Klinovoj belt of the water pump

At the six-cylinder engine the drive of the water pump is provided with a gear belt – here all should be as it should be.

Business in another way is at the four-cylinder engine: this engine never should be got without клинового a belt and, hence, without a drive of the water pump! Otherwise you risk to receive heavy damage of the engine.

Cold water is heavier hot. It and without the water pump slowly circulates through the engine and a radiator. This thermosiphon and independently circulating cooling is not enough for modern engines. More detailed information is placed in section the Generator.
