The Duramax Cylinder Head Gaskets are starting to show some signs of failure as the engines age and put on some mileage. Signs of a failing head gasket are coolant loss with no sign of leakage, coolant leakage from the overflow bottle or coolant leakage from the engine to cylinder head mating surface.
