4 Refilling after draining the coolant from
cooling system
Attention: Don’t use cooling system sealant
or similar sealant unless there are some
regulated exceptions, it will prevent coolant
from flowing in the cooling system and
engine parts, coolant block will result in
engine too hot or cooling system and engine
parts assembly being damaged.
1 Tighten clip of radiator vent hose
2 Reinstall after draining the waste water
away, clean the reservoir tank with water.
Attention:
Add ethylene-glycol coolant ratified for use
by Chery Company while refilling, you
should use mixture of 50% ethylene-glycol
and 50% drinking water to fill in the
cooling system ,if it is not necessary to
wash the system, refilling instead.
3 Refill the cooling system slowly through
coolant tank, according to the following
procedures.
3.1 Add mixture of 50% ethylene-glycol
and 50% drinking water until the coolant is
in the position between maximum mark and
minimum mark of the coolant tank.
3.2 Check to see whether or not the coolant
is in the position between maximum mark
and minimum mark of the reservoir tank
once more after two minutes, continue to
add the solution until it achieve the standard
3.3 Start the engine for warming up ,make
the coolant flowing from the radiator so as
to get rid of the air of engine cooling
system ,check to see whether or not the
coolant is in the position between maximum
and minimum mark of the reservoir tank,
continue to add until it is up to the standard.
4 Install reservoir tank cap, make sure that
the arrow on it is showing no difference
with the direction of coolant overflow pipe.
5 Carry out heating and cooling the engine
for three times, then examine the engine
anti-icing function of engine coolant with
refractometer and heat hydrometer to make
sure that it has appropriate anti-icing
ability.19 -35

F protection. Abstract some
mixture of coolant from the reservoir tank
for the use of examination.
Washing
Washing engine cooling system:
Washing procedures
Various of methods and equipments can be
used to wash the cooling system. If you
want to use special equipment such as circle
washing apparatus, please see the
manufacturer’s directions for reference.
Cleaning of radiator
Caution: Don’t spray the water to the hot
radiator, hot gas generated will injure you
or other people.
Attention: Cooling fin is necessary for good
performance of heat conduction, don’t
brush the fin, in case the fin will be
damaged and function of heat conduction is
not good.
Attention: You can clean the radiator fin
with compression atmosphere or water, the
pressure shall not exceed 150kpa,it will
damage the radiator while the pressure
exceeding 150 kpa, clean front side of
radiator once every year. Clean front side of
condenser, blow and wash the small worms
and tree leaves away from it with
compressed air through the radiator, blow
from the back side towards front, you can
use water pipe to pour the water in through
the radiator, you wash with water only
when the engine doesn’t work and being
cooled.
