I was pushing it hard for a good hour with the speedometer needle buried... On a hot day. Then I got where I was going and the water pump failed as I was parking.
None of my other vehicles has ever needed a water pump... One Dodge, a few Fords, and a bunch of GMs.
So those specific Ford water pumps on the 3.5/3.7 are just trash.
They have a external leak path! Though the coolant has a tendency to evaporate before hitting the ground. I've diagnosed a couple transverse 3.5L's with leaking chain driven water pumps with NO contamination of the oil. Customer complaint were losing coolant.
