I threw my serpentine belt yesterday on my 1990 Chevrolet 454 SS pickup, and discovered that the belt diagram has 'disappeared' from the engine compartment. The local Chevy dealer tells me that the belt diagram sticker is no longer available. I need to know the correct routing for this belt!

Good evening!

It is a big block 454, with smog pump, and AC compressor.1990. I recognized one of the pictures, but when I went to this reply page, the pictures aren't present for me to relay to you (I think that it was the third one). A bigger picture would be a big help.

Really appreciate the feedback!
