How to clean the car water tank? What are the experiences of how to clean the car water tank

As a liquid circuit for engine heat dissipation, the water tank can absorb the heat of the cylinder block, prevent the generator from overheating, have a larger specific heat capacity of water, and the temperature rises not 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 uses water as a heat carrier to conduct heat, and then dissipates heat in the way of convection through a large area of heat sink, the efficiency is relatively high, and the cooling effect is more uniform.

How to clean up limescale.

If the car water tank is fouled, it can be cleaned and descaled with a tank cleaner. Conventional cleaning agents cannot completely remove limescale and acids from the waterway, and sometimes large pieces of limescale can be soaked off, but this will clog the waterway, and sometimes the water tank must be removed for cleaning. If you use the best powerful cleaning agent, the scale will appear as a powder suspended in the coolant and will not clog the water channels in the engine.

So when buying a tank cleaner, don't just try to be cheap.

Manual cleaning method: the car water tank needs to be disassembled, and the scale is removed with a manual hammer, scraper, shovel, etc.; The descaling efficiency is low, the labor intensity is high, it is not easy to clean, and it is easy to cause secondary damage to the water tank.

Ordinary scale cleaning agent: the water tank needs to be disassembled, the removal is not complete, the odor is large, and the corrosiveness is strong, which is easy to cause the aging of the water tank and shorten its service life.

Professional car water tank descaler: can be cleaned without disassembly, and can also be cleaned without stopping. The special limescale cleaner can be poured directly into the car water circulation system and allowed to soak, idle or drive.

After 20-30 minutes, the descaler inside the water tank and the system is discharged, and the water is added to rinse it repeatedly, which can effectively remove the scale, rust, mud and various harmful substances in the engine water circulation system.

In addition, to avoid the formation of scale, it is necessary to pay attention to the selection of coolant in the water tank. Many drivers don't pay attention to the use of coolant and its merits, and usually just plain water is added to the tank. The most common problems in cooling systems are rust, scaling, corrosion, etc.

The main reason for this is the lack of good antifreeze. A good antifreeze is not only a low condensation point, but also has other added ingredients with various functions, which can inhibit foam, anti-rust, anti-electrolysis and waterproof scale, etc., it is recommended to go to a professional cleaning shop or 4S shop for cleaning. end

Specific steps: Voice.

Car water tank cleaning.

First, make sure the engine is cooling down and stalling. Remove the radiator cap and make sure the engine is cool. If the radiator cover is too hot to touch, it means that the engine has not cooled down;

Second, open the drain plug at the bottom of the radiator and let the coolant flow into a bucket. Coolant should be properly disposed of to avoid environmental hazards;

Third, close the drain plug and fill the radiator with water;

Fourth, turn on the engine, turn on the heater control system (this operation will open the heater control valve), add cooling system cleaner, and leave the engine empty for 30 minutes (or follow the instructions on the cleaner bottle);

Fifth, turn off the engine and let it cool for 5 minutes. Drain the liquid inside the radiator;

Sixth, close the drain plug, fill the radiator with water and let the engine idle for 5 minutes. Then re-inject 50 50 water and glycol antifreeze compounds of the coolant (to use the kind of coolant that the car used before).

Automatic cleaning steps without dismantling.

Voice. Disposable cleaning has become the mainstream of car maintenance, and the following are the steps of automatic cleaning using water tank automatic cleaning agent:

1. The engine is in a state of shutdown and cooling. Open the water tank cover, slowly add the water tank automatic cleaning agent into the water tank, so that the cooling water reaches the normal position, and tighten the water tank cover.

2. Start the engine, make the water temperature reach the normal temperature, and then run it for 1-40h as appropriate, if there is hard scale in the cooling system, the running time needs to be extended by 10-48h.

