Polyrib
I found a DIY for changing the Polyrib belt on the 996. The instruction includes rotating the tensioner pulley with a 24mm socket. The socket will not fit by the sheet metal of the engine carrier on the 6GT3. What do you use to release tension on the Polyrib (serpentine) belt?
A little more searing and I found the answer on Renntech:
"I just changed my polyrib belt on my 2004 GT3. Just an FYI, you cannot use a 24mm socket because you do not have the space because of an aluminum bracket holding the motor that runs right in front of the tensioning pulley. A 24mm boxed end wrench is what you need. The spacing between the aluminum bracket and belt tensioner pulley is tight. I had to use a screw driver to lightly pry to open the gap to fit my wrench within the space. Also, the pulley layout is different so draw the layout before removing the belt. When removing or replacing space is very limited and not as open as the picture illustrates entire procedure should take 30-45 minutes. Good Luck.

Duh, obvious now. I need to pick up a 24mm box wrench, the open end will not hold..

I changed my belt last night. I picked up a 24mm box end wrench. Not as easy as I thought. I loosened the top two bolts attaching the motor carrier panel - I don't believe I could have pried and opening wide enough, to slip in the wrench, without backing off those bolts. (I had the bumper and exhaust off the car.) Let me also say that routing the new belt, with the bumper and exhaust installed, must be a bear.
If I was to do this again, I would grind down the end of the wrench until it slipped on.
These are the bolts I loosened:
Here is where I would grind the wrench.
As an observation, the old belt was stretched a couple inches when compared to the new belt.
