Car breakdown is known earlier than car maintenance in summer[汽车修理知识]

It’s the hot summer again,carIn the event of a breakdown, it will break down halfway. I believe that your mood will be even more hot and intolerable than the high temperature and heat. Therefore, it is very important to take care of it in advance. Here are some common sense of maintenance for you to let your car spend the summer in peace.
Careful engine care
Under high temperature conditions, mechanical parts wear, scratches and aging fatigue are more severe than normal temperature.Pay attention to the carcooling systemCooling water, battery water, and engine oil evaporate quickly in summer, so it should be checked and supplemented in time. Engines often drive air conditioning and refrigeration, which consumes 25%-30% more power and 15% more gasoline than usual. So pay attention to engine maintenance in summer.
Tire maintenance
The law of thermal expansion and contraction, righttireThe gas inside is no exception.In catching up with the high temperature for consecutive days, and the car is often exposed to the hot sun, you should pay attention to the car’stireNS. Observe carefully to see if the tire is inflated severely. You can also measure the tire pressure at the inflated place. If necessary, let it out a little to ensure safety. In addition to the general maintenance methods for tires, parking should be on a flat ground and avoid parking the vehicle on a road with sharp or sharp stones. Do not place the vehicle near or in contact with petroleum products, acids and other materials that affect the deterioration of rubber.Don't turn after parkingsteering wheel. Do not pour water on the tires for heat dissipation. It is easy to overheat when driving for a long time or at high speed in summer, and the air pressure increases. At this time, you should stop to dissipate heat.
Prevent excessive evaporation of gasoline and water
At high temperatures, the evaporation of oil and water will increase.At this time, the owner needs to check at any time, pay attentiontankThe cap should be tightly closed, and attention should be paid to prevent oil leakage from the tubing.forWater tankThe water level,CrankshaftThe oil level and height of the tank, the brake fluid level in the brake master cylinder andAccumulatorThe density of the inner electrolyte and the height of the liquid level must be checked frequently. Once it is found to be abnormal or out of specification, it should be added and adjusted in time.
Prevent engine overheating
In order to prevent the engine from overheating, attention should be paid during maintenancefanbeltDo not dip the oil to prevent slipping, and the belt should be kept as tight as possible. During long-distance driving, pay attention to rest in good time, choose a cool place as much as possible, and open the engine hood to ventilate and dissipate heat.
Prevent spontaneous combustion and explosion of cars
The extremely high temperature will greatly increase the failure rate of the car itself. When the temperature is high, the heat dissipation is slow, and the temperature of the automobile water tank is often high, which affects the normal power output of the engine, and may even make the engine unable to work normally. High temperature also causes some parts to expand and deform, the lighter ones will accelerate the wear of the parts, and the heavy ones will burn out the parts.At the same time, long-term use of on-board electrical appliances and air conditioning systems will also cause the car’s circuit system to overheat. If various wires orresistanceThe box does not pay attention to maintenance at ordinary times, and it may even cause spontaneous combustion of the car when it is overheated.
Defendlubricating oilOxidative deterioration
Lubricating oil is susceptible to heat and becomes thinner, has poor oxidation resistance, is easy to deteriorate, and even causes failures such as burning bushes and shafts.Therefore, it should beCrankshaftReplace the summer lubricating oil in the box and gear box, check the quantity and quality of the lubricating oil frequently, and replace them in time.
