My roomate says there was a threaded hole on the block on his 2.8 for it....I don't see why yours should be different.

 

Really!!

I've got a service manual to a 1991 Beretta.....................and for the life of me I cannot find the torque spec for the idler.

 

It appears to be a 15 mm headed bolt from the pictures. So. I would use the torque spec for the rear bolts of the compressor...........36 lb-ft.

 

......or you could use the torque spec for the tensioner bolt.

 

Which is 40 lb-ft. Both are the same diameter bolts.

 

Its your call. ;)

Nice... so is there a certain belt PN for this, or do we have to measure it ourselves?

 

i used part NAPA part# 060615 and it fits great (that's for the 3.1 MPFI of course). i asked for a belt for an '88 Corsica with a 2.8 V6 and no AC.

An FYI, the HELP! line makes bypass kits for AC deletion as well, I was looking through a pamphlet today at work and saw them. Just another route people can take I guess.

so the LQ1 does not have this mounting hole?

 

i'll have to check next time i'm at work.
