Engine Cooling problem

Need to replace the thermostat on my 2002 Buick Rendezvous. I would like to know what I need to remove and how to remove it so as to have access to the the two thermostat housing bolts?

Drain the coolant until the coolant level is below the thermostat.
Remove the crossover exhaust pipe.
Remove the radiator hose from the thermostat housing.
Remove the thermostat housing bolts and clean any sealer from the bolt threads.
