1 suggestion. The mechanical seal behind the water pump impeller is easily damaged and I would suggest that you just buy a new one. I replaced my flywheel without replacing the mech. seal and as soon as I cranked it the seal went out. I believe you can fix this by just applying a little antifreeze to the seal for lubrication before you put the impeller back on. Otherwise you will be pulling the cover back off to replace the seal anyways. So you can try to lube the seal you have or go ahead with a new one ($12) and I lubed my new one when I put it in too.
