I've done the water pump on mine so know how tight it is for access behind there. The only thing I'm not looking forward to is the hose clips, the rest shouldn't be too bad at all really.

I had a pair of pipe grips to get in and have them, you can get ratchet pliers which are pretty good for them!

best thing for the hose clips are waterpump pliers, makes it so much easier to get them off.

I'm sure you know this but make sure you bleed out the coolant system once you've put the new thermostat in

All in hand buddy, cheers. Had to bleed it after replacing a coolant hose, and then again after doing the water pump.
