[QUOTE="Fouledplugs, post: 426582, member: 18666"] The most efficient way to diagnose the leak is with a pressure tester. It looks similar to a small hand pump for a bicycle or a football. It screws onto the radiator and allows you to pressurize the cooling system. Naturally, the leak, “should,” show it’s-self and make it easy to pinpoint the problem. Some auto parts store will rent them to you. Good luck. [/QUOTE]
