If there is a set of bolts holding it onto the other pulleys they are missing or broke. I am guessing it is the key holding it on the shaft. I am wondering if the extra strain of the ac actually running is causing it to move where as when it is off the pulley just moves tight to the others from the inertia and stays there. The easiest thing to do is pull the rad back out and take the pulleys off and see what is happening. I just thought I would get some information first since I won't have time until Friday at the earliest between work and therapy for my leg. The other weird thing. Sometimes when I have it on fresh air vs. cabin air and the ac is running I get whiteish smoke coming out of the vents but it doesn't smell at all. I was thinking maybe with the humidity and temps so high here in NC it was just vapor but now I am not so sure.

Good timing with this thread, same problem here on a 97 t4r 3.4
ac belt has a pulley with a tensioner pulley that the bearing can fail, as mine has, old as it is, the pulley froze to the bolts shaft it rides on, hence the squeel of the belt riding across the frozen pulley, the adjustment bolt/tensioning bolt snapped trying to get it off as well, so I began to search on here and found the following link though not your exact engine/parts, it is insight into the issue.

Question: A/C Belt Tensioner with sparks
Please post how yours turns out, so far, I am having to order the entire assmbly to be safe at around 45.00+
