Before adding antifreeze, remove the scale of the cooling system and drain the residual water to avoid dilution of the antifreeze and reduce the freezing point of the antifreeze. Antifreeze can only be added to 93% to 95% of the cooling system capacity. The antifreeze is hygroscopic and the cooling system should be sealed. Ethylene glycol and ethanol antifreeze are toxic. Do not touch the skin. Do not use mouth to avoid poisoning. Ethylene glycol is an organic solvent. When filling, do not leak or spill on the body and surface paint to prevent the paint from falling off. When the anti-freeze solution of ethylene glycol or glycerin is reduced due to volatilization, add clean water in case of emergency. Ethanol, glycerol-ethanol antifreeze, the alcohol contained is volatile and burning. Therefore, attention should be paid to fire prevention. Antifreezes of various types, different types and different freezing points cannot be mixed and mixed. (Xu Chengwen)
