The main function of the coolant will be generated during operation of the engine heatdissipated promptly, therefore, good thermal conductivity is a basic requirement for cooling liquid. Hendin automobile hub unit said the replacement cycle is generally a cooling liquid in about 4 years, but in the use of the process should regularly check the coolant, should be checked when the engine is under normal temperature, which not only accurate, but also safe.
In about 4 years to replace:
There are many types of cooling liquid, is currently using more glycol cooling fluid, composed ofethylene glycol and water according to different proportions.
The replacement cycle is generally a cooling liquid in about 4 years, but in the use of the process should regularly check the coolant, should be checked when the engine is under normal temperature, which not only accurate, but also safe.
When the liquid level is lower than the lower limit (MIN), should identify the reasons for the decline of liquid level. Hendin automobile hub unit said that if due to leakage caused by the liquid level decreases, should be added the same brand of coolant, if the liquid level reduced normalcaused by evaporation should add distilled water or deionized water, do not add water, water and other water. If it is found that suspended solids, coolant sediment or smelly, the coolant has changed, should be timely cleaning the cooling system, and replace the coolant.
Do not mix different cooling liquid:
Hendin automobile hub unit said that because of adding cooling liquid of different brands indifferent types of preservatives, anti rust agent, defoaming agent and pigment chemical composition is different, mix easily react, causing precipitation, fouling and corrosion damage,thus affecting the service life of the engine. If you need to change the coolant with other models,it must be the original antifreeze thoroughly drained, and thorough cleaning of the cooling system.
In addition, if the coolant freezing areas using the minimum ambient temperature high than the car, then the coolant may be frozen, freeze will volume expansion, resulting in expansion pipecooling system crack.
