Belts

OK all, I'm looking at the GM service manual from the sticky thread trying to figure out belt numbers. I have the belt part number page in hand, but the lash up diagram is completely different than mine. I have a serpentine belt for the alternator and water pump, and V belts for the power steering and AC. Anyone else have the same configuration and can provide me with the AC belt number? Thanks!

So, the belts I bought are incorrect, and being the hard head that I am, now get to replace the power steering pump, again. I'll keep you posted with parts numbers when I get them figured out. Seems the power steering belt should be 41.5" long and the AC 61" plus. The serpentine is pretty straightforward. Stay tuned, more details next week....

Also, along this line, I've noticed some squeaking in my front end over the last 6 months mostly when the front suspension flexes. Tonight when removing the PS pump I noticed that 3 of the 4 bolts that hold the sway bar to the frame were missing (accounting for the squeak). It's an unusual thing to check, but look at them next time your under the front end to be safe.....

This, along with the Motorhome chassis guide is a good resource for belts. Some of the Motorhome belts were slightly different to the P30 belts, so care should be taken to ensure they sit correctly in the pulleys.

Also use the unit repair manual and exploded parts diagrams. I've found you can sometimes identify replacement GM belts. I'm close inspection, these look to be an exact match whereas other belts can have small tolerances. I'm not sure of the extent to which this matters
