I am replacing my water pump on this guy and have seemed to run into a problem I got it down to only one bolt that's hiding behind the power steering pump I have scattered my brain trying to see how I could get it the bolt will come out bout won't clear the pulley on power steering pump I don't have puller so I was going to remove the hole pump but can't figure out how? The water pump is the project the power steering pump is holding me up somebody give me a hand thanks.
