OHNO60 Posted February 10, 2009 Share Posted February 10, 2009 Just a weird question, did any of you guys ever run into a "wet" egr cooler that passed the off truck pressure test but failed on the truck pressurizing the coolant? Had one this week and seemed very odd. Cooler passed vac step of TSB, passed in water tank, but when pressurizing cooling system leaked on the exhaust side like a sieve.

BrunoWilimek Posted February 11, 2009 Share Posted February 11, 2009 You have to get some of them pretty hot to leak. I had one that leaked when hot on the bench, but I left the pressure test adapters on it for the weekend to be able to show the warranty inspector the bubbles, but it held pressure all weekend and would not leak when the inspector was there.
