Cooling
The engine has a liquid cooling system.
The water pump is a maintenance-free impeller pump and is driven by V-belts from the
crankshaft pulley.
Depending on the agreed extent of delivery and the design of the engine, the coolant cir-
cuit can be equipped with temperature and level monitors which, in the event of over-
heating, will trigger an advance warning system or, in the event of loss of coolant, shut
the engine down.
Air cleaner
An air cleaner is installed on the engine to filter the air for combustion.
The intervals at which the cleaner should be serviced depend on the specific operating
conditions. Clogged air filters may cause black smoke and reduce power.
The connecting elements between the air cleaner and the inlet manifold should be
checked from time to time for fightness. The ingress of unfiltered air is liable to cause an
increased rate of cylinder and piston wear.
