Antifreeze in the water tank, add it to the supplement, from which mouth to add

Add antifreeze to the expansion pot in the car's water tank, and if you want to drain it, there is a small switch under the water tank, near the engine oil pan, and you can turn on the machine.

The way antifreeze is added:

1.Unscrew the lid on the top of the water tank first.

2.After emptying the water in the tank, tighten the bolt (the water bolt is under the water tank, you may need to use a plier, and some can be unscrewed directly by hand), and completely drain the water in the previous tank.

3.Use a screwdriver or a suitable wrench to unscrew the small drain screw on the thermostat (on the thermostat, the one with a diameter of about 8 mm, depending on the car).

4.Add antifreeze to the water tank, add the small water drain screw on the thermostat to running water, that is, tighten the small water drain screw on the thermostat.

5。Continue to add antifreeze to the mouth of the tank until you can't add it, and then unplug the rubber air drain tube next to the tank cover.

6.Start the engine, generally step on the throttle to more than 3000 rpm, until the radiator fan rotates to dissipate heat, that is, loosen the throttle, (at this time the water at the mouth of the water tank will drop some) let the engine idle running, and then continue to add antifreeze to the mouth of the water tank, until the pipe of the exhaust air flows, let the water flow for about 3-5 seconds, that is, plug in the tube of exhaust air, and then step on the throttle to more than 3000 rpm, that is, loosen the throttle, let the engine idle running, and then add antifreeze to the mouth of the water tank, add until it can not be added again. (Be sure to repeat this procedure once, otherwise there will be bubbles in the circulating tube of the engine body, which will seriously affect the heat dissipation of the engine, and be sure to exhaust the air).

7.Tighten the tank cap and am done.

Hello, the vehicle only needs to observe when adding antifreeze and compensate for the height of the bucket level.

Hello friends, under normal circumstances, you need to add it to the auxiliary kettle of the water tank, and keep enough antifreeze in it, so that there will be no shortage in the water tank. I hope I can help you, if you have any questions, please feel free to contact me. BBA Mercedes-Benz BMW Audi Maintenance wishes you a happy life, all the best, and a lot of money!

Open the cabin, and there is a filling port on the upper plane of the cooling tank behind the front bumper.

Summary. You can't add water to this water tank, and the current car water tank uses antifreeze. Water cannot be added to this antifreeze, if water is added, it will affect the performance of the antifreeze, and the freezing point of the antifreeze will rise.

That is to say, when the temperature is relatively low in winter, the antifreeze may freeze, and if it freezes, it will freeze the engine or freeze the water tank. Therefore, the antifreeze in this tank cannot be filled with water.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

You can't add water to this water tank, and the current car water tank uses antifreeze. Water cannot be added to this antifreeze, if water is added, it will affect the performance of the antifreeze, and the freezing point of the antifreeze will rise. That is to say, when the temperature is relatively low in winter, the antifreeze may freeze, and if it freezes, it will freeze the engine or freeze the water tank.

Therefore, the antifreeze in this tank cannot be filled with water.

<> "If there are two ports of water tank and antifreeze in the car, when replenishing antifreeze, add it from the filling port of the antifreeze kettle. Because the function of the water tank filler port is generally used to replace the antifreeze of the whole car or to decompress or exhaust when the antifreeze is in a special state.

Coolant and antifreeze are the same mouth, coolant and antifreeze have a slight difference, antifreeze is not exactly equal to coolant, and coolant is equal to water plus antifreeze. The full name of antifreeze is antifreeze shed teasing coolant, which means that it is a coolant with antifreeze function, but it does not mean that it can only be used in winter, in fact, it is necessary to use grinding antifreeze all year round. Antifreeze has the characteristics of anti-freezing in winter, anti-boiling in summer, anti-corrosion and anti-scaling throughout the year.

Coolant refers to the liquid that can cool the engine, which can be water or antifreeze, if it is water, it is more limited, it will be limited by the season, etc.

When using coolant or antifreeze, it is necessary to replace it regularly, because after a long time, the performance of coolant or antifreeze will change and slowly decay. Therefore, regular replacement can better protect the engine and make the engine run more smoothly.

In general, the replacement cycle of coolant or antifreeze is 2 years or 40,000 kilometers, but this is only for reference, depending on the use of coolant or antifreeze, if the replacement cycle has not yet reached and the coolant or antifreeze has deteriorated, it should also be replaced.

When using antifreeze, remember not to mix two different antifreezes, because different antifreezes have different ingredients and additives, and when mixed together, they may react, resulting in failure of the antifreeze or even damage to the engine. In addition, according to the local minimum temperature, choose the appropriate freezing point of antifreeze to avoid the phenomenon of freezing due to low temperature.

If the car has two mouths, a water tank and antifreeze, when filling the antifreeze, it should be added from the filling outlet of the antifreeze teapot. Because the function of the water tank filling port is generally used to replace the antifreeze of the whole vehicle or the depressurization or exhaust pipe of the antifreeze in a unique situation.

Coolant and antifreeze are the same mouth, coolant and antifreeze have a slight difference, antifreeze is not completely equivalent to coolant, and coolant is equivalent to water plus antifreeze. The full name of antifreeze is antifreeze coolant, which means that it is a coolant with antifreeze and punching effect, but it does not mean that it can only be applied in winter, in fact, antifreeze must be used throughout the year. Antifreeze has the characteristics of antifreeze in winter, boiling in summer, corrosion and scale resistance throughout the year.

