Probably a smart move to dump it. Its only been a few months since i replaced my PTU (which has been running fine) but the other day when my wife was driving the water pump failed suddenly and pumped all the coolant into the oil pan. Needless to say this one is not going to be a cheap fix. Im going to do the min to get it fired back up and trade it in.
I would reccomend that anyone who plans to run up the miles on their edge either replace their pump($$$$) or check their fluids weekly, although i had just checked everything 2 weeks before the incident so its likely that it just let loose within a day or 2. Ford myst have had the intern design the pump location. Id love to see the FMEA for that component.
Its too bad, we were planning on getting a new edge in a couple years since its a great vehicle in terms of power,cargo, and looks, but this was one failure too many. It was also the first car that ive owned which hasnt made it over 200,000 miles.
