Re: Changing a starter motor
I recently changed one on a 16V. It's held with 4 M10 bolts, two of which you can only reach from above, one you can get to from above or below and one you can only get to from below. You'll need a 13mm socket, various extention bars and a 13mm spanner (one of those ratheting ones would probably be best). You'll also need a 10mm to undo the smaller contact stud nut. Best undo the connections first.
I had the battery and battery tray out when I did mine and it helped get to the upper bolts. One is tucked away behind the block; you can't see it but you can get a spanner in there.
You have to take the front section of the ehaust off to get the starter out from below. I unhooked the hangers and undid/snapped the studs on the bottom of the manifold, then lowered it and pushed it to one side (after removing the ally protecting plate).
It's not a fun job, unless you compare it with changing the clutch master cylinder! I found the worst part was trying to hold the replacement starter in position while getting the first nut started. An assistant might be handy for that.
If yours is an 8V, disregard all that and wait for advice someone who knows!
