Autumn is coming, the car is always having frequent problems, who knows how to maintain the car in t

Hello, the weather is getting colder in autumn, the engine oil should be paid more attention, the coolant should be checked, the battery fluid should be checked, and some basic maintenance should be done.

The 4S store has 4 activities a year, and there are testing activities before the start of the season every year.

1. Pay attention to weather changes.

In autumn, the climate change is large, and the temperature difference of the pond water is about 10, if the fish are in a bad environment, the breeding effect is definitely not ideal. Therefore, the crab pond should do a good job in the maintenance of aquatic plants, and stocking aquatic plants such as aquatic plants and water floating lotus in the pond to prevent direct sunlight from the whole pond.

2. Carefully cast the bait.

In autumn, the fish reach the peak growth stage, and at this stage, the fish should be well fed. Especially when the water temperature is 20-28, the fish growth is the most vigorous, the feed efficiency is the highest, should seize the opportunity to strengthen the feeding, when the weather is fine, the dissolved oxygen in the water is high, the fish intake is large, can be appropriately more cast; When the weather is hot and humid, the amount of dissolved oxygen in the water is low, the fish feed poorly, and the residual bait is easy to spoil the water quality, so it should be less or no investment. When the water quality is refreshing, the fish are eating vigorously, so they can be cast more; When the water quality is not good, it should be less or no investment.

3. Strengthen water quality regulation and control.

It is often said that to raise a pond of fish first, a pond of water must be raised, and the water quality of the pond is required to achieve "fat, live, tender and refreshing". Due to the large amount of bait, the excrement of fish is also large, which is easy to cause the water quality to deteriorate and produce toxic gases, resulting in the lack of oxygen in the pond water, and causing the occurrence of dead fish in the pond. Therefore, if there is a condition to change the water, it is necessary to discharge an appropriate amount of old water and inject new water in a timely manner according to the color and transparency of the water body; For ponds with low pH, the whole pond should be sprinkled with quicklime solution to improve water quality.

Inorganic fertilizers or biological agents should be used as much as possible when fertilizing, and organic fertilizers should be used less or no at all.

Fourth, adhere to the patrol of the pond to prevent flooding.

Pond patrol work is indispensable in the process of pond fish farming, the pond patrol should be insisted on at least 3 times a day, according to the situation to increase the number of pond patrols, to prevent emergencies. Special attention should be paid to the aeration machine should be opened before the sun comes out in the early morning and the dissolved oxygen content of the water body is low at 2 p.m. on a sunny day, and the aeration machine should be turned on until the floating head phenomenon disappears.

5. Actively prevent and control fish diseases.

Autumn is the season when fish diseases are endemic and prone to bacterial diseases such as gill rot and enteritis and viral fish diseases such as hemorrhagic diseases. The prevention and control of fish diseases should be based on the principle of "prevention first, supplemented by first, prevention of disease, and early treatment of disease". Keep the environment of the fish pond clean, and when fish diseases occur, the dead fish should be fished out in time to prevent the spread of germs and the deterioration of water quality, and correct diagnosis, timely consultation, and timely consultation with the aquatic technology department in case of incurable diseases.

Sixth, timely listing.

Take advantage of the Mid-Autumn Festival and the National Day to do a good job in the listing of aquatic products, and pay attention to the operation of pulling the net to be light when listing, so as to avoid mechanical damage and death; After fishing, the water quality should be adjusted in time to avoid fish diseases; Harvesting should be done in the morning and evening when the weather is cool, and it is not necessary to start fishing in hot weather and when the water temperature is high at noon.

Hello, autumn car maintenance should start from the following aspects:

1. Air conditioning system.

After a summer of use, our air conditioner has been scarred, the air conditioner filter will breed various bacteria, and the frequency of using the air conditioner in autumn will be reduced. Every time you use it, there will be a moldy smell, and driving in such an environment can easily cause the human body to get sick.

In summer, there is a lot of rain, and some of the splashed sediment will inevitably stick to the air conditioning condenser, which is easy to rust the air conditioning condenser after a long time, which will have a certain impact on the use of air conditioning.

Second, the cooling system.

In autumn, the weather is gradually getting cooler, in order to avoid the impact on the car cooling system due to the sudden drop in temperature, it is necessary to pay attention to the antifreeze in time. Some car owners and friends like to use tap water instead of antifreeze in summer, solemn reminder: be sure to replace antifreeze in autumn!

It should be noted that the replacement cycle of general antifreeze is two years, and the engine cooling system should be cleaned before replacing antifreeze.

3. Braking system.

The autumn climate is very humid, and the long-term rainy weather will cause the air to be wet for a long time, and at this time, some water vapor is easy to adhere to the brake pads, which can easily lead to the weakness of the car braking system. It is necessary to check whether the braking has weakened or deviated, and whether the pedaling strength of the brake pedal has changed, and it is necessary to clean the pipeline part of the entire braking system in time.

Fourth, lubrication system.

After the engine is used in summer, a layer of oil sludge will definitely be deposited inside, which will cause the engine to increase fuel consumption, reduce power, and even cause damage to the engine, affecting the service life of the engine, so it is necessary to take advantage of the change of seasons to thoroughly clean the engine. At the same time, it is also necessary to check the use of oil, brake fluid and antifreeze in the engine compartment, add the insufficient ones in time, and replace the expired ones in time.

Now the weather is getting cooler. People often don't adapt to the changing seasons. The upper limit resistance is lowered, the noise immunity is reduced, and the same is true for cars.

