In the daily maintenance of a car, some drivers will make changes to the car based on their own "experience". However, they do not know that these seemingly correct concepts will not only cause damage to the car, but also seriously threaten their lives. So what are the misunderstandings of car maintenance?

The importance of car maintenance

A car is composed of tens of thousands of parts. With use, the performance of functional components (including lubricating oil) gradually decreases due to factors such as wear, aging, and corrosion. Under normal vehicle driving, such changes gradually occur in many parts. Because no car is used in exactly the same way, it is impossible to predict that every part will have the same wear and aging. Therefore, the factory has stipulated a certain inspection cycle to adjust and replace those components that are expected to change over time or use. This is "regular maintenance." Its purpose is to restore the performance of the vehicle to the best condition, prevent small problems from becoming major problems, and ensure the safety of the vehicle, as well as better economy ...
... and longer service life. Therefore, car maintenance is very important.

The hazards of misunderstandings in car maintenance

In the past ten years, with the great development of automobile materials, maintenance equipment, methods, and modern automobile inspection equipment closely related to this, the overall quality of automobiles has been greatly improved, which has caused important problems in automobile maintenance. Variety.

However, due to the country’s current vehicle management and maintenance system, traditional vehicle maintenance, concepts and other factors, many people’s understanding of vehicle maintenance is still lingering on such things as changing the oil, changing the "three filters", tightening bolts, connecting wires, etc. Do a cleaning adjustment and other traditional "maintenance" level. This kind of "maintenance" can no longer serve the purpose of prolonging the life of Hyundai cars, and it is a misunderstanding of people's understanding of comprehensive car maintenance. Some wrong car maintenance methods not only fail to maintain your car, but may also harm your car, failing to achieve the purpose of maintenance.

What are the misunderstandings of car maintenance?

One: often polish the car

Are the words waxing, coating, and crystal plating familiar? The car wash shop tells you that you can make the car paint crystal clear and look beautiful, so the car owner naturally does not hesitate to spend more money on these so-called "car paint maintenance".

The above-mentioned "car paint maintenance" does not actually maintain the car paint, but damages the car paint, because the car paint needs to be polished before coating and crystal plating. Polishing is actually polishing a layer of car paint. The damage cannot be restored. Moreover, a car paint can only be polished about 7 times at most. Therefore, polishing damages the paint, especially for new cars for coating and crystal plating. It is best not to do it.

Two: frequently waxing the car

Someone said that since polishing hurts the paint, I should protect the paint by waxing the car. Yes, car wax can indeed protect the car paint, but waxing should not be too frequent. After all, car wax is some alkaline chemicals. Frequent use for a long time will also darken the car paint and damage the car paint. I suggest you You can hit up to 3 times in a year.

Three: Buy engine oil only for expensive ones, not the right ones

New car owners often think that expensive things must be good. For those of us who really love cars, buy the right ones, whether expensive or cheap. In particular, many of our foreign engine oils are indeed very expensive, but the viscosity of foreign engine oils is relatively low. Many of our domestic cars require high-viscosity engine oils. This kind of expensive engine oil may not be suitable for us. Increase the engine load.

Fourth, the tighter the transmission belt, the better

The water pumps and generators of automobile engines are all driven by V-belts. If the transmission belt is adjusted too tightly, it is easy to be stretched and deformed. At the same time, the pulley and the bearing are easy to bend and damage. The tightness of the transmission belt should generally be adjusted so that when the middle of the belt is pressed, the sinking amount is 3% to 5% of the center distance of the pulleys at both ends.

Five, the engine idling speed warming up

Many drivers know that when the car is just started, if the engine revolutions are too high, the engine will be damaged due to poor lubrication. However, few people know that if the idle speed is used for a long time to heat up, due to the low speed, the oil pump cannot press the lubricating oil into the lubricating surfaces quickly, and the moving parts of the engine will work under dry friction or semi-dry friction; At the same time, due to poor low-temperature fuel atomization, unburned fuel flees into the crankcase, flushes off the oil film on the cylinder wall, and accelerates the wear of parts. Therefore, in a non-low temperature state, a few seconds after the engine is started, the idle speed should be increased and the engine's lubrication conditions should be improved.

How to properly maintain the car?

1. Check every day

Some people think that it is troublesome to check every day, but check around the car before driving every day, which can effectively reduce the breakdown of the car during driving. The inspection places include: the appearance of the body, tires, dashboard, engine oil, tire pressure, lights, rearview mirrors, and so on. In order to ensure the safe and reliable operation of vehicles, these daily inspections are indispensable.

2. Pay attention to the car wash cycle

Many people say that the car should be washed once a week. Regarding this issue, the editor thinks that it should not be rigidly judged by time, but should be judged in light of the actual situation. For example: on a rainy day, because the rain is acidic and corrosive, you can wash more after the rain; and after a long distance, it is particularly easy to splash mud or sand and dust, which can damage the paint It is also relatively large, so it should be cleaned as soon as possible after a long distance run.

3. Check tire pressure once a month

If the tires are not properly inflated, many problems can occur. One of the consequences is a flat tire, because the air on the tire is slowly used up and your tire may suffer a blow. The blowout occurs at high speed and can be very dangerous. It only takes a few minutes to inflate the tire. In winter, tires tend to lose more air pressure.

5. Maintain the engine

The current car usually does not need to be hot, but when the weather is relatively cold, it is best to run at idle speed for about one minute after starting. Don't let the speed be too high before the water temperature in the water tank is normal. It is important to use the throttle smoothly. After parking, try to reduce the speed of the engine and then turn off the engine. Pay special attention to this for turbocharged ones. If it is a manual transmission car, the speed should be more than 2500 rpm when changing gears, and the same is true for the first gear.

6. Car circuit maintenance

The maintenance of the car circuit system is one of the core contents of car maintenance. Especially for vehicles that have been used for more than three years, it is very important to go to the repair shop to carry out a thorough car circuit system maintenance every year. Experts suggest that if you find that the fuel consumption of your car has suddenly increased, which is not normal, then you should check the car’s oil circuit and circuit. Generally, if the car’s oil circuit and circuit malfunction, the engine will increase its fuel consumption when it is working. The amount of oil increases the natural fuel consumption.

7.Change oil every 5,000 miles

The engine oil is changed every 5000 miles or so. Doing so will make the parts of the engine operate normally. Check the owner's manual to determine how often your oil needs to be changed. Most Dfskcars will have a dashboard light that will tell you when to change your oil.

8. Remove debris from vents

The airways in your vehicle need to be kept clear of branches and other debris that may accumulate. Failure to keep the airway open can lead to dangerous levels of carbon monoxide in the car. This will cause you to pass out before you realize that there is a problem. If you run the heater for a long time, please roll up the windows slightly to keep fresh air circulating through the car.
