Ok cool. Thanks. I did take a mani plug out and it is filled w antifreeze..i squeeze the upper hose and see bottom hose move and fluid in radiator swash.While waiting for other more qualified people to opine i would recommend "burping the system" . It will help get air out if that's the problem and wont hurt anything so its worth a try. Found this link to get you in the ballpark.
