Having the oil cooler crack is something we all dealt with, but I Got an aluminum one from BELKEBIR, which is some Chinese knock off not doorman as I heard they had issues, but has anyone else had issues with theirs when replacing it with aluminum? I saw this on the side of the radiator on the unit and didn't know if this is bad casting or just apart of the molding process. The raised flat edges where the bolt goes in and around it. Anyone have any input.
