This month we have have 4 water pumps to come back in our shop all where on 6.0 's powerstrokes. 2 which had major damage ,the bearing in the waterpump was backing out of the houseing causing the fan to come forward about 1/2 inch ,in turn it got into the wiring harness for the viscous fan shorting out the PCM and causing major damage to to the wiring harness, fan blades. The PCM ground that was shorted caused the truck to also have a no crank conditiion. I had no ground at the starter relay to energize the starter relay! After repairing all of that mess replaced the PCM and my custumers truck cranked right after was reprogramming completed!! Now Im in no way bashing NAPA Im just trying to let everyone that they may have a bad run of water pumps !!
