How often do those water pumps fail?My list includes Fords with internal water pumps. Those being 3.5, 3.5 Ecoboost and the 3.7. Second is Fords 2.7 which has a oil submerged rubber cogged belt which drives the oil pump.
As for the list are we talking NEW? "out there now" - most are decent. But I suspect any and all Hyundai/KIA engine. Sorry.
