Problem changing drive belt
My IS has 100K and I decided to change the drive belt.
However, I tried loosing the tensioner bolt by turning it clockwise (left threaded) but it doesn't seem to be getting more loose. I then proceeded to pull upwards with a torque wrench and it won't budge.
Any ideas what I could be doing wrong.

All you need is a breaker bar, a 21mm or 22mm socket (not sure but somewhere in the low 20's), new drive belt, and a helper. First, just take off the front engine bay cover and the engine cover. Put the socket and breaker bar on the tensioner bolt and pull up to the left to release tension (don't turn bolt unless it is completely tightened and you can't pull tensioner). Now have a helper take off the belt while you're pulling the tensioner. The install is just opposite, pull the tensioner and have another person put the belt in place. I forgot specifically, but I think it was easiest to slip the belt on the tensioner last. Then just release the tensioner and you're done. Tighten the tensioner bolt if necessary. (Here's where I messed up on, other kids in my Auto Tech class "loosened" the bolt by the "lefty loosey" method. I tried turning it right but it seemed to never stop, and the tensioner completely fell apart into the bay. That's when I found out the tensioner bolt is a reverse thread meaning you turn left to tighten and right to loosen.

Might sound like a dumb question but are you sure you're trying to loosen the tensioner? I just went outside and checked right now using a serpentine belt wrench and right when I put the socket onto the bolt and pull upward, the belt comes loose.
