Radiator Assembly For Shantui SD22 Bulldozer

Radiator mainly consists of upper box (1), radiator (12), lower box (10) and related attachments.The cooling water flows through thermostat to enter upper box (1), removes air from water, and then flows through the radiator core (12) to enter lower box (10). When the cooling water flows through the radiator core (12), due to the role of the fan in the back end of the radiator, the water in the core is cooled. The cooled cooling water is pumped out from lower box by water pump to the engine’s cylinders.

This radiation system is a closed system. The pressure valve installed on the water tank maintains water tank pressure within a range 0.075 MPa lower than the gauge pressure, so as to increase the evaporation temperature of the cooling water, to reduce water loss, and to increase cooling efficiency. The fan’s (13) power is transmitted by the V-shaped belt wheel on the front of the engine. The forced air from the fan can enhance the cooling effect.
The SD22D bulldozer’s fan pulley (6) is designed to have two specifications. Small pulley is used in summer, and big pulley is used instead in winter when the engine is too cold.
