The channel source of auto parts is extremely complex, so the price of the same kind of parts in two different channels can be several times or even dozens of times as much. That consumers replace auto parts is to choose the original factory, or choose excellent quality assurance?
What is the water in the car tank?
hudson bros trailer mfg inc claimed that the tank is normally filled with coolant, also known as antifreeze, rather than water. Its liquid level should be kept between min and max. If it is lower than min, it should be added with the same brand and specifications of coolant, or replaced altogether. The choice of coolant is mainly based on the local lowest temperature, the general factory is a full monsoon type. Some owners will think, car water tank, water tank, directly add water, can't it? Small Ann here tells you that you can add water, but it is not recommended to do so, because long-term water will corrode the tank, and remember not to add tap water, because tap water is extremely easy to form scale, scale damage to the car is fairly large, the thermal conductivity of scale is extremely tiny, is 1/25 of cast iron, brass 1/50. With scale, the thermal conductivity of coolant is considerably reduced, the engine temperature rises, and the corrosion is aggravated, which promotes scale increase, forming a vicious cycle.
Two, how to add "water" to the car water tank
A car water tank should pay attention to when adding water, beware of elevated temperature, so it is best to add a cold car. Open the water tank cover or expansion pot cover (different filling seats for different models). In the car, if there is no water in the water tank, you can add a part of the water, and then the car, or water slowly add, until there is water overflow, and then cover the lid. At the same time, you can add a slight throttle to let the water temperature rise. Wait until the cooling fan is working. When the fan stops, cover the lid with a wet towel and slowly open it to see if it is not at the standard water level. If it is not sufficient, add it in place.
Third, how to wash the car's water tank?
Even if you take excellent care of your car, there will be limescale production. At this time you need to wash the tank.
1, manual cleaning method: the car water tank needs to be removed, with artificial hammer, scraper, shovel and so on to remove scale; descaling efficiency is low, labor intensity is elevated, not easy to wash, easy to cause secondary damage to the tank.
2, ordinary scale cleaning agent: need to remove the tank, remove not carefully, odor, strong corrosion, easy to cause tank aging, shorten its service life.
3, professional car water tank descaling agent: can be cleaned without disassembly, but also can be cleaned under the condition of not 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, the water tank and system inside the scale removal agent discharged, adding water repeatedly rinse clean can effectively remove the scale, rust, mud and various harmful substances in the engine water circulation system.
Four, the car water tank boiling. What to do?
After the water tank is boiling, the engine heat dissipation is poor, the temperature is too high, the expansion of parts will reduce the gap between the components. On the other hand, the temperature is too high, the oil viscosity is reduced, in this case, the wear of the components is aggravated. If appropriate treatment is not taken immediately, the engine is likely to burn out leading to serious engine damage.
(1) Causes of car boiling
There are additional reasons for the car to boil, and the main reasons are:
1. The influence of high temperature weather.
2. Overload operation of air conditioning and failure of heat dissipation element.
3, car cooling system failure, such as water tank leakage, lack of coolant, coolant deterioration, coolant circulation system blockage and so on.
(2) Emergency treatment of water tank boiling
When the car is in the process of driving, the engine cover suddenly burst out of white water vapor, or the water temperature indicator quickly rises to the high temperature "H" mark position, that is, the engine temperature is overly elevated. It is normally caused by insufficient water in the tank, water leakage, or the tank fan does not work. Immediate processing:
1, immediately find a safe place to stop, but do not immediately turn off the engine. Allow the engine to continue to dissipate heat while idling and open the engine cover to increase heat dissipation. Note: When the water is too hot or even boiling:
(1) Do not attempt to continue driving, so as not to cause a large accident.
(2) Do not try to open the tank cover, otherwise it is highly likely that the hot liquid will spray out and cause burns.
(3) Do not pour cold water to the engine cylinder block and cylinder head, which is likely to cause the cylinder block to burst due to sudden cooling.
2. After a period of time, check whether water leaks under the car.
3. Turn off the engine when the indicator of the water temperature drops to the proper temperature position.
4. Wrap the water tank cover with a wet towel and slowly open the first switch (about 1/4 revolution). After the water vapor pressure is released, open the water tank cover fully and check the water and water quality in the tank, as well as whether the fan belt is abnormal. If water is insufficient, water should be slowly added to the highest mark near the line.
Note: If the water tank leaks or the fan belt is loose or broken, you can call the traction company and wait for the trailer rescue. If necessary, you can also wait for the engine to fully cool down, and drive the car to the service factory for maintenance at a low speed. Remember, do not drive at normal speed, or you may cause permanent damage to the engine.
