Question alternator belts loose

how to tighten , looks like there is a 13mm adjuster bolt but do you have to loosen some other(s) as well before adjusting? if so where are they?
thanks in advance - my belts are squealing like mad and it's frankly, well, attracting stares..

There are two bolts that will need to be loosened prior to tightening that 13 mm tensioner bolt. They are the two bolts that hold the alternator on. I believe they are 17 mm. Look at where the tensioner "pulls" on alternator at the pulley end and you should be able to see the end of the upper bolt. The other should be underneath the alternator. Loosen them up and tighten the 13 mm tensioner and then tighten the 17 mm bolts back up and you should be good to go.

success!

jim. thanks for your help - belts not squealing like a dying pig anymore! for your info only had to loosen one 17mm bolt attached to the back end of the through bolt which leads to to the tension adjuster. made it a whole lot easier. for access removed the plastic part of the intake going from the air cleaner to the turbo and then could fit an open end wrench over the bolt and the whole job can be accormplished from the top.

on another note while i was at it took 3 clockwise turns on the bowden cable adjuster on top of the valve cover. trans shifts smoother now than it has in 7 years!! i'm totally psyched no hard shifts anymore. (only took me 85k miles of driving to figure it out...doh..)
