Hello "If you want to drive the car well, the maintenance operation is indispensable", this sentence is about the importance of maintenance for the vehicle itself. However, those seemingly simple and inconsequential behaviors on a daily basis can cause damage to the car, which will accelerate wear and tear over time, and thus need to spend more money to repair.

Many people like to keep their cars clean and tidy, and then mistakenly think that waxing from time to time can keep the car in good condition. In fact, waxing every three months or so is fine, because there are some abrasives in the wax, and too frequent waxing will damage the paint or accelerate the degradation of the brightness of the paint.

Similarly, it is important to pay attention to the frequency of car maintenance. When the car needs to be maintained once when it travels about 10,000 kilometers or about 6 months, the owner can carry out maintenance according to the suggestions of the manual or the intelligent system reminder.

<> "Since you have bought a car, you should master a certain amount of car maintenance knowledge. Because car owners are not car experts after all, after driving home the car with their hearts and buried love, even if they want to give it the best care, they are often unable to start, and even sometimes overcare, so as to fall into a lot of misunderstandings in the concept of using the car.

The waxing effect of the circle method is poor.

Many people wax the body in a circle, which is not the correct way to carry the liquid. The correct waxing method is to carry out the waxing in a straight line, alternating horizontal and vertical lines, and finally according to the direction of rainwater flow, so as to achieve the effect of reducing the concentric circle halo on the surface of the paint.

Too much oil is easy to break.

When there is not enough oil in the engine oil pan, the friction between the bearing and the journal will be poorly lubricated due to the small amount of oil, which will aggravate the degree of wear and even cause the accident of burning the shaft. However, if there is too much oil, the crankshaft handle and the big end of the connecting rod will be violently agitated when the engine is working, which will not only increase the internal power loss of the engine, but also increase the amount of oil splashed on the cylinder wall, resulting in the failure of burning oil. Therefore, the oil in the engine oil pan should be controlled between the upper and lower scribes of the dipstick.

The bolt is too tight and permanently deformed.

There are many fasteners connected by bolts and nuts on automobiles, and they should be guaranteed to have sufficient preload, but they should not be overtightened. If it is tightened too tightly, on the one hand, it will cause the connector to be permanently deformed under the action of external force; On the other hand, the bolt will be tensile and permanently deformed, and the preload will decrease, and even cause slipping or breaking.

The fan belt is too tight, and the bearing load is large.

As the temperature rises, some drivers think that increasing the tightness of the fan belt can improve the cooling effect of the engine, so they vigorously increase the tightness of the fan belt, resulting in the fan belt being too tight, but they don't know that this practice is wrong. The fan belt should be kept properly tightened, because too tight will overload the bearing, increase wear, increase power consumption, and also bend the pump shaft, elongate and deform the belt, and shorten the life.

The new battery is not charged to shorten the life.

The first charge of the battery is called the first charge, and the first charge has a great impact on the service life of the battery. If you add "water" to use directly without charging, the capacity of the battery is not high, and the life will be shortened; If it is charged directly, it will also shorten its lifespan. Usually, the initial charge of the battery is after filling the electrolyte, and it can be installed and used for about 1 hour with a small current.

The above is a brief introduction to car maintenance knowledge and is for reference only. I don't know how many of the above misunderstandings you have? If there is, then you have to change it quickly. Only by keeping your car healthy every day can you get on the road with more peace of mind.

<><A little bit of car maintenance

If you want to make your car last longer, of course, you have to take good care of it. How often does a car usually need to be serviced? Our car owners know it all.

But car maintenance is not enough, our daily driving habits, as well as the usual use, will also determine the length of your car's life. Here are some tips to introduce you, if you understand them, it will save you a lot of maintenance costs.

Since many car owners have a car, no matter how far they go, no matter how far they are, they like to drive the car, so that the mileage is much more than others.

We know that the usual oil replacement, mainly based on the mileage driven, if you usually use the car more frequently to stare at the frank fan, the odometer goes too fast, the natural oil change will be more frequent.

Generally speaking, if you choose a mineral oil, the replacement interval is 6 months and the driving time is 5000 km. The cycle of synthetic motor oil is 8 months, or 8,000 to 10,000 kilometers.

In addition to changing the engine oil during maintenance, we should also look at the gasoline filter.

If the inside of it is too dirty, the oil supply system is likely to fail, which will also cause the engine to not work properly, so this part should also be replaced during maintenance. When replacing the gasoline filter, there are two situations, the external cycle is 1 20,000 km, and the built-in cycle is 60,000 km.

In addition, if there is too much dust on the air filter, it will also damage the engine, so it is generally 5,000 kilometers or 120,000 kilometers, and this part should also be replaced.

In order to make everyone safer in the process of driving, the brake pads will be replaced for about 30,000 kilometers.

The spark plug is a device that we use to initiate the ignition.

If it is overworn, it will affect the engine start, and depending on the material, the spark plug replacement interval will be different. Generally, the spark plug with a copper core needs to be replaced at 2 3 kilometers, and the platinum core can travel 5 60,000 kilometers.

