Precautions for car maintenance, precautions for car maintenance

Some motorists often take things for granted in car maintenance, so that they can't extricate themselves from misunderstandings, but they are self-defeating, resulting in damage to parts or mechanical accidents.

Myth 1: The tighter the bolt, the better. There are many fasteners connected with 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, the coupling will 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 slippage or breakage.

Myth 2: The tighter the transmission belt, the better. The water pump and generator of the automobile engine are driven by a V-belt.

If the transmission belt is adjusted too tightly, it is easy to stretch and deform, and at the same time, the pulley and bearing are easy to cause bending and damage. The tightness of the transmission belt should generally be adjusted to the middle of the belt, and its sinking amount is 3 to 5 of the center distance of the pulleys at both ends.

Myth 3: The more oil, the better. If there is too much oil, the crankshaft handle and connecting rod will stir violently when the engine is working, which will not only increase the internal power loss of the engine, but also cause the oil to burn the oil failure due to the increase in oil splashed on the cylinder wall.

Therefore, the amount of oil should be controlled between the upper and lower lines of the dipstick.

Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting or replacing certain parts of the relevant parts of the car, also known as car maintenance.

Three points of car maintenance and seven points of maintenance, which shows the importance of maintenance to the car, and the car needs to pay more attention to several aspects of maintenance:

First, we must develop good driving habits, standardize the driving of vehicles, and take care of vehicles, which can effectively reduce the damage to the car;

2. Develop the habit of regular self-inspection, and at the same time do maintenance according to the requirements, the replacement of three filters and engine oil needs special attention, choose a brand with quality assurance, and try not to change the brand frequently;

3. Deal with abnormal problems in a timely manner, when there is a problem with the car, you must find a store that is familiar with the model, and find an experienced master to judge and eliminate the problem, so that not only the safety of the vehicle is guaranteed, but also the safety of the driver and pedestrians.

<><1. The body should be cared for: there is more wind and sand in spring, and there are many impurities in the air, such as catkins and sand. Fine sand particles can easily get into the engine compartment cover, so it is necessary to clean up the dust around the engine in time and pay attention to protecting the car paint.

The brightness and hardness of the car paint after sealing the glaze will be greatly improved. For some high-quality glazes, the effect on vehicle beauty is very obvious, which can keep the paint smooth and bright for up to a year, and can also prevent acid rain from eroding the car paint in summer.

2. "Brother Dirty" maintenance: The engine will form a thick layer of carbon deposits when used for a long time, corrode the rubber parts in the engine, and affect the normal driving of the car, so it is necessary to clean the engine in time. After cleaning the engine, a layer of maintenance wax is applied to prevent the metal parts in the engine from rusting and the rubber parts from being corroded, which is more beneficial to the health of the car's heart.

3. Sterilization in the car: the temperature gradually rises in spring, which is the season for the multiplication and growth of various bacteria, so special attention should be paid to the anti-bacteria in the car room, so that the cab can be kept dry and hygienic, especially for the car seat cushion, foot mat, steering wheel cover, air outlet These sanitary dead corners should be cleaned to keep the car environment dry and tidy.

4. The wiper should be cared for: the increase in spring rain will inevitably make the wiper bear more responsibility. If the wiper can't brush off the rainwater well, it will bring great danger to your driving safety, so it should be more careful to check and maintain.

The owner can place the wiper switch at various speed positions, pay attention to whether the wiper has vibration and abnormal noise in the work and errand, check whether the wiper maintains a certain speed at different speeds, observe the state of the wipe, and whether the wiper rod has uneven swing or leakage to scrape the phenomenon.

At the beginning of July, the rainy days that have lasted for nearly a month are about to leave Shanghai, and with them will be the scorching summer, in other words, Shanghai is about to enter the "barbecue" mode from the "sea" mode. At this time, in addition to people suffering from various discomforts caused by high temperatures, cars will also experience the test of high temperatures. According to the high temperature weather in many tropical places and countries in the northern hemisphere this year, Jiangsu, Zhejiang and Shanghai may also usher in a red-hot invasion that is rare in ten years this summer.

