Chapter 169: If you don't buy it, you don't need to maintain it

Before getting the primary second-hand car maintenance and maintenance skills, Fang Yuan understood that car maintenance was very simple.

In his impression, the car maintenance is the same as the roadside car wash, use a high-pressure water gun to wash the dust outside the car, clean up the garbage in the car, throw away the dolls, pendants, mats and other things left by the previous car owner, and then brush the wheels, at most a polishing and waxing, and finally the owner pays dozens or even hundreds of dollars to leave, only those local tyrants will seal the glaze, coat, paste the invisible car clothing......

Fang Yuan's understanding of car maintenance is as simple, that is, to change the oil, change the spark plug, change the filter, etc.

After getting the primary maintenance and maintenance skills of second-hand cars, Fang Yuan realized that what he had thought before was too naïve and too simple.

Because the maintenance of second-hand cars is fundamentally integrated.

A car at different times of age, even if it is exactly the same model, the age of the car is different, the maintenance items are also completely different, the water in it is also very deep, and the new car owners will be pitted if they don't pay attention to it.

Fang Yuan made an analogy based on the information provided by the primary maintenance and maintenance skills of second-hand cars, and he divided the second-hand cars he bought into four stages of life.

A new car that has just left the factory is like a baby, and all the organs in its body are like a blank sheet of paper, no smoking, no drinking, and no bad habits.

Except for the problem of the congenital fetal belt, there will be no infectious diseases, malignant tumors, or cancers, which are as holy as angels.

Therefore, normal second-hand quasi-new cars to do maintenance, only need to follow the time and cycle recommended in the maintenance manual of the car, change the oil, oil filter, air filter, air conditioning filter, fuel filter, spark plug, brake fluid, transmission oil, power steering oil, etc.

Of course, these items are not to be done every time, to be determined according to the maintenance manual, for example, a popular Volkswagen model recommends changing the engine oil and oil filter every 10,000 kilometers, the air filter and cabin air filter every 20,000 kilometers, the spark plug every 30,000 kilometers, and the gasoline filter every 80,000 kilometers.

Therefore, if you buy a second-hand quasi-new car in the second-hand car market, it is like welcoming a new life to your home.

When buying a car, ask a third-party testing agency, or a knowledgeable friend to do a second-hand car inspection and identify the condition of the car.

The next car maintenance generally does not change the suspension rubber sleeve of the chassis, does not need to change the timing belt, and does not need to clean the throttle, fuel injector, air intake, and engine interior.

If you buy a second-hand quasi-new car to do maintenance and maintenance, the auto mechanic has changed the oil and oil filter, and it is recommended to do an engine cleaning package, then don't think about it, he 100% wants to cheat people.

The good-tempered car owner can ignore him and leave directly, and then add the store to the blacklist, and don't have to come back in the future.

A bad-tempered car owner can pick up the largest wrench and point it at his nose first, and then point to his car, and tell him that the labor and management are two years old.

The above is a normal model that does not need to worry too much, according to the time and cycle recommended by the maintenance manual of the car, and the maintenance and maintenance items are also very simple.

Of course, there are also some abnormal models, such as Golf GTI, Focus RS, Toyota 86 and other performance cars.

Such as Prado, Wrangler, Jimny and so on.

Because models like the Golf GTI, Focus RS, and Toyota 86 are bought to play, otherwise who would spend hundreds of thousands to buy it?

Isn't it fragrant to buy an Audi A4L, Toyota Camry, Volvo V40 with more space, more comfort and higher configuration for the same price?

Since it's play, those new car buyers won't cherish it after they buy it.

I can't wait to see who to see every day, I can't wait to start every time I go out to buy groceries, and it's not crow's feet that are bounced, bounced, bounced, and bounced away, and it may be the clutch plate that burns, and the gearbox that is destroyed may be the engine.

Therefore, for the sake of your own safety and wallet, you should pay attention to second-hand performance cars such as Golf GTI, Focus RS, Toyota 86, etc., even if it is a few years old, you must be careful, pay attention to key parts such as clutch plates when maintaining and maintaining, and change what should be replaced, don't try to save trouble, or try to save money. ，

Off-road models such as Prado, Wrangler, Jimny and so on are equally open-minded.

Rushing to the sky, blazing the sand, drilling the jungle, passing the shell crater, the original owners are open-minded, and they sell the car when they are tired of playing, but the pit suffers the second-hand car buyers.

Therefore, you should be careful when you see these models, even if they are several years old, and focus on checking the oil pan, shock barrel, engine, etc. when maintaining and maintaining.

Finally, there is the battery.

Some original batteries are easy to lose power, and a quasi-new car with a year or two years of age will not catch fire if it is not opened for a week, which is a natural tire problem.

