How to empty the Mercedes Benz water tank water A45?

1. Automatic air exhaust with return pipe.

As long as the return pipe is not blocked, the flowing water is unblocked, and there is no need for manual exhaust; There are two water pipes on this kind of car kettle, one is to feed water into the engine, and one is the return pipe to the water tank or cylinder head, it should be noted that after adding enough water, do not screw the kettle lid immediately, start the engine, and wait until the water return pipe is flowing continuously, you can screw it on, if you tighten the kettle cover in advance, the air in the water pipe can not be discharged, and the water in the cavity system is not circulating, and it is easy to high temperature.

2. Do not bring back water pipes.

There is only one water pipe on the kettle, and this kind of car must exhaust the air manually, otherwise how much antifreeze can be turned out; What I want to say here is that the location of the air exhaust must be selected correctly, otherwise the air will not be discharged.

3. Exhaust method of BMW equipped with electronic water pump.

a. After filling up the antifreeze, the water tank cover is open, and then insert the key and turn on the ignition switch (do not start the engine, but turn on the power).

b. The heating mode of air conditioner has the highest temperature modulation and the smallest air volume modulation.

c. The running lights are turned on, that is, the headlight switch is dialed to the right gear.

d. Step on the accelerator to the end, about 10 seconds, and you will hear the sound of the electronic water pump working.

Hello! Audi A4L does not need to exhaust air to add water from the kettle, if there is air, look at the water pipe on the water tank There is a small water pipe, clamp it down and slowly flow the air.

Audi A4 water tank filling method:

Open the hood with the water tank on the right side. When opening the hood, you need to push the hood latch in; Open the lid of the water tank and add water to the appropriate position. Note that the water added must be clean water; Close the water tank lid and close the hood.

Automobile water tank, also known as radiator, is the main part of the automobile cooling system; The function is to dissipate heat, the cooling water absorbs heat in the water jacket, dissipates the heat after flowing to the radiator, and then returns to the water jacket to circulate to achieve temperature regulation. It is an integral part of the engine of the car.

The water tank is an important part of the water-cooled engine, as an important component of the water-cooled engine heat dissipation circuit, it can absorb the heat of the cylinder block and prevent the engine from overheating due to the large specific heat capacity of the water, and the temperature does not rise very much after absorbing the heat of the cylinder block, so the heat of the engine passes through the liquid circuit of cooling water, and the water is used as the heat carrier to conduct heat, and then dissipates heat in a convection mode through a large area of heat sink to maintain the appropriate working temperature of the engine.

There are deflation bolts in the driving room, first open the deflation bolts, add water to the water tank, there are bubbles on the side of the deflation bolts, until the bubbles disappear, the water tank can be filled, and then put the air deflation pipe under the spare jack in front.

Summary. Hello, the engine water tank exhaust air, 1, this is no air exhaust, he started the automatic circulation of air exhaust, you can disassemble the warm air water pipe to exhaust the air, wait for the position of the warm air water tank to flow out, the warm air water pipe can also be installed, 2, and then start the car, wait for the fan to work, the temperature of the upper and lower water pipes is the same, the fan heat dissipation is hot air, this is no problem, it is normal.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, the engine water tank exhaust air, 1, this is no air exhaust, he started the self-Na He dynamic grinding rolling circulation air exhaust air, you can disassemble the warm air water pipe to exhaust the air, and wait for the warm air water tank position to flow out of the eliminator, the warm air water pipe can also be installed, 2, and then start the car, wait for the fan to work, the temperature of the upper and lower water pipes is the same, the fan heat dissipation is hot air, this is no problem, it is normal.

Can it be to start the exhaust air directly?

That's right. Add automatic circulation and exhaust air.

Summary. Hello dear Audi A4L water tank water exhaust air method steps are as follows; 1.Fill the water tank with coolant:

First, make sure that the engine has been completely cooled. Then open the tank lid and pour in enough coolant until the tank mouth almost overflows. 2.

Open the tank drain valve: Find the tank drain valve, open it until the coolant flows out of the drain valve, while observing whether there are air bubbles in the coolant, and if so, continue to inject coolant into the tank. 4.

Close the tank drain valve: When the coolant is discharged, close the tank drain valve and continue to inject the coolant to the normal water level. 5.

Check the water temperature gauge and water tank cover: Check whether the water temperature gauge is normal, if the water temperature gauge pointer exceeds the normal range or the water tank cover is deformed, it should be dealt with in time. It should be noted that when exhausting air, the engine and parts that are susceptible to high temperatures, such as insulating sleeves and suction pipes, should be turned off to avoid burns.

At the same time, the operation of exhaust air needs to be carried out under the guidance of professional technicians to avoid damage to the parts of the car. Dear, <>

How to exhaust air from Audi A4L water tank.

Hello dear Audi A4L water tank water exhaust air method steps are as follows; 1.Fill the tank with coolant: First, make sure the engine has completely cooled down.

Then open the tank lid and pour in enough coolant until the tank mouth almost overflows. 2.Start the engine:

Find the drain valve of the round water tank, open it, and wait until the coolant flows out of the drain valve, while observing whether there are air bubbles in the coolant, and if there is a collapse, continue to inject coolant into the water tank. 4.Close the tank drain valve:

When the coolant is drained, close the tank drain valve and continue to inject the coolant to the normal water level. 5.Check the water temperature gauge and tank lid:

Check whether the water temperature gauge is normal, if the water temperature gauge pointer exceeds the normal range or the water tank cover is deformed, it should be dealt with in time. It should be noted that when exhausting air, the engine and parts that are susceptible to high temperatures, such as insulating sleeves and suction pipes, should be turned off to avoid burns.

Idling oh dear,

Summary. Dear, how to exhaust air from the Mercedes-Benz S400 water tank:

Set the vehicle on fire, preheat it for 5 to 10 minutes, wait for the coolant to go down a little after the cooling fan turns, then fill up the coolant and close the water tank cover.

How to exhaust air from the Mercedes S400 water tank.

Pro, how to exhaust air from the Mercedes-Benz leaky Sakura S400 water tank: turn the vehicle on fire and return to the letter cluster, preheat it for 5 to 10 minutes, and wait for the coolant to go down a little after the fan turns on the cold stove, and then fill up the coolant and cover the water tank cover.

Pro, the operation method of exhausting air in the water tank: release half of the coolant in the water tank, start the engine to keep idling, and slowly add the coolant until it is full. The manifestation of air in the car water tank is actually that the antifreeze in the water tank has a large air blockage, which will cause the coolant to flow poorly.

Automobile water tank generally refers to the radiator, the radiator belongs to the automotive cooling system, the radiator in the engine rolling front Xiao water cooling system is composed of three parts: water inlet chamber, water outlet chamber, main piece and radiator core. There are two main types of automotive radiators: aluminum and copper, the former is used in general passenger cars, and the latter is used in large commercial vehicles.

Good luck every day! <>
