86 coupe a/c belt

[Mark Donohoe]

Great, at least I'm not missing a critical part.  I will get a new belt and report back.  I'll also try to tighten the tension with that bolt on the a/c bracket.  It's already pretty tight.  And you guys are right, that belt sure vibrates alot.  Thanks for the advice and I'll let you know what happens.

There certainly is no tensioner like that.

I'd say a good start would be to replace the belt (with a good 
euro-profile brand like Continental, might as well do all 3 at the same 
time...) and get the tension right, see if that helps.

If you think the belt is in really good shape, try tightening it at the 
AC pump adjustment.
