I have a 99 ram 5.9l and when I start it I get a funny sound like marbles in the dashboard. I have checked the condenser for clogage but its fine. Any help would be apperciated

 

Does it sound more like water or marbles. If it sounds like water I heared that it might be air in you radiator 1. Check and fill radiator and also check the radiator cap to make sure there is no crack on the gasket. Or for any crack on the head it self.
