Why isn t it recommended to add tap water to the car?

There are minerals in the tap water, which is easy to rust, which damages the engine cooling tank, and the freezing point and boiling point of the tap water are low, which is easy to freeze in winter, and the heat dissipation is slightly bad, and the car is very hot, and the high temperature damages the engine.

It is not recommended to add tap water to car glass water and coolant, first of all, glass water, add tap water to clean the effect is not good, tap water will produce scale for a long time, will clog the nozzle, bring unnecessary trouble, and the freezing point of water is 0, it is easy to freeze in winter, and freeze the water tank! You can add purified water and alcohol!

Then the coolant plus tap water is not good for long-term use, there is no problem with emergency use, but replace the coolant in time, find that the coolant is less at high speed, the water temperature rises, you can save the emergency plus tap water, but go back to replace it in time, secondly, the cooling effect of tap water is not as good as coolant, and it will freeze in winter, and the pipeline will be frozen! So it's best to use a car-specific coolant!

The first is that when the antifreeze is added with water, the boiling point of the new antifreeze will be reduced! The car is likely to be boiling! The main thing is that the boiling point of water is 100 degrees!

And antifreeze is generally above 110 degrees! Adding water is equivalent to diluting antifreeze! The boiling point of the new antifreeze will be lowered!

Then the boiling phenomenon occurs!

At the same time, the freezing point of antifreeze after adding water will rise, and the freezing point of general antifreeze is minus 25 degrees! After adding water, the freezing point of the new antifreeze rises, which will rise to about ten degrees below zero, so in many cold places, it will cause the antifreeze to "freeze"! Cause serious damage to the water tank or radiator!

Another point is that after adding water, the proportion of anti-rust additives in the antifreeze is out of balance, and the anti-rust function decreases! At this time, it is easy to produce "scale"! There is also the "corrosion" of the radiator, and even the seepage!

It can be seen that when the antifreeze is missing, you can add an appropriate amount of distilled water, but you must not add tap water directly, because tap water is easy to produce scale and block the water pipe; You can add an appropriate amount of distilled water, but only in moderation, not too much

You can't fill your car tank with tap water. Because tap water contains a variety of minerals and salts, it is easy to corrode and scale the cooling system, damage the cooling system, affect the heat dissipation effect, and even block the cooling pipe, resulting in a series of undesirable phenomena, causing premature damage to the water tank and shortening the life of the engine. For this reason, it is best to use distilled water when using water as the coolant.

Antifreeze contains additives to improve the performance of the three proofs, and mixed tap water can also be used, and the cost is also cost-effective. However, there is still the problem that tap water is prone to limescale. Moreover, the antifreeze additive is a constant dosage, and after dilution with tap water, it reduces its effect, and the result will be a waste of antifreeze and no anti-rust effect.

The role of the water tank:

Heat dissipate heat from the working engine to prevent mechanical overheating and metal expansion affecting the work. The full name of antifreeze is antifreeze coolant, which means coolant with antifreeze function, which can prevent the coolant from freezing and bursting the radiator and freezing the engine cylinder block or cover when the coolant is stopped in the cold winter.

Do not add tap water to the car water tank, because tap water contains a large number of micro metals, we often use a kettle to boil water to know that the kettle will be attached to a layer of scale, then tap water added to the tank will also produce scale, so scale will block the water channel of the water tank, resulting in the waterway is not passable, the engine can not be cooled, and the engine will be seriously caused to pull the cylinder. So it's best to add antifreeze, because antifreeze can protect the engine and make the car dissipate heat effectively.

What kind of water should be added to the car water tank? Many people don't know, the master will give you the answer!

It is recommended not to add tap water, but it can be added in case of emergency, but be sure to replace the antifreeze afterwards, because there is scale in the tap water, which is likely to cause rust and blockage of the vehicle's waterway.

Antifreeze has a boiling point above 120 degrees Celsius, while water has a boiling point of only 100 degrees Celsius. The use of antifreeze prevents the car from "boiling" in the summer. Replacing antifreeze with water is prone to limescale and needs to be replaced frequently, but using antifreeze does not have such worries.

Water can corrode the cooling system to a certain extent, and antifreeze contains anti-corrosion and anti-rust additives. Therefore, for the most fuel-efficient family cars, antifreeze should be used in summer, and tap water should not be used instead of antifreeze. Or replace the coolant with coolant instead of water.

