Yes, my H2O pump failed last May. Car was well out of warranty, plus I noticed the temp. gauge above it's normal position before any damage was done. Always, always replace the tensioner when doing the pump. Mine was seized and talking to a no. of Ford mechanics, confirmed this as a very common problem.
To those who've done it more than once-are you getting another OEM Ford pump installed? I installed an aftermarket unit from TRW. It did have a plastic impeller, but white in colour and appeared far more durable than the black Ford piece o' crap!
