I"m new to the forum, but do have some input regarding the water pump. I just sold my 2010 SHO (PP) with 230,000 miles on her, and running strong. I bought her at 91,000miles. I always was concerned about the water pump,Im not sure if the original owner replaced it at some point? , but I put 139.000 miles on the water pump that was on the car when I bought it. The key to water pump longevity is to routinely perform coolant flushes every 30,000 miles with distilled water and replace with Ford recommended coolant to help prevent electrolysis.Replacing the water pump is a $3000 job, being Ford configured it in the engine unlike the ecoboost in the F 150 which is external.My opinion is, if its not leaking, dont replace it.Whose to say the new pump doesnt blow out soon after install?Keep your eye on the coolant reservoir weekly and keep the $3000 grand in the bank.Pop the hood look to see if the coolant is up to the mark and keep trucking.My wife has a 14' CX9, same design. Lots of city driving.Hers went out at 100.000.Pump bearing started making noise.$3000 later fixed.Flushing the coolant is cheaper preventative maintenance then dumping $3000 on a water pump thats not leaking.