Regarding summer car maintenance, we can get different information from various sources, of which the Internet accounts for the vast majority. However, in addition to the product manual indication or 4S store regulations, most of the information is fragmented and fragmented, which sometimes makes it difficult for car owners to judge. Based on this, we have sorted out the common maintenance methods, and at the same time, identified the common sense of "mistakes", and added a lot of little-known "cold knowledge" of car maintenance

1. Check the "shoes."

The importance of the tire to the car is self-evident, as it is the only part of the vehicle that comes into contact with the ground, so it is a responsibility to play a high role in terms of performance, safety and quiet fuel efficiency. At the same time, tires are relatively easy to damage consumables, in the summer, due to the constant contact with the hot ground through the sun, tire wear accelerates, the first thing the owner checks is to find out the current wear of the tire.

Each tire has a set replacement mark at the factory, which must be replaced after excessive wear, and in the case of accelerated wear in the summer, if the tire is close to the wear line, it is recommended to replace it. Such early prevention of dust and lead bushes can effectively avoid the occurrence of punctures and other situations. At the same time, due to the heat, the tread is softer, the contact area is increased, the fuel consumption is increased, and the new tire pattern is deeper, which can ensure the grip while saving relatively fuel.

2. Test the oil circuit regularly.

In summer, there are many sudden changes in the weather, and the alternation of cold and heat is obvious, which is a big test for all kinds of oil pipelines mainly made of plastic materials, because in the process of alternating between cold and heat, the aging of plastic materials will be accelerated, and the high temperature of continuous cherry blossoms is a challenge to the pressure-bearing capacity of oil pipelines.

Fuel pipe leakage is very dangerous, but the probability is extremely low, the vehicle will be designed to "leak a little cautious to treat the oil" more in the brake hose and power steering hose, if the former has oil leakage, it will lead to insufficient oil pressure, and then affect the braking effect, and even brake failure will occur in serious cases; If the latter has an oil leak, it will lead to poor steering, which will directly affect the steering ability when driving at medium and low speeds, and thus threaten driving safety.

Generally, the owner of the car excites understands the importance of brake fluid, but the understanding of steering power fluid is insufficient. Compared to brake fluid inspection, steering assistance inspection is more convenient and simple, and if you turn the steering wheel when the vehicle is stationary on an asphalt road with no obstacles to the wheels, it may be that the oil pressure is insufficient and needs to be replenished.

<> "Precautions for Car Maintenance.

1. Oil maintenance.

Generally, the car maintenance mileage is 5000 kilometers or half a year first. The maintenance mileage of some vehicles is 10,000 kilometers or one year first, and the specific maintenance mileage and years are best based on the maintenance manual.

2. Maintenance of air conditioning filter.

The replacement cycle of the car air conditioning filter is generally about 20,000 kilometers, but due to the problem of which book around the town, the replacement cycle may be shortened.

3. Brake fluid maintenance.

The maintenance interval of the brake fluid is 2 years or 40,000 km.

4. Maintenance of antifreeze.

The replacement period of antifreeze is 2 years or 50,000 km.

Some cars are free from replacement for life.

<> "Car Maintenance Precautions.

Regularly clean the bird droppings, dust and other dirt on the body paint; Minor scratches on the paint do not need to be sanded, but minor scratches can be removed with toothpaste. Observe whether the "five oils and three liquids" are sufficient and deteriorate, and pay attention to regular replacement; Regularly clean up stones and other foreign objects in the tire tread, check the wear degree and pressure of the tire, and replace the new tire in time; In addition, the air filter and air filter can be replaced by themselves.

In addition to regular maintenance in the 4S shop, the owner should also develop the habit of daily maintenance, even if the time is very short, it is enough for the owner to carry out a simple maintenance inspection.

First of all, the appearance of the car. If there is bird droppings, dust and other dirt on the body paint, it will cause damage to the car paint over time, resulting in the car surface is no longer shiny. Therefore, the owner must remove the dirt on the surface of the car in time every day.

