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   

- 28 –

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.
