Upper Radiator Hose Pressure??

Find someone, maybe a rad shop who can run a chemical test for head gasket. This is a chemical that tests for combustion gases, otherwise known as a block (blok) test

Thanks for the info and Link, Live out in the middle of nowhere so nearest Rad should would be 70 miles away, I don't trust it to make it that far. Might have to get this Kit and do it myself if the smaller fixes don't work.
