How to maintain the car in hot weather

In hot summer, most people like to drive when traveling. Indeed, driving can not only reduce sunlight exposure, but also save time. But the problem of driving is also obvious, that is, parking outside the car. The temperature is very high at noon in summer, so parking the car outside for a long time will definitely have a certain impact on the car itself. Such as car puncture, car spontaneous combustion, car paint damage, car boiling and so on. So, how to maintain the car in hot weather in summer? Influence of high temperature on automobile

1, brake failure

When it is hot every day in summer, it is also the time when the brakes are most likely to fail. In addition to the conventional brake pads being too thin and difficult to brake, there are other reasons that will cause braking failure. For example, brake fluid is easy to evaporate in high temperature environment, forming air resistance in brake pipeline, and brake pads are also easy to be ablated, resulting in brake failure. Therefore, the braking system should be checked and adjusted in time in summer to ensure good braking performance. The new car should be stopped for a long time to cool down, but cold water should not be poured in case the brake pad hub is too brittle and broken.

2. The paint is damaged

Car paint is afraid of fire and sun. Long-term exposure will make it old and wrinkled. Sunlight and ultraviolet radiation will rust the car paint, leaving small black spots or yellowing. Car wax itself does not enhance hardness and resist ultraviolet rays. Therefore, when you park, try to avoid direct sunlight.

The tire of this car is flat.

Summer is also a period of high incidence of flat tires, and it is easy to change tires, but not everyone can bear the car accident after flat tires. Therefore, in summer, we must guard against car puncture and check the tire pressure of the car regularly every week; Be sure to remove impurities from tires; Prevent the speed from being too fast; Avoid sudden acceleration and sudden braking; Replace the tires in time.

The car is boiling.

Automobile boiling usually refers to the situation that the working temperature of the engine of the automobile is too high within the normal working temperature range, which affects the normal work of the machine and damages the machine. There are many reasons why cars boil. In addition to high temperature weather, the overload operation of air conditioner and the failure of cooling elements will also lead to boiling in the car. A comprehensive inspection of the automobile cooling system is the primary method to prevent boiling. Check whether the cooling fan works normally, 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 addition, the water contained in ordinary coolant 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.

5. The body is overheated

In summer, the ambient temperature is high, and the engine is easy to overheat when driving for a long time. Therefore, the owner should strengthen the inspection and maintenance of the engine cooling system, including water tank, thermostat, water pump and fan. , and timely supplement cooling water. When the water temperature exceeds 100℃, stop in the shade to cool down, let the engine run at idle speed, and open the hood to facilitate heat dissipation.

6, poor lubrication

When the temperature is Shangsheng Gao, the viscosity of engine oil decreases, and the oxidation resistance becomes worse, which leads to poor lubrication and further increases the mechanical wear of automobiles. Therefore, it is necessary to regularly check the oil quantity and quality in summer, add or replace it in time, and clean the oil filter and radiator in time to ensure smooth oil passage and good heat dissipation, and try to avoid engine overload. Mechanical wear caused by insufficient engine lubrication is generally a big problem, and everyone should pay attention to it.

7, car water

Summer is also a high incidence period of automobile flooding, and automobile flooding and automobile spontaneous combustion are equivalent to two major disasters of automobiles. After flooding, the function failure and the rate of preservation of the automobile are greatly reduced. Automobile rust, mechanical instability, engine failure rate will rise sharply. Therefore, we must guard against the flood of cars in summer. What you can do is to stop according to the weather, don't stop in low-lying areas when it rains heavily, and buy flood insurance.

How to maintain the car in hot weather

1, paint protection cannot be ignored.

Generally, car owners mention car maintenance, usually replacing consumables such as three filters and engine oil. In fact, the most important thing to love a car at high temperature in summer is

Protect the car paint. Car paint is like ten thousand clothes we wear in Qian Qian. It is the face of men and women! The issue of face is always the most important.

Therefore, before the big sun in summer and the occasional thunderstorm kill the car paint, you should put some energy into washing the car often and waxing it regularly, but if you want to wash your car yourself, don't choose to wash it at noon when the sun is maximum, but wash it in the early morning or evening. If the money is not bad, I suggest that you can also make a higher-end atmospheric paint surface for sealing or coating, giving the car paint a sense of security!

If the paint surface is "injured", it can't be ignored. Scratches and dents in car paint must be repaired in time to avoid "harm to nature"!

2. Cleanliness is the first priority.

It's hot every day in summer, so it's very important to do a good job in car washing. You should always open the window for ventilation and clean the outside and inside of the car regularly. You can scrub yourself with disinfectant when cleaning. If you have time, you can also go to a special maintenance shop for ultraviolet irradiation or high-temperature disinfection and sterilization. However, it must be noted that the air disinfection in the car is carried out when there is no one in the car. After disinfection, open the window for ventilation for 5 ~ 6 min, wipe the facilities in the carriage with water, and then dry them with clean cotton cloth to remove the residual disinfectant.

3, the use of air conditioning has a knack.

In summer, the temperature inside the car is often very high. So, don't turn on the air conditioner immediately when the car starts. It will be better to open all the windows for 3-5 minutes before turning on the air conditioner. If the engine is under heavy load for a long time, the air conditioner should be temporarily turned off. When cooling, it is best to blow the wind direction of the air conditioner upward, because the cold air will sink, and the wind direction file is best to choose the blowing face file, and the air outlet is best to adjust upward. Finally, pay attention to turn off the air conditioner before reaching the destination to reduce the odor. If it rains during driving, the window will fog easily. You can also blow the cold air of the air conditioner to the glass to disperse the fog.

4. Be careful of your car tires

Whether it is a person or a car, if the foot is not good, it is basically useless. No matter where the road is in summer, it is estimated that an egg will be cooked soon. At this temperature, more attention should be paid to the inspection and maintenance of tires. Tire inspection, if the pattern is worn, it is necessary to replace it with a new tire. At the same time, speeding, overloading or emergency braking are easy to cause tire puncture. Therefore, the tire pressure can be reduced appropriately, or helium gas with more stable physical properties and less expansion can be filled into the tire.
