thanks for the info Mustang , there are 4 bolts that do hold the pump to the housing. I needed the advice about removing the pully from the pump, I wasnt sure if it had to be pressed of or bolts held it on. Im glad i can just removeit but taking out the bolts. I have a diagram of the belt routng on the hood for routing the serpentine belt.
I appreciate your advise, it'll be a big help. All the Haynes manual says is to take the pully off , but doesnt say how
