Cooling System
The function of the cooling system is to cre-
ate an optimum temperature condition for
the engine to operate under any operating
condition.
The cooling system in your vehicle is filled
with ethylene glycol based engine coolant.
The coolant should be replaced every year.
Even when the engine is not running,
the electric cooling fan of the engine
under the engine hood may start and cause
injuries. Therefore, keep hands, clothes and
tools away from the electric fan under the
engine hood.
The heaters, radiator hoses and other
components of the engine may get
very hot. Do not touch these components.
Otherwise, you may be burnt. Do not run
the engine in case of coolant leakage. Oth-
erwise, this may cause all coolant run off.
The engine may catch fire and you may be
burnt. Therefore, all of the leakage points
should be repaired before driving.
Dispose of the used antifreeze fluid
according to relative environment
protection laws.
Check Engine Coolant
The vehicle must be stopped on level
ground when checking the coolant level.
Check that the coolant level in the coolant
reservoir is between F and L lines. If the
coolant in the coolant reservoir is boiling, do
not perform any operation until it has cooled
down. If the coolant level is lower than L
line, fill the coolant reservoir with engine
coolant according to the specified proce-
dures.
How to Fill Coolant Reservoir
with Coolant
JLB-4G13T Engine
Do not open the pressure cap of the coolant
reservoir until the cooling system (including
pressure cap of the reservoir and upper
radiator hose) has cooled down.
1.
Slowly turn the pressure cap counter-
clockwise. If a whooshing sound is
heard, do not open it until the sound dis-
appears. The whooshing sound means
that the pressure in the reservoir is still
present.
2.
Continue turning the pressure cap and
remove it.
The steam and boiling liquid in a hot
cooling system could spray out, and
you may be seriously burnt. Because they
are under pressure, once the pressure cap
of the reservoir is opened, even it is slightly
opened, the boiling liquid could spray out.
Never open the pressure cap when the
cooling system is still hot, including the
pressure cap of the reservoir. If you need to
open the pressure cap, be sure to wait for
the cooling system and the pressure cap of
the reservoir to cool down.
