It seems that Cummins is having a supply problem. I am in need of two Aftercoolers for the Cummins QSC8.3-490. Mine are shot and my mechanic can not find a replacement. Any Diesel graveyards out there for parts or contacts for new ones?
May want to post an inquiry on boatdiesel.com. obviously great care must be taken if considering a used aftercooler. Not many mechanics would recommend going that route.
