A story illustrates the benefits of coolant 20

The coolant is given to the engine to balance the temperature, and it can guarantee that your engine is working at a normal temperature.

As for you saying, 'There is no coolant, the benefit of adding coolant?' The question I have is: If your car doesn't have coolant, can you still drive it? Huh .

If you have coolant, add a coolant with a high boiling point or a low freezing point? Mine is: The benefits are definitely there.

A high boiling point means that when the coolant in your car reaches the temperature it is subjected to or is higher than that standard, it will cause the boiling phenomenon. If the pot is boiled, then the problem is very serious! (Hint:.)

Especially in the case of running at high speed or high speed, if your coolant is of poor quality or for a long time, it is easy to boil) low freezing point means that when the coolant in your car reaches the low temperature it is subjected to or is below that standard, hehe. Then your car may not catch fire for a long time. You should know that, right?

True story. How so? I do repairs in a 4S shop.

I often go out to rescue the car!! I often encounter boiling pots, and the coolant inside is sprayed out! And there is also a thick smoke.

It's been a rare occurrence lately because we have Airwin waterless coolant, a lifelong coolant. Customers have switched to that. As for Aiwen, I won't introduce you to more, lest some people say that I am the childcare of that Aiwen.

As for the low freezing point, I haven't encountered it because I'm in the south!

Thank you. If there's anything else you need my help with, just ask.

The coolant has the effect of cooling, anti-corrosion, anti-scaling, anti-freezing and heat dissipation.

Cooling is the basic function of coolant. The engine generates a lot of heat when it works, 60% of which is dissipated into the surrounding space through the cooling system. Anti-corrosion, the radiator, water pump, cylinder block and cylinder head, water distribution pipe and other parts of the cooling system are composed of steel, cast iron, brass, copper, aluminum, solder and other metals, due to the different electrode potentials of different metals, electrochemical corrosion is easy to occur under the action of electrolyte; At the same time, the acid products formed after the decomposition of diools in the coolant and the acid exhaust gas after fuel combustion may also penetrate into the cooling system and promote the corrosion of the cooling system.

In order to reduce the formation of scale, the coolant requires the use of softened deionized water during both production and filling. In order to keep the car in low temperature in winter, the engine coolant is added with some substances that can reduce the freezing point of water as antifreeze to keep the cooling system from freezing in low temperatures.

The functions of car antifreeze are:

1. Prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or cover when parking in the cold winter.

Its main indicator is the freezing point of the antifreeze. When selecting or formulating the antifreeze, its freezing point should be about 10 below the minimum temperature in the region to ensure that the antifreeze does not freeze in exceptional circumstances. Another important function of antifreeze.

Its main indicator is the boiling point. The boiling point refers to the condition that the coolant begins to heat up to the control temperature of boiling under the condition that the cooling system of the automobile engine is in equilibrium with the outside atmospheric pressure, and the engine is kept working at normal temperature. Antifreeze also provides protection against corrosion.

Corrosion is a remote process in which metals are destroyed in the natural environment due to chemical reactions, electrochemical processes, and physical uses. At present, there are six main anti-corrosion metals, namely: steel, cast iron, copper, solder, brass, and cast aluminum.

Most of the cooling systems of modern automobile engines are made of cast aluminum and aluminum alloy parts, so the focus of antifreeze corrosion protection should also be shifted to anti-corrosion of aluminum, and the dissolution, bulging and aging of non-metallic materials such as rubber and plastics in the cooling system should also be considered. Corrosion inhibitors are substances that stop or slow down these processes. Another important function of antifreeze is waterproofing, which is caused by the attachment of insoluble salts or oxide crystals to the surface of the radiator.

After the scale is generated, it not only affects the normal heat dissipation of the radiator, but also is more likely to cause the blockage of the circulation pipe of the cooling system, and the water temperature is too high and seriously affects the normal operation of the engine. The main substances that can produce limescale in the cooling system: calcium sulfate, calcium carbonate, magnesium carbonate, etc., as well as brown calcium phosphate due to improper use.

Calcium and magnesium ions are mainly used in the water in the coolant, so the water quality of the cooling antifreeze must be strictly controlled.

Hello dear, for computers and sensitive electronic components. Due to its high insulation, it can be used for the cooling of high-voltage transformers and high-power electronic components. In the semiconductor industry, FC-77 is mainly used in etching equipment, ion implantation equipment, and chemical vapor deposition (CVD) as a constant temperature coolant.

Due to its low pour point, the FC-77 can be used for thermal shock tests and other tests.

Winter freeze protection. In order to prevent the coolant from freezing after the car is parked in winter, causing the water tank and engine block to burst due to the freezing of the coolant, it is required that the freezing point of the coolant should be about 10 lower than the minimum temperature in the area in case of sudden weather changes.

