So I’m preparing to do the electric fan swap on my 00 V8. I’ve read in a few guides that you need the K061000 serpentine belt and you need to switch the unflanged pulley with a grooved one that fits the belt. I’ve looked at the diagram of the belt set up. Can anyone help me understand... 1. If the hydraulic system is going to be completely removed, why are we replacing the #2 pulley (unflanged) and not the #1 pulley (Hydraulic System) 2. What’s the purpose of changing the serpentine belt during the swap process? Ive never done this swap and any information to help me understand is greatly appreciated.
