So I'm trying to pressure test my cooling system before I put everything back together. The universal kit I have won't seal with any adapter. Does anyone make an adapter that screws into the coolant crossover tube that will hook up to a pressure tester? Also do you know of a good adapter that would screw into the coolant crossover that would accept like a funnel? I have a universal funnel to burp the cooling system but I have to hold it there. I could tape it I guess but just don't like the idea of that.