3. Turn off the engine, drain the fouled cooling water, and replace it with antifreeze or clean cooling water.

4. Clean once a year with the automatic cleaning agent of the water tank. [1]

The easiest way to clean the engine water tank: use a professional car water tank descaler, directly pour the special scale cleaning agent into the car water circulation system, let it soak, idle cycle or drive for 20-30 minutes, the water tank and the internal descaler inside the system are discharged, and the water can be rinsed repeatedly to effectively remove scale, rust, mud and various harmful substances in the engine water circulation system.

The scale in the car water tank is one of the main reasons for the normal operation of the engine cooling system, if it cannot be cleaned up in time, it will cause damage to the engine parts, and will also increase the fuel consumption of the car. So it is important to clean the tank regularly.

1. Manual cleaning method.

It is necessary to disassemble the car water tank and remove the scale with a manual hammer, scraper, shovel, etc.; The descaling efficiency is low, the labor intensity is high, it is not easy to clean, and it is easy to cause secondary damage to the water tank.

2. Ordinary scale cleaning agent.

The water tank needs to be disassembled, and the removal is not complete, the odor is large, and the corrosiveness is strong, which is easy to cause the aging of the water tank and shorten its service life.

Although there are many ways to clean the water tank, we still recommend that you use a professional car water tank descaler, using a professional descaler to clean, compared to the complicated operation of disassembling the water tank, this is simply the easiest way to clean the car water tank.

If you want to wash it yourself, you can buy a bottle of special water tank cleaning liquid, which is prepared by the manufacturer, pour it into the water tank and run the engine for a while, and let it go, which is safe and reliable. Automotive supplies are available in the market.

The food acid is citric acid, you can wash it with a concentration of 20%, and the metal material protector is a passivating agent, and you can't buy a small amount.

Food Acid【Product Function】Quickly decompose various scale genes in the water tank to achieve the purpose of quickly dissolving all kinds of scale. It is a green and environmentally friendly high-tech product, which can quickly decompose the scale attached to the inner wall of the hot tank and the heating element, without any corrosion on the parts of the water tank, and the cleaned water tank can be free of any residue. He can clean heavy metal content such as chromium, manganese, silver, mercury, sulfate, etc.

You can use it with confidence. 2. Synergist is an agent that plays a role in maintenance and can protect your engine and fuel economy in the water tank or fuel mechanism. It is advisable to choose a better brand.

3. The metal protective agent can lubricate, penetrate, and wear the metal, and the lubricating protective agent can be sprayed directly to the required place. Its plastic bottle will not rust or deteriorate, caution: this product may contaminate clothing or wood.

Note: This kind of stuff has a slight sedimentation during storage, so it is very important to turn the bottle upside down and shake it evenly before or during use.

Warning: Flammable. If swallowed, it is harmful or fatal to the human body. If swallowed, avoid vomiting and rush to the hospital.

Avoid places within the reach of children. Do not store near heat sources, sparks or flames.

1. Open the drain plug at the bottom of the radiator and let the coolant flow into the barrel. Coolant should be properly disposed of to avoid harm to the environment;

2. Close the drain plug, fill the radiator with water, then turn on the engine, turn on the heater control system (the heater control valve will open), add the cooling system cleaner and the air ** engine for 30 minutes (or follow the instructions on the detergent bottle);

3. Turn off the engine and let it cool for 5 minutes. Drain the liquid from the radiator, then close the drain plug, fill the radiator with water and let the engine idle for 5 minutes. Then re-inject 50 50 water and glycol antifreeze coolant compound (using the coolant previously used by the car).

We all know that the water maintenance of the car water tank will directly affect the service life of the car, so at this time, there will be car owners and friends who ask, how often should the car water tank be added?

1.What is a car radiator?

Is the water tank of the car antifreeze, the water tank, also known as the radiator, is the main part of the car 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.

2.Car tank water or antifreeze?

Cars should be filled with antifreeze all year round, and antifreeze has the effect of cleaning the water tank. Adding water will produce scale, clog the water tank, cause poor cooling water circulation, and below zero, the water will freeze, resulting in damage to the water tank and other consequences, increasing maintenance costs.

