I have nearly removed the alternator from my 405 STI for some TLC from an auto leckky. (It's only wacking out 13V max).
Having a few problems though just as the daylight was disappearing today. The last bolt the alternator swivels on seems to be a pain in the rectum to get out.
Looks like I need to remove the belt auto tensioner assembly to allow the 22mm bolt to unscrew fully.
Is this the case? Hope not
The allen key studs are very tight so I'm not looking forward to bad news
