PLEASE HELP!! I have 2006 Nissan Frontier V6 Im trying to remove the water pump but it seems to be attached to more that what the books says holds it in place. The 2 screws that are supposed to back the water pump out will not and did not do as described in manual. What would hold the water in place and prevent removal. I seem to have broken a piece off the engine? I have never run into issues like this as I have worked on vehicles all my adult life? Does anyone know a trick or if I damaged something internal? Im paassed the point of taking it to a shop as I have half the engine taken apart.
