Re: Need larger radiator for 71 C10 with L6

From reading up some aluminum rads can cool better from being able to have larger wider tubes then old 4 core copper rads

Stock caps are 15 psi with overflow tank i would be inclined to look for a cap at 15 psi with overflow capability

Places like rock auto list all aluminium rads for our trucks
