Hi, I have a 1998 patriot with a CAT 3126. I see coolant leaking from the back side of the water pump. It looks like the area between the pump and engine block. Has any one had this happen, and could it be any thing but the pump or seal behind the pump? No coolant above the pump, and if the pump is the problem, how hard is it to change the pump out? Note this RV has a rear radiator.
