Need some pro advise....

My guess would be that you put on too much anti sieze. It's not meant to be layered on thick. Or as stated, maybe a issue with the torque wrench.

Unfortunately the water pumps on a isx are solely reliant on a belt so when your belt snaps, you need to stop the truck right away, isx engine's do not handle being overheated well at all. Some engine's can be limped, these are not one of them.