Coolant refers to the liquid state that can deheat the engine, it can be water, it can also be antifreeze, if it is water, the limitation is very large, and it will get the time limit.

When applying coolant or antifreeze, it is necessary to replace it regularly, because it has been used for a long time, the characteristics of coolant or antifreeze will change, and gradually the attenuation coefficient will be reduced. Therefore, replacing it on time can better maintain the engine and make the engine run more smoothly.

In general, the replacement cycle time of coolant or antifreeze is 2 years or more than 40,000 kilometers, but this is the practical value, and the actual need to look at the application of coolant or antifreeze.

When applying antifreeze, remember not to mix these two different antifreezes, because different antifreeze has different ingredients and additives, mixing together is likely to produce a reaction, and then cause the antifreeze to fail, and even destroy the engine. It is also necessary to select an antifreeze suitable for the ice degree according to the local minimum temperature to prevent the freezing of the antifreeze caused by the low temperature.

The car antifreeze dust calling liquid is added from the mouth of the auxiliary and chain sen water tank. The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant freezes when parking in the cold winter.

Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round.

At present, more than 95% of domestic and foreign water-based antifreeze uses ethylene glycol, compared with tap water, the most significant feature of ethylene glycol is antifreeze, and water can not be antifreeze. Secondly, ethylene glycol has a high boiling point, low volatility, moderate viscosity and small change with temperature, and good thermal stability. Therefore, glycol-based antifreeze is an ideal coolant.

The role of antifreeze in automobiles

1. Prevent engine corrosion and rust.

2. Descale the engine water tank.

3. Prevent the engine cylinder block from swelling and bursting.

4. Extend the service life of the engine.

Car coolant should not be added with water:

1. The function of automobile antifreeze is to prevent waterproofing. If water is added to the antifreeze, the engine is prone to limescale, which can clog the pipes and affect normal operation and life.

2. The water in the antifreeze is soft, and it should be blended according to a certain standard, so it is not recommended to add water to the car antifreeze.

The role of antifreeze:

When the engine cooling system circulates and flows, the excess heat generated by the engine operation is taken away, so that the engine can run at normal operating temperature.

Steps to change antifreeze:

1. Open the hood of the car after the engine cools down.

2. Open the lid of the antifreeze kettle.

3. Open the radiator drain, put the old antifreeze out and install the drain plug.

4. Pour antifreeze into the antifreeze kettle. Antifreeze can be added, but it is not recommended to add directly, the antifreeze of the car needs to be carefully cleaned before adding the engine cooling system, especially at the turn of the season, the antifreeze needs to be checked, if the antifreeze is insufficient, it needs to be added in time. The main purpose of cleaning before adding antifreeze is to avoid the chemical reaction between the scale in the engine and the antifreeze, and the scale will fall off, which will affect the normal use of the antifreeze.

Antifreeze is the coolant that can prevent the coolant from freezing when parking in the cold winter, while the expansion and cracking radiator and freezing the engine cylinder block, the full name is antifreeze coolant.

Add according to the color, and the color should be consistent.

Antifreeze has a higher boiling point than water, up to about 125 degrees! It is lower than the freezing point of water, up to about minus 30 degrees! And the antifreeze rarely produces limescale and has an anti-rust formula, which is very good for the engine!

In general, adding water will not have too much effect! It is recommended to add coolant as much as possible! Antifreeze is added to the car's water tank!

But now all we see are auxiliary tanks, which are generally added to it, with a scale mark, and a little exceeded.

So is there a difference between antifreeze and coolant? Let's find out.

1.These two things are two names for the same kind of item.

2.Coolant, the full name should be called antifreeze coolant, which means coolant with antifreeze function, antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block when parking in the cold season, but to correct a misunderstanding, antifreeze is not only used in winter, it should be used all year round, the normal maintenance project of the car, every year of driving, the engine antifreeze needs to be replaced.

3.The correct use of coolant can play the role of anti-corrosion, anti-cavitation leakage, anti-radiator boiling, anti-scale and anti-freezing, etc., which can make the cooling system always in the best working condition and ensure the normal working temperature of the engine. If you do not pay attention to it in use, it will seriously affect the normal performance and life of the engine, so special attention should be paid in use.

In the case of normal land raid demolition, it is possible to add about 5 liters of antifreeze, and the car water tank should be added with antifreeze, which cannot be replaced by tap water, for the following reasons: 1. The water in our life can indeed be used to cool the engine, but the water in our life is impure and contains impurities, if the water circulates in the engine, especially when the large circulation flows into the cooling box behind the air intake grille, the impure water Zen He will produce scale to block the cooling system, This situation will lead to the aggravation of powerless wear and tear of the engine, and the high-temperature water is easy to evaporate, resulting in a lack of water in the cooling system, which will cause the cylinder to be pulled and the cylinder head to be deformed, and more seriously, the engine will be scrapped;

2. Water is also a kind of coolant, and it can also cool down the engine, and the coolant filled in the engine is also mixed with the coolant stock solution and water according to a certain standard ratio. However, water alone is a low-grade coolant, which is not only affected by the season, but also prone to scale and rust. The coolant is universal in all seasons, with high quality and excellent effect performance;

3. In a compromise, if your car is really short of coolant for some reason, you can temporarily replace it with distilled water, and the harm of using water instead of antifreeze coolant is not as serious as the market says. But in the end, we have to return to the standardized use of antifreeze.
