Does Chuanqi gs4 need to drain water when replacing the water tank?

Pacific Auto Network Chuanqi gs4 must drain when replacing the water tank. The gs4 coolant drain valve is located at the bottom of the radiator. Open the drain cock at the bottom of the radiator to drain the coolant. The performance of engine cooling system is ultimately reflected in the role of refrigerant. In use, we should pay attention to the use of refrigerant. If the consumption of refrigerant decreases, we should pay attention to replacing it.

Refrigerant is the "guardian" of the normal operation of automobile engine, and the performance of engine cooling system is ultimately reflected in the effect of refrigerant. In use, attention should be paid to the use of refrigerant, and if the consumption of refrigerant decreases, attention should be paid to replacement.

Precautions for using frozen liquid:

(1) The volume fraction of the frozen liquid is 40%-60%;

(2) The released frozen liquid shall not be reused, and the discarded frozen liquid shall be treated in strict accordance with relevant laws and regulations;

(3) When replacing the cylinder head, cylinder gasket and radiator, the refrigerant must be replaced;

(4) When the engine is hot, the cooling system is still in a high temperature and high pressure state. Therefore, do not open the radiator cover at this time to prevent burns;

(5) If a large amount of refrigerant is found to be lost, refrigerant can only be added when the engine is cold, so as not to damage the engine;

(6) Frozen liquid and its additives are toxic substances, so please do not touch them and keep them properly;

(7) In case of emergency, if pure water is filled up, the freezing liquid additive should be added in the low temperature area as soon as possible to restore the mixing ratio of the freezing liquid to the normal state and prevent the parts from freezing.

In addition, the freezing liquid may have different concentrations, and a freezing liquid containing water may be used. However, if the concentration is not appropriate, solidification may occur. Therefore, it is necessary to use long-acting frozen liquid with appropriate concentration for different areas.
