    • 6bta\'s aftercooler service

      This topic has 9 replies, has 4 voices, and was last updated byPhilip 6 years ago

      March 20, 2018 at 6:35 pm Tony, hello , I bought the aftercooler service bundle from you, removed my aftercooler for my 1999 6bta’s 370hp 200hrs rack kept pursuit 3400 express. Removed end caps ,no coil obstruction found, I like to do the full service like shown in your video, but the sleeves won’t move, I soaked with trizol lube, tried heat no luck. My question is should use a press next, or at all? Since this would have to be done in a vertical orientationĀ