Many exterior or interior components, such as car circuits, air conditioning, and tires, are prone to problems. We must take precautions beforehand.

After autumn, it is necessary to do a comprehensive maintenance of the air conditioner, and also pay attention to the maintenance of heating pipes and fans, the autumn FICA climate is cold, and white frost will appear when the temperature is low. This season, pay special attention to whether the exhaust outlet under the windshield is normal or not, so hurry up and find a professional to clean the evaporation tank and air conditioning pipes! If you want to clean up yourself, I'll teach you an easy way.

Turn on the natural wind or hot air, rotate the fan to the maximum, and use the internal and external circulation alternately for about 10 minutes, the maintenance of the automobile chassis in autumn focuses on rust removal and tire inspection, on the one hand, the metal materials of the chassis are easy to rust after burning in the rainy season or high temperature climate, which brings difficulties to safe driving, so it is necessary to remove the rust on the chassis and check whether the TEM scraping chassis falls off.

Regularly check whether the CADA oil has deteriorated according to the time of use, so that it can be replaced in time, and at the same time check the water in the tank, cleaning agent, antifreeze and other water to avoid deterioration. The tire pressure should be replenished so that it is kept within the specified pressure range. At the same time, the tires should also be inspected for scratches, as borracha hardens easily in autumn and winter, appears brittle, and tires are prone to air leakage.

In addition, the treadmill must be cleaned frequently of inclusions.

Do not drag the gears josu288 when the engine is shaking by driving and disassembling the gears; Dragging the gear will cause excessive engine pressure, insufficient energy, incomplete gasoline combustion, carbon accumulation on the fuel injector, affecting the service life of the engine, polishing and waxing refers to the method of polishing the surface of the varnish layer with a polishing machine and then waxing. At the same time dancing with the paint of the car. After all, the varnish layer thinner when polishing.

In the long run, the thickness of the painting will naturally decrease, and the resistance to the outside world will also become weaker.

I would give the car to the 4S shop and let the professionals at the 4S shop take care of the car.

The surface of the car is very damp, the car should be wiped with a dry cloth, and we should also defog it, and we should spray some glass water, so that it is okay.

Autumn car maintenance, on the one hand, in their own car wash, pay attention to continue to maintain the appearance, and secondly, in their own engine and oil selection, choose some good engine oil.

In autumn, you should always check whether the liquid level of brake oil, booster pump oil, antifreeze and other liquids in the engine compartment is within the normal range, and also pay attention to whether the color of the liquid level is normal and whether it is time to replace it. Once the temperature drops sharply, it is very likely to affect the normal operation of the car's cooling system, so it is necessary to change back to antifreeze after autumn.

In autumn, because the temperature is also relatively dry, it is necessary to maintain the chassis of the car at this time, and try to maintain it as comprehensively as possible, so that it is not easy to break down.

<><1. Brake. There was a lot of rain in the summer, so we had to wade through the water to drive. Therefore, in the fall, it is necessary to first check the brakes to see if the brakes are soft, if the brake pedal is heavy, and if the vehicle is mistracked.

Please check the brake pads again at this time and don't joke about driving safety.

2. Inspection of various oils.

Open the hood and observe if the brake fluid, steering fluid, and antifreeze are sufficient or deteriorated. How long does it take to replace? The statement on the Internet is also different, we still need to follow the instructions of the vehicle.

Also, don't replace glass water with tap water. In autumn, glass of water for frost protection should also be prepared. Evil.

3. The tire inspection summer has passed, and the exposed tires have survived another summer. Some car owners are afraid of flat tires in the summer, so they will lower the tire pressure slightly. Now that autumn is here, it's time to make up for normal tire pressure.

When the weather gets colder, the tires get stiffer. Even if it's cold right now, it's time to clean up the small stones from your tires. After cleaning, not only the tire noise is reduced, but also the wheel wear is reduced.

Of course, some small stones are tightly stuck in the rotten tennis. At this point, we can use a special tire stone cleaning tool. This tool not only cleans up small stones stuck to tires, but also can be used as a screwdriver at critical moments, which is particularly convenient.

In addition, you can also find some safety hazards of tires, such as scratches, bumps, cuts, etc.

4. Air conditioning maintenance.

Air conditioners are frequently used in summer, and water droplets are difficult to clean up after mixing with dust and impurities. If you don't care, there will be a terrible smell when the air conditioner is turned on next summer. So go find a professional to clean the evaporation tank and air conditioning ducts.

If you want to do it yourself, I'll teach you a simple method: turn on the natural or warm air, turn on the fan to the maximum, and alternate the internal and external circulation for about 10 minutes.

5. Body maintenance.

As the saying goes, people are clothes, horses are saddles, and the appearance of the body is very important. Some cars have been in operation for a few years and still look like new cars. This is the effect of good maintenance. Autumn is coming, wash your car well, and then polish, wax, glaze, coat.

Autumn maintenance should focus on the issue of temperature, not to mention the routine maintenance at 4S o'clock, but the lock, window, seat slide and other parts are easy to ignore. The 4S stores in these places are not maintained, and if they are not maintained in time, there will be problems such as rust, abnormal noise, freezing, and poor operation. However, you should not use lubricating oil or ordinary butter, as it will have a harmful smell and be bad for the body.

You can choose the fully synthetic lubricating grease used in new Volkswagen cars. This product can be used with tiger head hotolube or Kruber, colorless and transparent, low temperature resistance, durability and odorless. There are 130 grams of small toothpaste tubes in the set, and there are two tubes on the car, which is easy to use.
