It's the other end of the engine to the belt, quite easy job, just undo pipes and bolts on stat housing to get at it, make sure to get a new o ring seal, should be with kit, and don't overdo the bolts upon reassembly as housing plastic can break.

When I did mine on my st170 there was no need to remove any pipes. Undo 3 torx screws, whip out old stat, slot new one in, job jobbed. Just make sure you fit the seal on the stat before it goes in, and put a bowl or something underneath the stat housing to collect lost coolant (you will get about half a litre), stick the coolant back in the header tank, 10 minute job!
