Timing chain replacement

Hi and thanks for using 2CarPros. Com.

The right side (passenger side) cam chain has to come off first and is installed last. Take a look at picture 1. It shows how the chains are in place. Here are the directions. The directions are for the primary chain, left cam and right cam. Starting with picture 2, all pictures correlate with these directions.
