In hot weather, what should pay attention to car driving

In July, the hot weather reappeared. In the face of this scorching sun and high-temperature exposure, I don't know if you have a car owner and think about it. Let's take a look at the areas that should be noticed when using vehicles in high temperature weather, and how to make them cooler during driving.

    [High-temperature weather should pay attention to the problem]

     1. The engine water temperature is too high, to add antifreeze.

     Most of the engine water temperature is too high due to the lack of antifreeze, should be parked in the shade cool, do not turn off, let the engine continue to idle speed, open the lid to heat, when the temperature drops and then add antifreeze to the tank, avoid the engine Pouring cold water, because it may cause the engine block burst, can not be repaired. Some vehicle owners simply use tap water instead of antifreeze. This is a wrong practice. Because there are many impurities in the water, it is easy to leave sediment in the engine, water tank, etc. Therefore, water can not be used instead of antifreeze.

     2. Check the cooling system and clean the radiator in time.

     It is also necessary to check whether the “thermostat” work is normal, and do not remove the “thermostat”. Because the "thermostat" is a switch that controls the size of the cooling cycle, the engine operating temperature can be kept within an optimal range, so that the engine will work more power, wear the lowest fuel consumption, if you remove it will cause parts wear, Lower water temperatures will result in lower power and higher fuel consumption.

     3. Clean the water tank and condenser.

     Water tanks and condensers are important components of vehicle cooling systems and air conditioners. As the vehicles are used for a long time, dust, dirt, and dirt will be trapped in the gap between the two, which will affect the performance of water temperature and air conditioning and refrigeration. .

     4. Adjust tire pressure in time.

    The high temperature of the road surface in summer leads to a decrease in the heat dissipation performance of the tire and it is easy to cause a puncture accident. Therefore, the tire pressure should be lowered. After long-distance driving for a period of time, the vehicle should be parked in a cool place to naturally cool the tires. Do not pour cold water so as to avoid deformation of the tires.

    5. Avoid spontaneous combustion of the vehicle at high temperatures.

Spontaneous combustion of vehicles is mainly caused by leakage or oil leakage of vehicles. Improper maintenance of automobiles, aging of parts and components, and breakage of lines can lead to leakage of electricity. The oil tank is prone to oil leaks due to corrosion for a long time. Therefore, avoiding spontaneous combustion at high temperatures also starts with car maintenance.

     6. Frequent use of air-conditioning, air ducts and filter cores should be cleaned in a timely manner.

     In addition, pay attention to refrigerant leakage and poor cooling. This is usually caused by aging of the sealant in the pipeline, abnormal refrigerant pressure, and damage to system components. Also pay attention to the cooling fan's working condition.

     [Cooling automotive supplies]

     1, car refrigerator.

     Car refrigerators are favored by young owners. It can hold mineral water drinks and fruits inside. Just plug the refrigerator's power plug in the car's cigarette lighter to work, and some simple refrigerators do not need power, directly on the ice. The car refrigerator using semiconductor principle is basically dual-purpose. Cooling is used in summer and warm drinks can also be used in winter.

     2. Move the ice pack

     Put the ice bag in the refrigerator for 10 hours, then put the drink into it, and it will reach a low temperature within a short time. The self-freezing function of the ice bag can reach several hours.

     3. Cool pad

     Cooling the chairs in the car in the summer is also a good way to cool down. At present, there are many kinds of cool pads on the market, and there are linen, ice silk, bamboo grass and so on.

     4. The insulation film

     In the hot summer, the owner should consider putting a window under the hot sun and sticking a film that can effectively block ultraviolet rays and heat. The automotive insulation film is divided into front and rear windshield films and side windshield films. Among them, the front windshield is the most demanding insulation film, and the higher the UV resistance index of the insulation film, the better. The optional thermal insulation film on the side windshield is more flexible and the color is also more than half. In addition, the heat insulation effect of the insulation film is not directly related to the color depth. The coating process in the insulation film determines the insulation effect. The key factor.
