Engine Coolant
The cooling used in cooling system is mixture of 50%
distilled water and 50% ethylene glycol antifreeze. This
50:50 mixture provides the optimized corrosion
resistaance and fine heat protection.The coolant will
protect the cooling system from freezing at tempera-
ture above -30degrees
(C)
,the mixing ratio of coolant
should be increased to 55% or 60% according to the
figure on the right.
Note:
z
Use high quality ethylene glycol base antifreeze and
mixed with distilled water.Never mix alcohol base an-
tifreeze and different brands of antifreeze
z
l
Theratio of antifreeze should not be more than 60%
or less than 50%
z
l
Do not use anti-leak additive
Warning!
z
DO NOT open radiator cap when the engine is still
hot.Or you may be injured by scalding fluid or steam;
z
Coolant is harmful.DO NOT swallow or stain your
skin or eyes with coolant.In case of accidental swal-
low or stain,flush with plenty of water and consult the
doctor immediately;
z
Keep coolant away from reach of children
Inspection of Cooling Circuit
z
Remove radiator cap1and connect tester2 filler
Warning!
DOT NOT open the radiator when the engine is still
hot
z
Give a pressure of 105kPa and check if the cooling
system can hold this pressure for 10 seconds.
z
If the pressure drops during 10 seconds,it indicates
that there is leaakage with the cooling system.In this
case,check the complete system and replace the leak-
ing parts or components.
Warning!
z
When removing the radiator cap tester,put a rag on
the filler to prevent splash of coolant
z
DO NOT allow a pressure to exceed the radiator
cap release pressure
