Hello, from Memphis, TN.

Please do like Blindboy said in previous post to your thread, (post a picture of exact part you need). I am confident I can get your tensioner bolts and send them to you in Alabama.

Those bolts are expensive from Volvo and not too sturdy.

I always loosen everything up and tension the belt with a pry bar - not TOO tight.

Then I snug up the tensioner and tighten the other mounting bolts, holding tension all the time.

Two of out used 740s didn't even have the tension bolts when we bought them - I think they get broken when people try to use them when one of the mounting bolts are still too tight.

Dear Hoola,

Hope you're well. I'm pretty sure that belt tensioners - a unit that includes the arm, the short bolt (which goes through the arm), and the long (tensioning) bolt (which goes through the head of the short bolt) - are "dealer-only" parts.

A salvage yard should have these tensioners, as they were used on 940s and 740s (and possibly 240s). You will need to specify which tensioner you need: alternator, power steering, or air conditioning compressor, as well as the year and model.

The long (tensioning) bolt can be bought at any hardware store, that stocks metric fasteners. I believe it is M6 x 90 mm long (3.5"), so it is best to buy a 100mm (4") bolt and cut-off 10mm (3/8").

Hope this helps.

Yours faithfully,

Spook

Pretty sure you have to buy the whole assembly, or junkyard search. Pretty common part.
