How do you get rid of limescale in a car s water tank?

The function of the car water tank is to cool the engine and cool it. Because the cooling system of the car is used to dissipate heat from the engine, the common problem of engine overheating is in the water tank. City buses are the most common in our daily lives, and many private cars also break down because of engine overheating.

Main ingredients: food acids, synergists, metal material protectors.

Function: Quick-acting and thorough cleaning of limescale in the body and pipes of the car radiator tank.

Advantages: 1. The use of food-grade raw materials, no corrosion on heat collector tubes, inner tanks, water storage tanks, coated vacuum tubes, sealing rubber ring plastic parts and other components.

3. Absolutely environmentally friendly formula, the cleaning liquid can be directly discharged, strong and efficient, and the descaling effect can be directly monitored.

How to use: 1. Open the water inlet of the car water tank.

2. Add a bottle (300g) of this product to the water storage tank; One bottle (300 grams) for one car water tank at a time

3. Automatic thermal cycle for 20-30 minutes to make the descaler solution fully contact each part;

4. Open the drain and drain the cleaning liquid;

5. After filling the water tank, circulate it for another two minutes;

6. Drain the circulating water, and complete the cleaning and descaling work.

2. Heat the water to about 40 degrees to descale, the effect is better.

Dosage: It is recommended to clean the car water tank every six months to ensure that the car water tank is in good working condition.

Precautions: If it gets on sensitive parts such as eyes and nose, rinse with water.

The cause of the formation of scale Because the water temperature in the tank has been kept at a high temperature (65-90 degrees Celsius), the hydrocarbons in the water will be combined with calcium, magnesium and other ions to form calcium carbonate and magnesium carbonate that are insoluble in water, commonly known as water alkali. Then, as the water continues to evaporate and concentrate, the water alkali content increases and reaches saturation, and scale is formed. Therefore, adding purified water containing high concentrations of calcium and magnesium ions will be more likely to form scale than adding ordinary tap water, so adding this purified water to the tank has no effect on inhibiting the formation of scale in the tank.

Because the thermal conductivity of scale is very low, only 1 25 of cast iron and 1 50 of brass, the scale formed in the lining of the cylinder block and the water channel of the cylinder head, the temperature of the local area rises due to the poor heat dissipation, which will lead to cracks in the weak parts of the engine and deformation of the cylinder head.

It not only worsens the heat dissipation performance of the cooling system, but also worsens the lubrication conditions, increases the engine temperature, and accelerates the wear of the engine system; It also blocks the heat pipe or cooling system pipe, which greatly reduces the heat transfer efficiency and makes the engine overheat directly damage the safety of the driver. 3. Scale cleaning method 1. 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.

2. Ordinary scale cleaning agent: the water tank needs to be disassembled, and the removal is not thorough, 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. 3. Professional car water tank descaler:

It can be cleaned without disassembly, and can also be cleaned without stopping. The special scale cleaning agent can be directly poured into the automobile water circulation system, let it soak, idle cycle or drive for 20-30 minutes (depending on the degree of scaling can be appropriately extended time, generally not more than one hour), the water tank and the 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.

Hello! The scale of the car radiator tank is caused by the use of ordinary tap water, because ordinary tap water has more impurities and is easy to form scale. It is generally recommended to use antifreeze to fill the water tank, the antifreeze has fewer impurities, is not easy to form scale, and the lower temperature in winter is not easy to freeze.

The reason for the formation of scale is that the water temperature in the tank has been kept at a high temperature (-Celsius), so that the hydrocarbons in the water combine with calcium and magnesium plasma to form insoluble calcium carbonate and magnesium carbonate, commonly known as water alkali. Then as the water continues to evaporate and concentrate, the water and alkali content are not.

The engine is turned off and cooled. Open the lid and slowly add the automatic cleaner to the tank, making sure the cooling water level is normal, then tighten the lid. Start the engine, wait for the water temperature to reach normal temperature, and run it properly for 1-40 hours.

If the cooling system has hard scale, the operating time needs to be increased by 10-48 hours. Turn off the engine, drain the dirt to cool the lead water, replace the antifreeze and clean the cooling water. It can be cleaned annually with an automatic tank cleaner.

Water tank descaling tips: 1. Open the oil drain plug at the bottom of the radiator, discharge the coolant into the water digging box, and deal with it properly to avoid polluting the environment; 2. Close the drain plug, inject water into the radiator, then start the engine, turn on the heater control system, add cleaning agent and idle for 30 minutes to ring the bell (or according to the time stated on the cleaning agent bottle). 3. Turn off the engine, let it stand for 5 minutes to drain the radiator liquid, close the oil drain plug, add water to the radiator, and let the engine idle for 5 minutes.

Then inject 50 50 water and glycol antifreeze again with a coolant compound (using the coolant previously used by the car). The engine is in a state of shutdown and cooling, open the water tank cover, gently add the automatic cleaning agent to the water tank, make sure the cooling water level is normal, and close the water tank cover; Start the engine, wait for the water temperature to reach normal temperature, and rotate it appropriately for 1-40 hours. If the cooling system has hard scale, the rotation time needs to be increased by 10-48 hours.

Turn off the engine, drain the dirt cooling water, replace the coolant or clean the cooling water; It can also be cleaned annually with an automatic tank cleaner.

Because the water temperature in the car fuel tank has been kept at a high temperature, the hydrocarbon ions in the water combine with the calcium and magnesium ions of the side limbs to form calcium carbonate and magnesium carbonate that are insoluble in water, commonly known as water alkali. In addition, as the water evaporates, the water alkali content increases and the scale is formed when it reaches saturation. How to rinse limescale with a car tank:

1. General detergents cannot completely remove scale and acidic substances in the waterway. In some cases, large limescale will turn into foam and fall off, but this will clog the waterway, and sometimes the tank will be removed for cleaning. 2. Use high-quality and powerful detergents, which can be cleaned without decomposition.

It can also be cleaned without stopping. The scale will become a powder that floats in the coolant and does not clog the water channels in the engine. When buying an oil tank cleaner, never be cheap; 3. To avoid the generation of scale, we must pay attention to the selection of coolant for the storage tank.

Many people don't pay attention to the use of coolant and its advantages and disadvantages. Usually, only ordinary water is put into the tank, which can cause the accumulation of limescale. A good antifreeze not only has a low freezing point, but also has a variety of other additives that can suppress foam, rust, electrolysis, and water scale, so it is necessary to carefully choose a coolant that is beneficial to the storage tank.
