Do you mean the bottom rad hose or the coolant pipe on the back of the block? I'm guessing the latter since that's the one that goes to the stat..?
If so, it's a bit of a pig tbh, you'll need to remove the stat housing from the side of the block. Pulling the driveshaft and removing the lower engine mount helps with access iirc, depends how involved you want to get and if you don't mind replacing the gearbox oil as well.
