Water tankexistcarIt plays an important role in cooling and heat dissipation. In the summer of continuous high temperature in Shanghai, car water tanks are especially prone to some minor faults. Insufficient water level, rusty water tanks, water leakage, etc. will directly cause "pot boiling", that is, the temperature of the water tank reaches the boiling point. At this time, the engine's heat dissipation is poor, the temperature is too high, and the expansion of the parts will reduce the gap between the parts. On the other hand, the viscosity of the oil will decrease when the temperature is too high. In this case, the wear of the parts will increase. If the proper treatment is not done immediately, the engine is likely to burn and cause serious damage.
On-site fault judgment: When the car is driving,Engine coverWhen white water vapor suddenly emerges from inside, or the pointer of the water temperature gauge rises rapidly to the high temperature “H” mark position, it means that the engine temperature is too high.Usually due to insufficient water in the water tank, water leakage or the water tankfanCaused by non-operation and other reasons. Real-time processing:
Step 1: Find a safe place to park immediately, but don't turn off the engine immediately. Let the engine keep idling to continue to dissipate heat, and at the same time, open the engine cover to increase the heat dissipation speed. Note: When the water temperature is too high or even boiling:
1. Don't try to continue driving, so as to avoid major machine damage accidents.
2. Don't try to open the water tank cover, otherwise it is very likely that hot liquid will spray out and cause burns.
3. Do not pour cold water into the engine block and cylinder head, it is likely to cause the cylinder block to burst due to

3. Do not pour cold water into the engine block and cylinder head, it is likely to cause the cylinder block to burst due to sudden cooling.
Step 2: After a period of time, check for water leaks under the car.
Step 3: After the pointer of the water temperature gauge drops to the proper temperature, turn off the engine.
Step 4: Wrap the lid of the water tank with a wet towel, and slowly open the first stepswitch(About 1/4 revolution), after the water vapor pressure is released, completely open the water tank cover, check the water volume and water quality in the water tank, and the fanbeltAre there any exceptions? If the amount of water is insufficient, you should slowly add water to the vicinity of the highest marking line.
Note: If the water tank is leaking or the fan belt is loose or broken, you can call the towing company and wait for the trailer to be rescued. If necessary, you can also wait for the engine to cool down completely and then drive the car to a service shop for repairs at a low speed. Remember, you cannot drive at normal speed, otherwise it is likely to cause permanent damage to the engine.
Daily maintenance of the water tank: Generally speaking, it should be replaced after driving 20,000 kilometers or a yearantifreeze; When there is no antifreeze, do not add tap water. Rust and scaling of the engine water tank are the most common problems.Rust and scale will limit the antifreeze incooling systemThe flow in the air, reduces the heat dissipation effect, causes the engine to overheat, and even causes the engine to be damaged. The oxidation of antifreeze will also form acidic substances, which will corrode the metal parts of the water tank, causing damage and leakage of the water tank. The solution to the water tank failure is mainly in the routine inspection on weekdays. The water tank should be checked frequently for leaks or rust. It should be cleaned, replaced or added with antifreeze to increase the boiling point and prolong the service life.
Generally speaking, the antifreeze should be replaced after driving 20,000 kilometers or one year.This can increase the boiling point, prevent the generation of scale, rust and improve the heat dissipation effect, so thatWater pumpProduce lubrication, avoid and eliminate the damage of the engine caused by the instant high temperature caused by bubbles. When the antifreeze is lacking, try not to add water to supplement it, especially in summer. Because the chlorine contained in the tap water will corrode, rust, and block the water tank, engine and other systems, the cooling system will not be cooled smoothly, and the engine temperature will be too high and the vehicle will be damaged.
