hot rod ...this is the neatest thing i ever seen for radiators ...it is called a spill-less funnel the thing comes with abought every adapter you can imagine ...an you attach it to your fill hole like a radiator cap ...ya then just keep it full of coolant while the vehicle is runnin an it takes out all the air ...an when ya done there is a long plug ya stick down it to close it off an remove it ...dont make a mess an it removes ALL THE AIR !
