01 VW jetta glx vr6 2.8l water pump replacement

I generally do all of my own repairs short of tearing apart the transmission which is the only thing that I have never learned how to do so taking it to an hourly mechanic and paying close to $100 hour labor is not going to happen. I’m looking for clarification on information on which method is correct or if both are options not that I should be helpless and let someone else do the work.
