CHAPTER 16 Cooling System

1 Maintenance guide
Drainage and refilling of cooling system
Proportion of ethylene-glycol is definite,so
as to ensure at least 50% of ethylene-glycol
solution being used for all emission ports
and air holes of engine block ,during the
process of coolant drainage and washing.
Volume of cooling system for 1.1 liter
engine is 4.8 -5.0 liter,listed volume during
the produre of refilling,including extra
amount of atmosphere drained and
remained in cooling system after static
refilling.According to correct filling
proportion and the following procedures,it
will ensure that density of ethylene-glycol is
50% in the cooling system,so as to simplify
the refilling work,see the radiator volumn of
static refilling for reference,at least every 5
years or driving 240000 km , taking the first
arrival for standard, the engine cooling
system should be drained and refilled with
fresh coolant accordingly.
Caution: Make sure that pressure
temperature of cooling system is much
higher than solution boiling point in the
radiator while preventing boiling at the
same time.To avoid the damger of being
burned,do not remove the cap while the
engine and radiator are still hot,because it
will lead the solution boiling and having
explosive force probably,resulting in
solution rejecting to the engine wing and
hurting the user who remove the cap.
Hint: It must be sure that you should use
regulated coolant,if you don’t use regulated
brand of coolant ,time of replacing the
engine coolant should be shortened ,that is
driving 50000 km or 2 years.

Drainage
Hint: It is not right to drain the coolant to
the full,unless when you remove the water
pump.You should pay attention that this
procedure will increase the amount of
coolant for diluting the dangerous waste
materials.
1 Keep vehicle level.
2 Remove reservoir tank cap according to
the following procedures after the engine is
cooled.Turn the cap to hill holder
slowly,anti-clockwise.Don’t give the
pressure cap more pressure while turning.It
will be fizzing while draining the remaining
atmosphere,you should continue to turn the
radiator cap anti-clockwise,until you open
it.
Hint: Retrieve and store the old coolant in
the old reservoir tank at regular
intervals,that procedure greatly increase the


amount of coolant for diluting the
dangerous waste materials.
1 Put the drain tray under vichle to collect
the old coolant.
2 Loosen the outlet hose clamp mounted on
the left side of radiator back,remove outlet
hose of radiator
3 Loosen the hose which coolant tank to
manifold inlet port, remove tank and hose.
It is enough to remove the bottom radiator
pipe and tank hose only if you carry out
drainage partly.
Attention: Make appropriate dispose of old
coolant,don’t put the old coolant into the
sewer.Ethylene-glycol anti-icing agent is a
kind of extreme poisonous chemical agent.It

is illegal to dispose the ethylene –glycol in
the sewer or groundwater for it will destroy
the ecological environment.
4 Refillling 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 collar clamp of radiator vent hose
2 Reinstall after draining the waste water
away,clean the reservoir tank with water.
Attention:
Add ethylene-glycol 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 wheher 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 atomosphere 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 untill 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 anti-icing
function of engine coolant with
refractometer and heat hydrometer to make
sure that it has appropriate anti-icing
ability.19℃-35

O

F protecion.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 referrence.
Cleaning of radiator
Caution:Don’t spray the water to the hot
radiator,hot gas generated will injure you or
otherr 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 prssure
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
compression atmosphere through the
radiator,blow from the back side to
frontwards,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.
