Cooler water comes from the radiator which flows through the canals in the engine come to the engine block. Cylinder cover is placed on top of it and crankcase is located below it. Leak proofing tests of water and oil canals in the engine block is made in the production line of HEMA. Also we are able to the Plato honing method.
