How do you replace the thermostat located on a 1999 Chevy Malibu LS 3.1L V6?

It should be at the end of the big radiator hose on top of the engine but if your car is over heating its probably the head or intake gasket leaking. look in your overflow tank and see if its bubbling or pushing out fluid with cap of or blowing white smoke out exhaust.
