There are many reasons for the boiling in the car, such as high temperature weather, overload operation of air conditioner, failure of heat dissipation components ... The high temperature in summer will inevitably affect the heat dissipation of the engine. In addition, driving in urban areas and frequent starting and stopping will aggravate the friction of engine parts and lead to an increase in temperature. In particular, the long-term operation of the air conditioner discharges a lot of heat, which worsens the cooling conditions of the cooling system. If the fan, radiator and other components fail, it will also affect the heat dissipation of the engine, which will lead to a sharp rise in the water temperature of the water tank in a short time until it boils.
Testing in advance is indispensable —— A professional brand of automobile education —— Beijing Dongfang Automobile Maintenance Training School
A comprehensive inspection of the automobile cooling system is the primary method to prevent boiling. Check whether the fan is normal, whether the water tank leaks and whether the coolant is insufficient. If the water tank leaks, it needs to be repaired or replaced in time. If the water tank is short of liquid, it needs to be replenished in time. If the coolant is turbid and deteriorated, it needs to be replaced. In general, the service life of coolant is two years. Usually, car owners should also pay more attention to the changes in the water thermometer in the dashboard. If the indicator of the water thermometer is high, they should drive the car to a large car department store for inspection as soon as possible.
There is no charge for tap water-Beijing Dongfang Automobile Maintenance Training School-a professional brand of automobile education
Many car owners use tap water as engine cooling medium, which may be acceptable in spring and autumn. However, in the hot summer, the working temperature of the engine rises sharply under the scorching sun, and the boiling point of water is only 100℃, which cannot meet the cooling demand of the engine at all. Overheating of the engine will increase the friction between the cylinder liner and the piston, and reduce the lubricity of the oil. Over time, the engine will produce noise, reduce power and increase fuel consumption. Moreover, water electrolysis will produce scale, which will gradually corrode the cylinder block, water tank and rubber parts, leaving the engine "scarred"
Switch to anhydrous coolant-Beijing Dongfang Automobile Maintenance Training School-a professional brand of automobile education
Ordinary coolant is mostly water solvent, and the water contained in it will form a water vapor barrier on the cylinder wall of the engine, which will hinder heat dissipation, lead to engine failure and shorten engine life.
At present, there is an "anhydrous cooling liquid" on the market, which contains no water, avoids the formation of gas barrier layer, and fundamentally overcomes the damage of water or water-containing cooling medium to the engine. As high as the boiling point of 19 1℃, it can quickly eliminate the excess heat generated by the engine, balance the engine temperature, and completely eliminate the hidden danger of engine boiling. —— Beijing Oriental Automobile Maintenance Training School —— a professional brand of automobile education.
When water is boiled, there will be pressure in it. At this time, the lid of the water tank will be opened rashly, and boiling water will splash on people. Adding anhydrous coolant will not happen, which can greatly reduce the probability of pipeline leakage and effectively protect the cooling system. Appropriate temperature environment can obviously improve the engine power and make gasoline combustion more full and complete. Practice has proved that adding anhydrous coolant can save fuel consumption by about 10%, prolong engine life by more than 50%, and greatly reduce engine failures. It can be used continuously for 800,000 kilometers without replacement.
