According to the developers, the air coolers are installed in pairs on both sides of the engine, have a symmetrical design and are used to cool the charge air. Each air cooler consists of a welded housing, cooling tubes, covers and seals. Technical water is used as a coolant.

The device works as a heat exchanger: water enters through a pipe in the lower cover, passes through the air cooler tubes and exits through a pipe in the upper cover. Cooled air enters the diesel air receiver through windows.
