z Never mix different trademarks of engine oils.
z Periodically replace the engine oil as per the maintenance regulations.
III. Coolant
Make sure to use clean automotive antifreeze coolant featuring antifreeze in winter, anti-boiling in summer, and
anti-corrosion, anti-rusting, and anti-scaling.
Take cautions during the operation:
a. Always use coolant throughout the year and pay attention to the use continuity of the coolant.
b. Depending on the temperature of the region in which the vehicle is used, choose the coolant with different freezing
point. The freezing point of the coolant shall be at least 10ºC below the lowest temperature of the region, in order to
maintain the antifreeze function.
c. Purchase the qualified coolant product, in order to prevent damaging the engine and causing unnecessary economic
losses due to use of disqualified product.
d. Never mix different trademarks of coolants nor use such mixed coolant, in order to prevent the chemical reaction
from impairing the respective comprehensive anti-corrosion performance.
e. Never add the hard water such as well water or running water. Upon the detection of suspended material, sediment,
or smelliness phenomenon in the coolant, it indicates that the coolant is deteriorated and becomes ineffective due to
chemical reaction. In such case, timely clean the cooling system and thoroughly replace the coolant.
f. The glycol coolant is one toxic substance and is harmful to the liver. Never swallow the coolant. In event of skin
exposure to the coolant, thoroughly clean with water immediately. In addition, the nitrite anti-corrosion additive in the
coolant is one carcinogenic substance. Do not dispose the used coolant randomly, in order to prevent contaminating
the environment.
Notice!
z Upon the detection of sudden drop in coolant level, check for cause immediately.
z The cooling system is under pressurized state! Never open the cap of the coolant compensation tank or radiator
while the engine is still hot, or it will lead to scalding danger!
