Dry cylinder liners are commonly used in smaller engines and passenger vehicles where cooling demands are lower. They do not come into direct contact with the engine’s cooling system, but are pressed or fitted into the engine block, which is used for heat dissipation.
Wet cylinder liners are commonly used in heavy-duty engines where efficient cooling is critical. They are in direct contact with and surrounded by the engine’s coolant, helping efficiently dissipate heat. While wet cylinder liners provide better cooling performance, they are more susceptible to corrosion if the cooling system is not properly checked and maintained.
Prevention is the best practice when it comes to cavitation, and that task falls on the engine coolant.
