Well, I grabbed the 13mm+a longer bar &Carefully tightened the belt. Probably not enough because noise stays so I`ll redo it tomorrow.

Usually after cold starts, I started hearing this sh!t squeal again. (for up to a minute). Higher loads (Using heater+fogs+radio,etc) can still trigger same sounds while car`s in motion at lower rpm (any speed, obviously) -->

The belt is definitely not tight. A closer look is telling me it is not in best shape either... WTHeck. (After `cracking up` at multiple spots, did it go elongated enough to become loose??)
I`ll be trying to find a Seller (Volvoparts,tasca,Ipd dont have it)... an 85 D Volvo is almost always non-existent in most of the search boxes.

How important is it to use OE? Sayings about Volvo quality are not always true but This same exact belt have already had its side/edge damages present years ago but never gave up really so i left it alone...by now it does look more disintegrated.

Written on belt: `VOLVO 966 894 9,5 x 750 La Made in Germany 6135`
I`m sure Volvo used same belt on many of their other models also.
Thanks for suggestions. I attached a few fresh pictures to illustrate this cr@p.
