Reiz, change several barrels of antifreeze.

Generally speaking, about 4-6 liters, it is enough to change antifreeze once every 3-4 years. The liquid level is normal as long as it is between MAX-MIN lines: 1. Before replacing antifreeze, the old antifreeze should be discharged first, and then a new antifreeze should be replaced.

2. Before replacing antifreeze, open the drain valve of the water tank. Usually this position is under the car. Different types of cars are placed in different locations. After the antifreeze is released, continue cleaning the cooling system.

3. Clean water can be used for cleaning, and it can be continuously injected into the engine cooling system. It should be noted that in the process of cleaning, the engine should be idling to keep the clean water circulating inside until the engine cooling system releases clean water.

4, wait for a period of time, after all the clear water flows out, then close the water valve, at this time, you can add new antifreeze and fill it to the position where the liquid level is between max and min water level scales, so as to ensure the normal operation of the engine.
