R33 - Alternator Belt Question

[FR33KN]

Hi guys,

My R33 Gts-t is squealing bigtime on cold starts.

I searched the forum and found a thread on how to check the tension of the alternator belt. This diagram was posted.

Basically, when bolt 1 is completely tightened on, bolt 2 is still adjustable by hand? its not locking into place.

anyone have any ideas as to what to do from here? cheers.

bolt 1 does not lock bolt 2 . undo bolt one wind bolt 2 in untill belt is right tension do up belt 1.

have you positively identified it as the alt belt squeal? a lot of it is starter motor pinion squeal

hey mate thanks for your response.. Yeah I'm fairly certain it is.. without sounding too noob..which I am to turbo cars.. whats the point of unlocking the first one if the second one can just be tightened or loosened by hand regardless? is the tightness of the first one the one i should be adjusting?

cheers

As noted by lachlanw, bolt (1) locks the alternator to the bracket and bolt (2) is your belt tension adjuster.

So you'd back off bolt (1) slightly, adjust the belt tension using bolt (2), then tighten bolt (1).

Then tighten bolt (2) slightly to stop it from rattling loose.

If none of this is working, I'd guess your adjuster thread is stripped.

If so you can back off bolt (1), lever the alternator out until you get correct belt tension, then tighten bolt (1).

Thanks mate. So just to clarify, bolt 2 unscrews and screws freely by hand regardless if bolt 1 is tight or loose? is that correct?

Thanks for your help.
