Cooling systems generally used in work machines include a fan, a fan cavity and a water pump. The fan draws air from the radiator, usually at the front of the engine, and this air helps reduce the temperature of the coolant as it passes through the radiator. The water pump is used to pump coolant from the radiator into the engine and back again.
Cooling systems used in Komatsu construction machines are based on a similar principle. However, a particular model’s cooling system may vary depending on engine type and other factors. Therefore, the term “Komatsu fan pump” can take on a more specific meaning depending on a specific model or engine type.