The tire is the only part of the car that comes into contact with the road.

It is made of rubber, and it is also very susceptible to wear and age during long-term driving. Therefore, in order to ensure the safety of our driving, Jinhong must not wait for a flat tire before thinking about replacing it, generally 5 years or the car travels 80,000 kilometers, the tire will be replaced.

Although the wipers are not used often, they are prone to deterioration when exposed to the sun and rain on the front windshield.

When we travel by car, we naturally put safety first, and it is recommended that everyone replace the wipers once a year or so.

The entire power supply of the car is provided by the battery.

If it fails, it will affect the circuit system, and even cause the car to be unable to use normally, so the battery should also be replaced after 50,000 kilometers or three years.

Many car owners attach great importance to the maintenance of their cars, and will go to the 4S shop every once in a while to inspect and repair their cars. Although the maintenance of the 4S shop is more professional and formal, too many maintenance items are also a headache. Many car owners don't know how to choose some car maintenance problems, and they have an extra expense if they change early, and they are afraid of leaving potential safety hazards if they don't change!

For example, should the transmission oil of the car be changed, and how long is the best time to replace it?

As we all know, the gearbox is one of the important components of the car.

Transmission oil, also known as gear oil, can lubricate the transmission device, extend the service life, and ensure the stability of the transmission system's clean and heat dissipation functions.

If the transmission oil is not replaced in time, it will deteriorate, and the lubrication, cooling performance, and oxidation resistance of the transmission oil will be reduced. As a result, the various parts of the transmission system cannot dissipate heat properly, which burns out the gearbox. The cost of replacing the gearbox can be much more expensive than changing the transmission oil, so we need to change the transmission oil in time!

How often should I change my transmission fluid?

There are two types of transmissions: manual transmissions and self-acting forward-acting transmissions. Generally speaking, manual transmission oil needs to be replaced in time after 6-80,000 kilometers. The automatic transmission oil can be judged according to the actual color of the transmission oil to be replaced.

Everyone's driving habits and car models are different, so we also need to judge whether we need to change the transmission oil based on the actual situation of our own driving spine car.

1. During driving, if you find that the car shifts not very smoothly and the gearbox produces obvious noise, it means that the transmission oil needs to be replaced.

2. In the process of driving, if it is found that the fuel consumption of the car increases significantly and the speed increases slowly, it is due to the accumulation of too many impurities such as iron filings in the transmission oil, which reduces the lubrication capacity of the transmission oil, and the transmission oil also needs to be replaced.

3. When the transmission oil enters the water, the oil is emulsified, or the transmission oil is in a scorched state, emitting an unpleasant burning smell, it will lead to the decline of the heat dissipation function, and the transmission oil should be replaced in time.

Although the service life of transmission fluid is long, we also have to judge whether we need to change the transmission oil according to the actual use of our own vehicles! Learn these car maintenance knowledge, have a spectrum in your heart, and you will no longer have a headache for the dazzling repair and maintenance projects of the 4S shop!

<><Car maintenance knowledge, another trick learned

All kinds of car maintenance tips, see which ones you know:

1. Maintenance

It is important to have your car serviced regularly.

1. Check the tires

Insufficient air pressure will increase the friction between the tire and the ground, and the friction will increase the pressure and increase fuel consumption, so it is necessary to check the tire pressure frequently, and if the tire is worn, the tire should be replaced in time to avoid high fuel consumption.

2. Replace parts

The car must be maintained in time every 5,000 kilometers, and the clutch plates, spark plugs, and air filters will wear out after a long time, which will lead to increased gasoline fuel consumption.

3. Check the brakes

When you go to maintenance, you also need to check the brakes, and if you often use the car, some cars will also have drag brakes (including hand lift brakes), which will also increase fuel consumption.

2. Driving

Driving skills: The transmission of car power, from the engine to the gearbox, and then from the transmission shaft to the drive wheels, so that the car can move forward, the amount of power output depends on the amplitude of the accelerator pedal. If you want to be fuel-efficient, you need to do the following.

The results of the test showed that pressing the accelerator to the end costs 2 to 3 times more fuel than driving at medium speeds. Under normal driving conditions, the amplitude of throttle pedaling can be appropriately reduced. Don't stomp on the traffic light when starting, you can use the power of the old engine to slow down the hail when starting, which can save fuel consumption.

2. Shift timing and selection

When driving a manual car, we must put an end to low-end high-speed or high-end low-speed, and then shift gears when the speed is stable, and the timing should be selected between 2500-3000 rpm as much as possible.

3. Don't speed up the start

When you first start, don't accelerate right away, because it is more fuel-intensive to run at a low temperature than when the temperature rises, so you should run slowly for a few minutes before speeding up.

4. Precautions during the run-in period of new cars

The speed of the new car should not be too high, and the speed should not exceed 4000 rpm, which is the correct driving method during the run-in period.

5. Master the speed

Try to keep the speed at 70-90 km/h, lower or higher than this will increase fuel consumption.
