Thanks to all the topics on water pumps I knew that my 4.4 water pump would fail at around 60K miles. Sure enough, at 65K I started to notice the smallest puddles of coolant in my garage. I had the water pump replaced under CPO along with the belts and coolant flush. Had I not been forewarned, this could have caused problems or damage.

The big question is; is the replacement water pump "improved", or do I need to start looking again at 120K miles?
