to access the Thermostat, and there are only three screws holding the thermostat housing on, it is somewhat hard to get at and I suggest that only someone who is familiar with working on cars try it.