Of course, sometimes when driving on the road, you find that the temperature of the vehicle's water temperature gauge is too high, and the coolant cannot be replaced for a while. This isn't a big problem for the time being, but it's best to replace the coolant later.

Radiators belong to the cooling system of automobiles. The radiator in the engine water cooling system is composed of three parts: the water inlet chamber, the outlet chamber, the main board and the radiator core. The radiator is divided into three installation methods: the same side in, the same side out, the different side in, the different side out, and the lower in and out of the group.

Either way, keep the number of tubes or pieces as small as possible. The more pipe fittings, not only the cost will increase, but also the hidden dangers will also increase.

It is wrong to replace antifreeze with tap water.

1. The boiling point of antifreeze is above 120 degrees Celsius, while the boiling point of water is only 100 degrees Celsius.

2. Replacing antifreeze with water is easy to generate scale, which needs to be replaced frequently, while the use of antifreeze does not have such worries.

3. Water will have some corrosion on the cooling system, and the antifreeze contains anti-corrosion and anti-rust additives. Therefore, for the most fuel-efficient family car, you still have to use antifreeze in summer, and do not use water from land to replace antifreeze.

Correct approach: Replace or replace coolant with coolant, not water. Of course, sometimes when driving on the road, you find that the temperature of the vehicle water temperature gauge is too high, and you can't find the coolant to replace it for a while, you can find some bottled pure water to replenish it temporarily, which is not a big problem for the time being, and then you still have to replace the coolant as well.

No. The car water tank must be filled with special water tank water or qualified antifreeze.

Reasons: 1. Tap water produces more rust than antifreeze, although antifreeze will not be a little rust, but it is much slower than tap water, which is beneficial to the smoothness of the engine waterway;

2. If the area is often below zero degrees Celsius in winter, then using antifreeze can make the water tank freeze less easily after coming down overnight, especially the better antifreeze;

Expand your knowledge:

1. The function of the water tank is to dissipate heat from the working engine, prevent mechanical overheating, metal expansion, and affect the work;

2. Different car manufacturers will have different recommended replacement cycles for the original antifreeze, but most of them recommend that car owners replace the vehicle antifreeze every 2 years, and some manufacturers show that the replacement cycle of their original antifreeze is 4 or 5 years. But no matter what, in short, it has to be replaced, which is nothing more than the length of the replacement cycle;

3. Water tank boiling treatment: When the water thermometer is observed to rise during driving, you can choose the nearest safe area to park, and immediately turn off the engine and open the hood to help the engine dissipate heat.

Generally, the temperature of the engine will return to normal after about half an hour, and you can carefully check the water tank scale and fan for damage. If the tank is short of water, you can add purified water or antifreeze after cooling for a period of time, you can't add cold water directly, and be sure to open the lid of the water tank with a wet towel to prevent water vapor burns.

It is possible to add water, but it is not recommended to add water to the tank, because it will corrode the tank if you add water for a long time

1. In summer, some people often think that antifreeze is not needed, and many people use ordinary tap water instead. Be careful: Experts point out that this is not appropriate.

Because preventing freezing, preventing freezing and cracking of cylinders and radiators is only the most basic function of antifreeze, antifreeze also has other important functions, such as anti-boiling, waterproof, anti-corrosion, etc.;

2. The use of antifreeze in summer can effectively prevent the water tank from "boiling", and the use of antifreeze throughout the year can prevent scale formation in the water cooling system and inhibit the corrosion of various metals. Usually the driver friends ignore the harm of "scale", in fact, the harm of scale to the car is quite large, the thermal conductivity of scale is very small, is 1 25 of cast iron, 1 50 of brass;

3. The thermal conductivity of the coolant is greatly reduced after the scale brother is cleared, the engine temperature rises, and the corrosion is aggravated, which promotes the increase of scale, forming a vicious circle, and the scale may also block the pipeline of the cooling system, causing greater accidents, according to relevant domestic data reports, in the maintenance work of the normal use of automobile engines, 6% of the engine cooling system fails, and the main reason for the failure is the corrosion of scale and metal parts;

4. It can be seen how harmful the corrosion of scale and metal parts is to the engine water cooling system, so the perennial use of high-quality antifreeze can not only effectively protect the car water cooling system, but also effectively save money.
