This has probably been beaten to death previously, but I can't seem to readily find an answer, so my apologies...

My 1972 with 454 (LS5), power steering (N40) and AC (C60) should have come with the A.I.R. system (K19), correct?

I don't have my A.I.R. system (disappeared long before I got the car), but I am adding the idler pulley because getting the belt off between the crankshaft and the water pump was a complete PITA.

I can't seem to find a belt routing diagram anywhere in the AIM for this configuration of LS5, N40, C60 and K19. Really for my own curiosity, does anyone know what this would have looked like?

Thanks in advance.

It's the same as 1973 LS-4 with the same options.

Joe's '73 diagram is correct for a '72 454 with A/C (of course). My '72 AIM does not show it correctly as it does not show AIR with A/C.

Regarding the water pump belt- with or without an idler, it's a tight fit that often doesn't slip over the pulley to remove/replace. I remove the water pump pulley, slip on the belt, then install the pulley.
