Arrizo 5 used the long-life refrigerant of the Great Wall, and 8 liters need to be replaced. It is best to use original coolant, so there is no need to clean the cooling system. If the freezing point of the coolant is insufficient, it can be replaced with a coolant with a lower freezing point or cooling oil. However, the cooling system, including water tank, engine water jacket and coolant pipe, must be thoroughly cleaned with clean water. Different kinds of coolant shall not be mixed. Even coolants of the same color may have very different compositions. The mixing of different kinds of coolant may lead to chemical changes in its composition, blocking or corroding the cooling system pipeline and engine water jacket. If the sudden lack of cooling water leads to "boiling" during driving, stop the engine as soon as possible, keep the engine idling and turn the engine hood and air conditioning warm air to the maximum to help the engine dissipate heat and cool down. Don't put out the engine until the engine water temperature drops. After the engine is cooled, tap water can be added for emergency use.
