Abstract
A cylinder liner for an internal combustion engine is externally threaded at a first end portion. An annular groove having a threaded first side surface is disposed in a cylinder head. The cylinder liner is screwthreadably engaged with threaded annular groove, forcibly engaged with an end surface of the annular groove, and sealed by side thread loading. A seal member and ring disposed about the cylinder liner and in a coolant passage isolates the threads from coolant fluid and optimizes cylinder liner cooling. A minimum crevice volume is provided between the annular groove and the cylinder liner.
