I have to replace the water pump on my jetta as the bearing has went bad in it causing significant play and destroying the serpetine belt. I don't have the Bentley repair manual but have done some research online only to find that there are two ways of doing this that involve either a 50+ step process from a well established vw enthusiast web site that will take 4 - 8 hours to do or a considerably less step that takes around 40 - 60 minutes to do. The first requires that allot of the engine bay items be removed or relocated and the engine and transmission be unbolted and lifted then shifted to the drives side while the second one requires the dog bone support be unbolted and the engine dropped down to allow for the removal of the water pump. Which of these is right because I'd hate to spend a hole day doing the first and I'd hate to do the second only to break something.
Also is it required to use the G12 coolant or can I use the Prestone extended life coolant?
