6.4.3 Coolan
t
Function o
f
Coolant
The coolant possesses cooling, anti-freezing,
and anti-corrosion functions.
Specification of Coolant
When delivery, the cooling system of this
vehicle has been added with coolant, which has an
anti-freezing ability of -35℃. The coolant can be
used throughout the year except for extreme cold
weather, prevent the alloy components of cooling
system from corrosion and the system from scaling
and increase the boiling point of the coolant.
If the anti-freezing ability of coolant needs to
be enhanced during severe cold seasons, the
proportion of coolant additive can be increased
appropriately, but the coolant concentration must
not exceed 65%. Otherwise the antifreezing ability
of coolant may decrease, thus weakening the
cooling effect.
Hint
Specification of coolant: DF-6, -35℃ coolant.
Engine coolant temperature gaug
e
Under normal
driving conditions, the scale
lighting on the temperature gauge ② of engine
coolant on the instrument cluster shall be
approximately at the middle position. When the
engine runs at heavy load and the ambient
temperature is high, the coolant temperature may
rise and the scale reading may increase.
High engine coolant temperature indicator light
When the temperature of the coolant is too
high, the engine temperature indicator light
(red)
in the instrument cluster will be on and the
instrument cluster will display corresponding
graphic & text information to prompt or warn the
driver. At this moment, stop the vehicle and shut
the engine down. Then check the level of the
coolant after the engine cools down.
If the coolant level is normal, the system
overheating may be caused by the failure of
radiation fan. Inspect whether the fuse of radiation
fan fuses, and replace the fuse as the case may be.
=> Refer to Page 402
If the indicator light is on again when you have
driven for a short distance after the fuse is replaced,
immediately stop your vehicle, turn off the engine,
and contact GAC MOTOR dealer for maintenance
as soon as possible.
