I've done loads of belts in my time and must say when I did the belt change on the Golf it was a nightmare. No access, at all, you have to work around an engine mounting that doesn't come off the engine although you have to remove it.

Not nice, worth paying unless your a nutter like me... but you'll only do it once !

You'll also need;

Crank locking tool
Cam locking pin
Belt tensioner plunger retaing peg
Tensioner spanner.

Again not nice, but a good character building challenge, especially the hidden engine mounting bolt, that is great fun.
