ColoradoExile Posted June 30, 2015 Share Posted June 30, 2015 (edited) As part of my timing belt change on my '99 outback 2.5 DOHC (discussed in another posting), I had to remove the tensioner for the belt that drives the A/C compressor. When I put the car back together, I noticed that the two bolts that hold this tensioner to the block did not screw all the way in (short by about .5 cm), leaving the tensioner a bit loose. I know they are the correct bolts since immediately when I removed the tensioner I put the bolts back in their holes on the block. I tried swapping the two bolts for one another but that didn't help. When I put the belt on and put it under tension, it seemed to lock it in. Still, this does not seem correct. Has anyone else had this problem? Are there some washers behind the tensioner that I didn't know about and dropped? Edited June 30, 2015 by ColoradoExile Link to comment Share on other sites More sharing options...
Rooster2 Posted June 30, 2015 Share Posted June 30, 2015 I have a 99 Leggie Outback wagon. Recently replaced the A/C belt you described. I have never had any trouble tightening the tensioner. It is a 2 bolt arrangement. Long vertical bolt to create proper belt tightening, the second bolt on the tensioner to "lock in " the tension. No washers used. Send a photo of what yours looks like, if you have not already figured it out. Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 30, 2015 Share Posted June 30, 2015 The two bolts that secure the tensioner to the bracket would not thread in all the way? They should have a 12mm head and be about an inch in length. M8x1.5 thread IIRC. Link to comment Share on other sites More sharing options...
ColoradoExile Posted June 30, 2015 Author Share Posted June 30, 2015 Correct, Fairfax. The two bolts that secure the tensioner to the bracket would not thread in all the way. They do have 12 mm heads and I am certain that they were the ones that were in there originally. Thank you Rooster for your reply. The bolt and nut you refer to worked fine. It's the two bolts that secure the whole tensioner assembly to the block that don't screw in all the way. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted June 30, 2015 Share Posted June 30, 2015 stick a wire/toothpick/w'ever in the hole, mark the depth, pull it out and compare to the bolt's length? Link to comment Share on other sites More sharing options...
johnceggleston Posted June 30, 2015 Share Posted June 30, 2015 are they cross threaded? if no just get some washers. if yes, oops? Link to comment Share on other sites More sharing options...
ColoradoExile Posted July 2, 2015 Author Share Posted July 2, 2015 Thanks to all. Purchased a couple of washers and everything seems to line up fine now. Link to comment Share on other sites More sharing options...
