1,Unscrew the water tank cover and open the water tank drain valve, usually at the bottom of the car, to release the antifreeze.

2,Clean the cooling system and continuously pour clean water into the engine cooling system. During the flushing process, the engine should be operated at idling speed to keep the internal clean water circulating until the water tank releases clean water.

3.Stop injecting clean water, wait for the clean water to run out, and close the water valve.

4.Add new antifreeze until the liquid level is between the max and min water level scales.

5.Put the lid on, start the car, and let the engine run at idle speed for two or three minutes, the cooling system will exhaust the internal air, and the antifreeze level will decrease. At this time, the antifreeze should be added again.

What are the consequences of adding too much antifreeze

There will be no effect if the regular brand of antifreeze is added too much. The added antifreeze will be thermally expanded during the use of the car and overflow from the pressure relief valve. There is no harm, but some stains will be left. , But it is best to use a syringe to pump out the antifreeze that exceeds the maximum water level.

Antifreeze has a shelf life, which is generally about 2 years, and high-quality long-lasting ones have 5 years. Once the antifreeze fluid exceeds the shelf life, the engine water channel will easily cause rust, which will cause blockage and cause the engine to become hot or even boiling.

☑Notice:On the other hand, the antifreeze produced by some inferior manufacturers is corrosive, which will not only cause damage to the cooling system, but the excessive antifreeze overflow will cause damage to the wires and other equipment in the engine compartment. In severe cases, it will directly ablate the water tank and flow into the engine.
