i don't know that car specifically, but the thermostat is always at the end of the radiator hose. where it attaches to the engine. there should be a metal housing bolted to the engine that the hose runs into. the thermostat should be inside it.

See the link for a 2000 location. The 2001 procedure ought to be about the same.
