So my Expedition has a leaky radiator. Luckily it doesn't over heat, but I can definitely smell the rad fluid. I have already ordered a Lightning radiator to upgrade to, and Im planning to put a Navigator water pump in it as well. Does anyone have a part number for the water pump or are all the Navigator pumps the same from 98-06? I know in 99 the Navi got the DOHC engine, so Im kind of assuming I want a water pump for a 99+ however if I had the part number I could just get one from Ford new… Im also planning to install a Lincoln Mark VIII fan for some added cooling power.
