Just to allay any fears that the serpentine setup could possibly have interference issues with the frame
plenty of room to push the 5 rib belt up into place between the pulleys and the frame, even though it appears otherwise in the pics. 5 rib Belt rides in on the 6 rib crank pulley & alt, and outwards on the AC pulley for proper alignment
(+) batt cable from starter to alt is uprated & relocated along inner fender well, instead of over the engine, seems safer to me.
Mine (Serpentine belt, Gates K050523) ended up being tighter than in the test mock ups - the AC compressor could not be positioned less than 1/2 tensioned in it's adjustment range due to interference with the Allison Header O2 bung - this meant the belt is pretty much tensioned with very little push in on the alternator.
The lower timing cover needs shaving to clear the inner lip of the crank pulley in the bottom forward corner, and along the diagonal rise to the rear to clear the serpentine belt.
The down side to this is that there is maybe not enough room between the alt B+ terminal and the R134a line fitting to get the adaptor on if I need to service the AC again.
If I replace the belt down the road, I'll go 5-10mm longer.
