1988 vert

Belt tensioner bolt is about 3/8" below front crossmember. Undo the bolt and it hits crossmember while it is still screwed into AC mount. As a result, you can't get tensioner out. Shouldn't the tensioner bolt slide out and the tensioner come off?

Motor mount problem?

Thanks

motor mount 'squish' is a common problem, esp in 'southern zones' that experience warmer ambient...try a floor jack under the engine (must use a wide wooden block to prevent oil pan damage...adding 'shims' between the mount and the engine block is a 'low buck' fix for sagging mounts, can use the 'plates' commonly found on pickup truck engine mounts or simply slip 1/2'' nuts (three per mount) on the bolts (need longer bolts, obviously) for 'shims'

Maybe - but most hit it and you'll never get just the bolt out without taking the Tensioner with it. The key is to move the Tensioner back with the Bolt and then tilt both out together. It's a tight fit, but most come out that way. Installation is the reverse - insert the bolt into the Tensioner and then wriggle the Tensioner and bolt as one piece into place.

Thanks everyone

I just came back from my garage and

I bought and installed a shorter bolt. The one that I think was in there stuck out past the back of theAC/tensioner bracket by almost an inch when tensioner was installed. That made the bolt too long, so I bought a bolt that comes amost flush with the back of the bracket and now it goes in and out like a greased pig.

Thanks again
