Will the air in the car water tank be discharged on its own? The simplest way to vent the car water tank If there is air in the car water tank, the effect of the coolant will be greatly reduced, but there is no need to worry, as long as you keep the engine running, the water tank will discharge the air by itself, because the top of the water tank has In the drainage pipe, the gas temperature and water temperature are relatively high. When the cooling water expands, the air will be discharged to the atmosphere through the drainage pipe. If it is artificial exhaust, it is also possible. We will preheat the vehicle for about 8 minutes after starting it. After the cooling fan starts to rotate, the antifreeze level will drop a little. At this time, fill up the antifreeze and close the water tank cap. Okay, this is also the simplest way to vent the car water tank. However, this method cannot completely solve the air problem in the water tank. If you want to completely solve it, you need to replace the antifreeze and completely discharge the air during the process of replacing the coolant. The steps are as follows: 1. Unscrew the water tank cover, open the water tank drain valve, and release the antifreeze. 2. Insert the rubber tube connected to the tap water pipe into the water filling port of the water tank, let tap water continuously flow through the engine cooling system, and let the engine idle for 3-5 minutes until clean water is released from the water tank. 3. Fill up the antifreeze from the water filling port of the water tank. The antifreeze level should not exceed the upper limit, which is the "Max" scale line. 4. Start the engine and run it at idle speed for about 8 minutes. Unscrew the water tank cover. At this time, part of the air will be discharged from the cooling system. The liquid level will drop a little, and then it will be refilled.
