My 7.3 randomly overheated the other day. Has been fine leading up to this. I thought maybe the thermostat was stuck so I pulled that. While I had it off filled the water pump up with water at the thermostat housing opening, I then bumped the engine over and there was not water coming out, I then started the engine and it would just weakly flowing water out of the thermostat housing. I assumed if the pump was working correctly it would just gush out of there? Do I have a bad water pump? Water pump was replaced about 10K miles ago with a napa unit. Thinking maybe the impeller came loose. What do you guys think?
