Howdy folks!
Do you know which serpentine belt is used on the 1165A1 with 6.5L turbo and 400A generator? I've dug through every TM I can find and can't find a definitive answer for trucks with a serial number over 300,000 (mine is 313,7xx). I found an older TM that specifies a belt for trucks after 196k-ish, but then they changed to the geared fan drive for trucks after 300k. I suspect it might be a different belt, but don't know. The routing is definitely different, with the REV B trucks having an additional idler pulley (Idler pulley #1 in the right diagram of the attached pic.
