Hi:

First you'll need to drain the coolant from the radiator. Next, follow the upper radiator hose back to the engine. Where the hose attaches is the thermostat housing. First remove the hose, then the two bolts holding the housing on. Under the housing is the thermostat. Remove it, replace it in the same direction and reverse the steps ending with adding the coolant.

If you run into trouble, let me know. I'll get back to you ASAP.