3.How often should it be replaced?

The shelf life of general car antifreeze is 2 years, and some car manufacturers mark that their original antifreeze can be used for 4 to 5 years, generally 2 years or more than 30,000 kilometers to replace once, it is recommended to replace the antifreeze recommended in their car manual, or the varieties that are being used now, so that the best protection of the car.

Observe the upper and lower scales of the antifreeze kettle, the water surface can be kept in the middle, and it is best to replace it once after the general car has traveled 20,000km. The water level needs to be checked regularly, and there is no need to add more. However, car owners who run long distances should take a look before running long distances.

Special reminder. The car water tank is not water, but anti-boiling and anti-freezing coolant, which cannot be added to tap water, and only a small amount of pure water can be added as a last resort (mineral water is not allowed). As long as the coolant is added between the downline and the upline, it can't be filled, do you get it?

A good cooling system is an important guarantee for the operation of the car. A car's fuel tank is one of the most important components in the cooling system, and it is very important to clean it regularly. It is recommended to clean it on an annual basis.

The cleaning of oil tanks is divided into external cleaning and internal cleaning. The external cleaning is mainly to clean dust and oil, and the internal cleaning is mainly to clean the scale (main ingredients: calcium carbonate and other carbonates).

Exterior cleaning is relatively simple, and can be done by an ordinary car wash, so I won't explain it here. Below, we will share the experience of cleaning the inside of the fuel tank, for reference only: 1. Unscrew the screws on the engine plate and take out the cover; 2. Open the opening of the water discharge and release the antifreeze of the water tank; 3. After opening, tighten the water discharge switch, and replenish the water tank with the special agent for flushing Pei Weixin washing; 4. Dilute the special detergent and add water according to the proportion; 5. Tighten the box cover and sub-box cover, start the engine to idle for about 15 minutes (the water tank has a lot of scale, and it has not been cleaned for a long time, so it can run moderately for a long time); 6. Stop the machine to extinguish the fire, loosen the water switch, and release the mixed wheel liquid of the water tank.

Special attention: If there is too much scale in the water tank, the scale layer is thick, and it cannot be completely cleaned, it is recommended that a professional water tank service provider carry out special cleaning treatment.

The cleaning method of the small water tank of the car is:

1. Stop the vehicle and turn off the engine, open the expansion kettle and fill the water tank cleaning agent after the coolant temperature drops down;

2. Start the engine until the cooling fan works and then idle for 5-10 minutes;

3. Turn off the ignition and remove the front bumper of the vehicle. When disassembling, make sure that all the fixing screws have been unscrewed, and then slowly disassemble from both ends to the middle, and do not break the fixing buckle;

4. Ensure that the coolant temperature is completely cooled, and then discharge the water tank late cleaning agent with the coolant, and finally replace the new engine coolant.

The method of cleaning the vehicle water tank is: 1. Park the car bucket and turn off the car, open the expansion kettle and add the water tank cleaning agent after the temperature of the coolant recedes; 2. Turn on the engine until the cooling fan is running, and then idle for 5-10 minutes; 3. Turn off the car and remove the front bumper of the car; 4. Ensure that the temperature of the coolant is thoroughly cooled, and then discharge the water tank cleaning agent along with the coolant, and finally replace the new engine coolant. It is also possible to remove the tank for cleaning, but this method is a bit troublesome.

First, remove the engine guard by loosening the screws of the engine guard under the driver at the bottom of the car. Then look for the button under the tank to release antifreeze vertically (i.e., marked with a red circle). Trace mill release the button counterclockwise to release the antifreeze in the tank.

After washing, tighten the button below and add the tank cleaner to clean. After cleaning, simply put the parts back in. When opening the expansion lid, it is important to make sure that the temperature of the coolant has been completely cooled, otherwise due to the hot gas pressure in the cooling system, the coolant will splash out the moment the expansion lid is opened, and there is a risk of personal injury.
