The stat is a PITA. You must loosen (not not remove) the timing belt to get 
to it, along with the serp belt and serp belt tensioner. Once you see the 
whole stat housing (the pass. side water hose connects to it) you can get 
the two or three 10mm head bolts fairly easily, they are on the stat housing 
near the center of the engine. Just did one last week ;-).
