First find the drain plug of coolant, unscrew and drain the old coolant, tighten the drain plug, and then pour in new coolant.
Coolant is a kind of antifreeze containing special additives, which is generally used in the cooling system of liquid-cooled engines. Coolant has excellent properties such as anti-freezing in winter, anti-boiling in summer, anti-pollution and anti-corrosion all year round.
Precautions when using coolant:
1. Try to use the same brand of coolant. Different brands of coolants use different metal corrosion inhibitors, so different brands of coolants cannot be mixed.
2. The validity period of coolant is mostly two years (individual products will be longer), and the products should be guaranteed to be within the validity period when adding; When replacing, the old liquid is discharged, and after cleaning the cooling system, the new liquid is replaced;
3. Prevent the use of water. The traditional inorganic coolant can't be mixed with water, which will produce precipitation and seriously affect the normal function of the coolant. Organic coolant can be mixed with water, but water can't be mixed too much.
4. For vehicles using coolant, do not directly supplement tap water. Distilled water or deionized water should be added. If there are no conditions, it is better to add cold boiled water than tap water. If the coolant is lost due to leakage, the same brand of coolant should be replenished. Coolant should be used all year round. It is not scientific to use tap water in summer, and it is not worth the loss.
5. After some cooling fluids are stored for 1 year, there will be a small amount of flocculent precipitation, which is mostly caused by additive precipitation, so it is not necessary to throw it away. If a large number of particles are deposited, it means that the coolant has deteriorated and can no longer be used.