When maintaining and maintaining, check it with a battery detector to see how much the battery is attenuated, anyway, the price of the battery is not expensive, about 400 can buy a very good, if not, we will change, and we can't often find someone to take the electricity.

The second stage is when you reach the youth of your life, and you also start to drink, smoke and socialize.

When you are young and middle-aged, it is the peak of the car, and the manufacturer's warranty is often invalid, but at this time, the buckle of the interior plastic parts has fallen off, the cracked has been cracked, and the deformed has been deformed.

Especially in the central control area, some models must be changed if they want to change a set, otherwise they can only endure it and listen to symphony music in the car every day.

The shock absorber rubber sleeve, rusted parts, tires, timing belts, etc. of the chassis should also be paid attention to at this time, especially those owners who often run at high speeds, and special attention should be paid to maintenance and maintenance.

In addition, some models have begun to have signs of engine carbon deposits, oil burning, oil leakage, and transmission oil leakage, which may have just begun, but always be careful.

The third stage is the most important stage of entering old age, what diabetes, what high blood pressure, what hemiplegia begins to appear.

At this stage, the overall performance of the car has declined seriously, all kinds of common problems, problems have broken out in an all-round way, the car condition is in an unstable state, and it is necessary to be careful when maintaining and maintaining it.

The first is the problem of burning engine oil.

German cars, French cars, and even some Volvo, Toyota, Lexus, and domestic cars have the problem of burning engine oil.

Old age and decay, it is normal to burn engine oil and leak engine oil, second-hand cars at this stage do not burn engine oil and do not leak oil, the engine compartment is spotless, new and no friends, there is no need to doubt, there is a problem 100%.

The second is the fuel system and lubrication system of the engine, which needs to clean the oil circuit and fuel tank, because the fuel normally used is made by refining crude oil, and in order to facilitate combustion to improve the quality of the fuel, so that the fuel can be stored for a longer time, some additives are usually added, and these additives will gel and condense after a period of time, and after a certain degree of accumulation, they will be attached to the oil circuit and the fuel tank part.

This deposition will affect the delivery of fuel and even the normal operation of the fuel injection system, and the deposition of the fuel tank will accelerate the deterioration of the fuel.

In order to avoid recurrence of problems after cleaning, and to maintain a healthy state, a higher grade of oil and fuel additives can be used, which can improve the combustion of fuel in the combustion chamber and reduce the pressure of abnormal fuel combustion on the engine block.

The third is to maintain the gearbox, replace the clutch plates, timing chains, etc.

Although most brands now claim that their gearboxes and timing chains can be maintenance-free for life, it is best to maintain them at this stage, even the humble timing chain may cause the top cylinder, and eventually the engine needs to be overhauled.

Secondly, there is four-wheel alignment, replacement of shock absorbers, replacement of suspension pads, control panels, fuses, etc., which need to be checked when maintaining them.

The fourth stage is to the real twilight years, the performance of the car has declined seriously, for the sake of their own safety, in addition to practicing and buying a car to change, can not touch such a second-hand car or do not touch, do not buy, and there is no need to maintain it.

......

In front, Huzi and a few partners were busy, and Fang Yuan walked over.

Fang Yuan had heard Liu Liang say that Zhao Dezhi's Sanxin auto repair factory was similar to Lao Wang's auto repair factory, and they were mainly engaged in second-hand car maintenance and maintenance business in the name of auto repair shop, and at the same time repaired some minor faults or something.

As for overhauling the engine, changing the clutch plate, changing the convertible lifter and the like, I'm sorry, it's the work of a professional and regular auto repair shop or 4S shop, and they can't do it all.

Huzi was standing under the lift at this time to change the oil of an old BMW.

Fang Yuan happened to have never seen it, so he stood aside curiously and watched.

Don't look at Huzi's youth, he works very neatly, and after quickly loosening the oil pan screw to a certain extent with a wrench, he immediately changed to holding the top of the oil pan screw with his hand, and then quickly pulled it out, and the dark engine oil flowed down.

But when the oil was cleaned, when Huzi wanted to reinstall the oil pan screws, he turned around and looked for a long time, but he forgot where to put the screws.

Huzi really couldn't find it, so he simply found a similar style and wanted to install it.

"Huzi, you are slow. Fang Yuan's eyes widened in surprise and asked Huzi, "Don't you know that the oil pan screws of this BMW are made of aluminum?

"Aluminum, as long as it can be installed, isn't it?" Hu Zi was puzzled by Fang Yuan, a pair of big eyes flickered at Fang Yuan, and he hadn't figured out what was wrong.

"Okay, you pretend, I'll see if you can put it on. ”
