Any Mopar Tech's here - Grand cherokee 4.7 loosing coolant.

Well I tried a couple things you guys suggested. I took the rad cap off, clamped off the overflow tube. Started it up from cold and watched to see if it started pushing antifreeze out. Before it got 1/4 of the way warmed up it was pushing antifreeze out the top of the radiator.
So then I put the cap back on and waited for it to get up to temp, once it was warmed up, the upper radiator hose was very hard, maybe not rock hard, but much harder to squeeze that when it was cold.
So to me that's two indications that I might have a head gasket problem. Might go a step further and try the head gasket leak detection tool, or pull the plugs and look at them.