Corrosion-resistant. The radiator, water pump, cylinder block and cylinder head, water distribution pipe and other components in the cooling system are composed of steel, cast iron, brass, copper, aluminum, soldering and other metals, due to the different electrode potentials of different metals, electrochemical corrosion is easy to occur under the action of electrolyte; At the same time, the acid products formed after the decomposition of diools in the coolant and the acid exhaust gas after fuel combustion may also penetrate into the cooling system and promote the corrosion of the cooling system. Corrosion of the cooling system will cause the downwater chamber, fuel injector spacer, cooling pipe, joint and water tank pipe of the radiator tank to fail, and at the same time, the corrosion products will block the pipeline, causing the engine to overheat or even paralyze; If the corrosion is perforated, the coolant can be severely damaged by the penetration of the coolant into the combustion chamber or crankcase, as when the coolant or water is mixed with the oil, it creates oil and gum that weakens the lubrication and causes the valve, hydraulic valve pushrod and piston ring to bond.

Therefore, a certain amount of anti-corrosion additives are added to the coolant to prevent corrosion in the cooling system. [1]

Waterproofing. The coolant should be circulated to reduce the generation of scale as little as possible, so as not to block the circulation pipe and affect the heat dissipation function of the cooling system. To sum up, you should be cautious when selecting and adding coolant.

First of all, you should choose the appropriate ratio of coolant according to the specific situation. Second, add coolant. Add the coolant with the selected ratio to the water tank to make the liquid level reach the specified position.

Prevent from boiling. Compared with the boiling point of water of 100, the coolant can withstand higher temperatures without boiling (boiling), which meets the heat dissipation and cooling needs of high-load engines to a certain extent.

The role of coolant.

1. Winter frost protection.

2 Anti-corrosion.

3. Waterproof scale. 4. Prevent boiling.

It is very easy to understand from the literal meaning, it is used for cooling, it circulates in our engine water jacket through the pressure of our water pump, to dissipate heat to the engine, it can play a role in anti-boiling, anti-corrosion, anti-rust, anti-freezing and lubrication.

Our commonly used coolant is composed of ethylene glycol aqueous solution plus additives, that is, water + ethylene glycol + additives.

Coolant protects the engine cooling system from rust and corrosion, effectively inhibits scale formation, prevents overheating of the water tank, reduces coolant evaporation, and provides lubrication for the water pump thermostat and other components. The main functions of engine oil in automobiles are: lubrication, cleaning, cooling, rust prevention, and sealing.

Dry friction between metals can cause surface strains on metal parts and require lubrication from the oil to protect them. Under the lubrication of the oil, the metal parts can not be in direct contact with each other, but suspended on the lubricating oil. This is often referred to as the "oil film bearing" effect.

Coolant, the full name should be called antifreeze coolant, which means coolant with antifreeze function, antifreeze can prevent the coolant from freezing and bursting the radiator and freezing the engine cylinder block when the coolant is parked in the cold season, but we have 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.

Hello, the role of the coolant is to reduce the engine temperature and ensure that the engine is working properly.

<> kiss, the steps of adding coolant are: 1. Tighten the radiator and put the water switch, and inject the coolant into the radiator until it overflows, the coolant filling amount is generally 4 to 5L, 2, tighten the radiator nozzle cover, 3, inject the engine coolant into the reservoir until the liquid level reaches the full liquid level line, 4, warm up the engine until the thermostat valve opens, 5, turn off the engine and wait until the coolant cools, 6, remove the radiator nozzle cover and check the coolant level. <>

<> good afternoon, the antifreeze of the car is added once every two years or so, and the method of adding antifreeze is: 1. Open the car after the engine cools down, 2. Open the lid of the antifreeze kettle, 3. Open the radiator drain after lifting the vehicle, and install the old antifreeze after putting it out. <>

Summary. Hello, the role of coolant: 1. Coolant can be anti-scale:

The high-quality coolant is made of distilled water and added with anti-scale additives, which not only does not produce scale, but also has the function of descaling; 2. Anti-corrosion: The coolant not only does not cause corrosion to the engine cooling system, but also has the functions of anti-corrosion and rust removal; 3. The engine antifreeze is basically added with some substances that can reduce the freezing point of water as antifreeze to maintain the cooling system without freezing in low temperature weather. The coolant is composed of three parts: water, antifreeze and additives, and can be divided into alcohol, glycerin, ethylene glycol and other types of coolant according to the different components of antifreeze.

Antifreeze is not only used in winter, it should be used all year round, and the engine antifreeze needs to be replaced every year of driving in the normal maintenance program of the car.

Pro, the coolant can also be changed for the car in two years or thirty or forty thousand kilometers. In order not to block the circulating pipeline and affect the heat dissipation function of the cooling system. It is only when the scale of the tank is below the minimum scale that the coolant needs to be added.

The normal scale of the water tank coolant is between min and max, and there is no need to add water when the water tank coolant is not less than min. When adding coolant to the engine tank of the car, you should confirm that the product is within the expiration date. When replacing, the old liquid should be discarded, and the new liquid should be replaced after the cooling system is cleaned.
