I type this just in case someone finds this thread on Google. The water pump issue is not something to worry about. If you look at the Ford Tech youtube page he was working on a 10 year old Ford Edge with 180000 miles. What we dont know about that Edge is was the coolant ever changed? I bet Ford techs customera dont think too much about preventative maintenance.
My experience in the Livery industry is these pumps go out somewhere north of 150000 miles. Some guys still have their original pumps after 400k miles. All of the Livery guys just do oil changes and thats it. No special maintenance of any kind.
Thus it is a durable pump and if you want to put 300,000 miles pretty much I would expect 1 water pump change. Thats pretty good when considering nothing else...beaides the cat converter wearing out...will go wrong with the 3.7 liter Duratec.
As for the police department there are articles out there how they do maintenance and what they do is a minimal amount. Many departments get rid of their cars around 80000 miles. They try not to spend time and $$$ where they dont need to.
I highly doubt many people here operate fleet vehicles where you put 70000 miles on an engine and this waterpump issue for the 3.7 liter should not be on the mind.
More paranoid types like myself who believe when the warranty runs out is when things go wrong might want to pre emptively change the pump after the 150k extended warranty expires. However that water pump change isnt neccasary but more so to calm the mind of the paranoid fleet operator who doesnt want to get stuck much like the guy who gets 4wd to operate in NYC. Do we need it...probably not...but in the back of your mind you believe there is that small chance you get stuck.
