Upper Radiator Hose Pressure??

THANK YOU TO EVERYONE THAT HELPED.

Culprit was the Radiator Cap. Got one today, 16 psi is all they had, they don't even show a 7psi one listed. Put it on today after getting home from picking up the 86 Diplomat, put it on, Warmed it up while I disconnected the Tow Dolly, then drove it 10 miles and No pressure in that hose built up. Still going to replace the upper and lower hoses though, they feel kind of soft when the pressure isn't built up in there LOL.

THANKS AGAIN FELLA's
