How hot did you let it get this last time when you said the radiator was cold?

like 220-250, hose's & radiator should have been hot at that temp I would think? like I said water was boiling by by the intake, will have to look into it more tomorrow.. there is no water in my oil or oil in my water.. I have ran 195s in all my mopar's an yes I made sure it was not up side down the coil spring is still in the hose..



Either the pump is not working or the radiator is plugged, I know you said you flushed it but there is a blockage somewhere.

Have you tried it without a thermostat? I always drill two or three 1/8" holes in my thermostats to help let the air out on the initial start up after changing one out or having to drain the system for any reason.
