Changed all 3 belts this morning and it seems to me that the p/s pump doesn't have any kind of adjustment - the belt has got to be the exact length and that's that. I loosened the 3 nuts that hold the steel p/s pump bracket to the aluminum a/c compressor bracket, and there doesn't seem to be any slotted holes to allow a bit of movement to set the exact belt tension. What's the go here? 304 motor BTW.
