Just follow your top radiator hose to your engine.
The part that the hose clamps to is the thermostat housing, under this is where your thermostat is.
Just remove your hose (there will be some coolant that will leak out of this hose when disconnected) and you will see the thermostat in the housing, then remove the two bolts and pull the housing off. Take note as to how the gasket sits, I cant remember is it goes Engine, gasket, thermostat, housing or... engine, thermostat, gasket, housing. It makes a difference, I did mine backwards and it leaked. Oh and RTV sealant is your friend. Make sure you give it the full 24 hours to dry. Oh and people will say not to tighten it too much, thats what the gasket is for.... WRONG! Tighten it as much as you can, I did mine not too tight and it leaked, I had to tighten it till the bolts wouldn't turn anymore.
Well, good luck
Oh and if you havent already, you may need to change the clamps with some new ones, More adjustable ones, Mine didnt seal the hose on the housing tight enough, so I had to replace with some new ones.
