CORRUPTED EPC BELTS
I am no EPC wizard to help you sort out your parts list... beware it is loaded with inconsistencies even on-line.
The top issue being the EPC SERPENTINE BELT references must be cross checked.
DO read your own physical belt exact reference.
It's not easy to find belt in the right spot for reading. Having the right parts on-hand will save your time later.