If there are slight scratches in the car paint, the owner does not have to go to the car detailing shop to polish it right away. In fact, toothpaste can also remove minor scratches. The method is to wash the scratches with water, then take a clean cloth or towel, dip a little toothpaste in a little toothpaste and gently push the scratches repeatedly, and dry them with wet wipes after the scratches disappear or weaken.

When it comes to the interior of the car, "five oils and three liquids" is the main precautions for the daily maintenance of the car. "Five oils" refer to: brake oil, engine oil, and fuel. Transmission fluid, power steering oil. "The "three liquids" are: electrolyte, coolant and glass water.

Then there are car tires, and foreign objects such as stones in the tire tread should be cleaned regularly, because there are often some pebbles and other things embedded in the tires, and these smells can easily cause danger when the wheels are driving at high speeds.

Also, check the degree of wear and pressure of the tires, whether the tires have bulges and cracks. If the tire's wear indicator is visible, you need to replace it with a new one.

The owner's Rizheng Lu Feng is often maintained, which is nothing more than these. Of course, in addition to these, the replacement of air filters and air conditioning filters can also be done by the car owners themselves.

<><1.The maintenance mileage of the first service of a new car is generally 5000 km. In most cases, between 4000 kilometers and 5000 kilometers, you will go to the store to protect the chain 1

The vehicle load capacity should not be too high, it is best to drive around 12 people2 In the choice of road, never take the start.

2.Check your tires and their pressure. If the car is driven for a long time, the tires will wear out, affecting the grip. When driving on the high-speed bus road, there will be a series of shock absorbers on the ground before entering the toll booth rest area.

3.Motor oil protects the moving and worn parts of the car. After 5000 km, the oil in the tank turns black.

This is because the dirt and dust produced by mechanical wear and tear will fall. Oil lumps are formed, so regular oil changes are required. It is best to choose a good quality engine oil, which is conducive to the maintenance of the car.

4.Spring maintenance should first refer to the vehicle instruction manual to check the tire pressure comprehensively. Add or replace coolant in a timely manner. Do not replace it with clean water, add anti-static equipment to the car, so as not to carry static electricity in the human body, and also to avoid static electricity interference or breakdown of some electrical equipment in the car.

5.Check and change the engine oil in a timely manner. The normal operation of automobile engines and other components is inseparable from the lubrication and cleaning function of engine oil.

Therefore, the oil dipstick should be checked in time to see if the oil is normal. There are also a lot of impurities in the air, such as catkins, sand grains, etc.

6.A clogged oil filter can hinder the flow of lubricating oil, resulting in poor engine lubrication and wear, and even tile burning. For this reason, it should be cleaned or replaced regularly, generally every 8000km, and every 5000km3 if the weather is dry.

Clean BatteriesMaintenance-free batteries are commonly used in modern cars.

7.With the approach of summer, the temperature continues to rise, more and more rain, and the problem of car seasonal maintenance is gradually put on the table, and battery electrodes and internal parts are easily affected by high temperature conditions.

<> "Car Maintenance Precautions.

Over the years, the purchasing power of ordinary people in China has increased significantly, coupled with the popularity of the automobile market, as a commodity, cars have begun to enter more people's homes. After buying a car, it does not mean that it is over, and it is necessary to work the maintenance of the car.

1. Speaking of maintenance, today I will talk to you about the places to pay attention to in car maintenance. In fact, the balance of the car's socks is generally determined by the number of driving strokes or the time interval from the last maintenance. Under normal circumstances, every 5000km line, it is necessary to do this routine maintenance, mainly to change the oil, filter and air filter, etc., and the brake disc and brake pads are also the scope of inspection, as well as to detect the condition of the tires.

2. Then in the third year or after driving more than 4w kilometers, in addition to regular maintenance, it is also necessary to clean the key parts of the engine such as the fuel nozzle and throttle, and the transmission oil, front and rear axle oil and antifreeze should also be replenished in time. Finally, there is major maintenance, generally after the mileage has passed 10w kilometers, each part of the car needs to be inspected in detail, including various lines and circuits. In addition to these, you should also check in time when you notice that there is an abnormality in your car.
