youre gonna need to take the clutch cover off to access the water pump internals. also youll need to replace the mechanical seal under the impellar. im positive thats what is causing your leak. not expensive you just have to take the whole impellar out and knock the mechanical seal out of the hole and put the new one in. use a socket the size of the seal to knock the new seal in and re-install. good as new!

i agree, the mechanical seal and another o-ring is what i was going to order from oem picture, not that $. but are talking about taking the entire side of the engine off, all 12 bolts? do i need to drain all the oil and is their a big gasket or o-ring i need to get. sorry, still learning. explain 1 more time on how to get the mechanical seal and impeller apart? again thanks

i would say getting the old seal out of the housing that its in is the hardest part. one little trick is to bend the lip up all the way around the seal ,then it should just pop right out .

then use the right size socket to tap the new one in http://i44.photobucket.com/albums/f9/cataway/3-28-2007LS232.jpg

yes all 12 just be careful pulling the cover off so you dont tear the gasket as they are reusable. youll see it when you pull the clutch cover off what we are talking about. also head over to z400central and search for mechanical seal replacement. has a lot of pics like cataway showed you.
