Add antifreeze.
If water circulates through the engine and flows into the cooling box behind the air intake grille, the impure water will produce scale and block the cooling system. This situation will lead to increased engine wear. and high temperature water is easily evaporated, resulting in lack of water in the cooling system, which will lead to cylinder pulling, cylinder head deformation, and more seriously, engine scrapping .
The antifreeze formula is composed of pure water and methanol as well as other substances, including pigments, preservatives, descalers, etc. It is recommended to use antifreeze as engine circulating water to ensure good engine heat dissipation. Effective protection against cold and frost is also a prerequisite for ensuring good engine operating conditions.

Notes:
1. use the same brand of antifreeze. Different brands of antifreeze use different metal corrosion inhibitors, so antifreezes from different brands cannot be mixed.
2. The validity period of antifreeze is a maximum of two years. When adding, you must confirm that the product is within the validity period. When replacing, the old fluid must be drained and the cooling system cooled. must be cleaned before replacing with new fluid.
3. Avoid mixing it with water. Traditional inorganic antifreeze cannot be mixed with water, as this will cause precipitation and seriously affect the normal operation of the antifreeze.
4. For vehicles that use antifreeze, do not fill tap water directly. If there is no condition, it is better to add boiled waterdregs cold rather than adding tap water.
5. After one year of antifreeze storage, a small amount of flocculating precipitation will appear. This phenomenon is mainly caused by the precipitation of additives and does not need to be discarded. If a large amount of particles precipitate, this indicates that the antifreeze has deteriorated and can no longer be used. When replacing, be sure to remove all used antifreeze and clean the water tank thoroughly.
