2.2.18. Intercooler
The intercooler is air to air type and has a large cooling fan capacity. The intercooler life and
performance depends on the intake air condition greatly. Fouled air pollutes and clogs the air fins of
intercooler. As a result of this, the engine output is decreased and engine malfunction is occurred. So
you always check whether the intake air systems like air filter element are worn or polluted.
–
Cleaning of intercooler fins : Every 600 hours.
2.2.19. Cooling system
The engine has a liquid-cooling system.
The water pump is a maintenance-free impeller pump driven by V-belts from the crankshaft pulley.
Depending on the agreed extent of delivery and the design of the engine, the coolant circuit can be
equipped with temperature monitors which, in the event of loss of coolant, shut the engine down.
