If you drive 100,000 kilometers and don't change trains, which part do you want to replace? According to the maintenance manual there are many things to replace. What's more, the 4S store recommends replacement parts in order to maximize profits, and if they are not replaced, "it may be life-threatening!" In short, don't scare you, I swear not to give up. On this question, we change our minds, and everyone knows the reason: if you run 100,000 kilometers, which part should you change? To say something simple, it's not wrong to subtract from the maintenance manual. For example, when "5 oil 4 filter 3 water" is vulnerable and affects driving safety, it is necessary to check the tires, batteries, brake pads, etc.
Regarding the parts that protect life, I will replace them! The first one: tires! No, it's risking your life! Tires run 100,000 kilometers and stop for a year, which is more harmful? Many people think that tires are worn and wear, and driving less can prolong the use time, but in fact this cognition is not scientific. After running 100,000 kilometers, the tires have also reached the limit of use, and if you are not careful, the tires will burst, and the car may also be destroyed. On the other hand, after a year of stopping, the tires look unbranded and the actual harm is greater. This is because the tire is subjected to a little force for a long time, and the wind and sun will add too much burden to the side of the tire, resulting in long-term rupture and rupture. This is why many cars wear car clothes for a long time and the tires leak.
According to the maintenance manual, the life cycle of the tire is 5 years or 50,000 kilometers. This is the safety red line set by tire companies for tires, people who do not know the car should pay attention, but in reality, many people have not run 50,000 kilometers, but have not changed tires for more than 100,000 kilometers, and people who run 70,000-80,000 kilometers account for the vast majority. From the point of view of cutting costs, one tire running 100,000 kilometers is indeed enough. Driving habits are good, if you only drive on the roads in the city, you can also travel tens of thousands of kilometers. From the perspective of safety, even if the tire is driven to 100,000 kilometers, it can only be said that the owner's heart is very strong and jokes about life. Regarding tires, after more than 5 years or 50,000 kilometers, you can not rush to replace them, but please check the tires before driving, tie the bulge, cracks, cuts or nails before driving. If there is an abnormality, it can be repaired, but if it cannot be repaired, please replace it as soon as possible. If you have reached 100,000 kilometers and have not changed your tires, please replace them. You can save money, but you can't save lives.
The second one: brake pads! No, it's a life-taking car! What are truck drivers most afraid of? It is said that trucks that often run long distances are most afraid of running through the car and are most afraid of driving tired, while truck drivers are most afraid of going down the hill. Brakes are prone to failure. The center of the control brake is the brake pad! My first car was a brake pad that was exchanged for 50,000 km. Some people may say that I am stupid and have a lot of money, but it is actually related to my driving habits. It was just driving, and there was no feeling of throttle or brakes. So, suddenly stepping on the oil, suddenly braking, the signal reading sense of the second has no sense of distance. I thought I could open the throttle, but after passing the light, it suddenly turned into a yellow signal, emergency braking, and said to the car master: "This is the first time to change the brake pads with 50,000 kilometers." Cars don't drive like that."
Some veteran drivers joked that a car was scrapped and had not changed its brake pads. It's really possible. They brake by the driving characteristics of the engine, so to put it bluntly, they start slowly, slowly refuel, and relax the throttle. For ordinary drivers, a car runs 100,000 kilometers, and the brake pads must be checked. This one can be known to the naked eye. In addition, it can also be judged by the sound of brake pads wearing. In short, if the car can't stop, the problem is big. It will suffer losses in the city, but it will suffer losses on the highway. The third: timing chain (timing belt)! No, the engine is waiting to be scrapped! If it is a timing chain, it is generally necessary to maintain, oil is indispensable, and it is generally not broken until it is scrapped. If the timing belt is timed, it must be replaced within 100,000 kilometers. At this point, although it can't be broken for a while, it can barely run 20,000-30,000 kilometers. However, as long as it is broken, only the timing belt will be replaced if it is light. (It's also not expensive.) Heavy weights can damage the cylinders and valves inside the engine. At that time, not only the timing belt should be removed, but also the engine should be removed for repair. That would cost a lot.
It's a syncing car, so please don't give it to me luck. This can be broken. After all, it is a consumable, and if you run tens of thousands of kilometers, it looks cheap and convenient. Once broken, the car went into the nest on its stomach. Even if you stop at high speed, the money known as the trailer fee is enough to replace the timing belt with an abandoned one. Regarding the parts of the warranty car, we will replace it if there is a sign! The fourth one: battery! Can't be contacted when driving, others need money to use electricity! Once I was on a business trip for half a month, and the car was parked in the neighborhood. When I came back to plan to drive, the car didn't move. I don't know if the battery ran out of battery at that time. The initial reaction was to find a 4S store. As a result, I was told that there was no rescue car that day, so I had no choice but to go to a nearby auto repair shop. Long story short, people say that the battery may be out of power, saying that it can be seen. The master lit it to see that the battery was out of power. Then he fixed it with a spare battery, three times five divided by two. How much? He said fifty yuan, and when I was trying to give him money, he asked, "Won't there be no electricity again?"
His battery has been for more than three years, and if he doesn't open it for a long time, he may run out of power. I'm worried that I won't be able to wear it next time, and I'll say how much it will cost to make a new one. He said the battery for this model is $400. Because I said I wanted to change it, he went back to the store and got the new one. In addition, I said that if my old battery was given to him, the 50 yuan could not be charged for electricity. I gave him the old battery. Do you think it's necessary for everyone to replace the battery for three years? Running 100,000 kilometers, ordinary drivers generally drive for at least 5-7 years. If the battery has not been replaced before, this mileage should be careful. It's good to drive if you don't get it right. You can't do it when you come back from eating. In fact, the power loss of the battery is indicative. When you shoot, the car seems to be "exhaling" several times. This is a prelude to battery electrical loss. However, after putting in the new battery, the ignition is enough. Of course, a driver with strong hands can prepare battery cables and backup power in the car. In this case, there is no need to ask others.
The fifth: spark plugs! If you go to the 4S shop, in the overhaul of 30,000 kilometers, he may suggest that you replace it, but there are also car owners who drive 100,000 kilometers without replacing the spark plug, so this problem is not certain. Many car owners do not remember to replace the spark plug, in fact, be careful. When doing large maintenance, it is best to let the master check the spark plug. Is this okay, there will be carbon deposits in it when there is a problem. Generally a cycle of 50,000 km replacement. Sixth: transmission oil! When it comes to oil, people change the oil most often, but many people don't know what the oil of the transmission is used for. I know the task oil, but the mission, but the core of the fuel car, broken is trouble. Now the transmission is divided into AT, CVT, dual clutch, but these mechanical components are inseparable from the lubrication of oil According to the workshop manual, the automatic transmission oil exchange does not exceed 100,000 km CT and the dual clutch does not exceed 60,000 km.
But some of my friends drove more than a hundred thousand kilometers and didn't see their exchange. The point is that there are no problems. The most incredible thing was that my cousin drove a taxi. A car driving 50,000-600,000 kilometers has not changed the transmission oil. Manually operated taxis can only be said to be the board. There has always been controversy about transmission oil, which is based on the condition of the car to determine whether to replace. If there is stuttering in the gear shift, the operation is not so smooth, and the number of kilometers exceeds 100,000, you can consider replacing the transmission oil. Regarding saving money, don't change this casually! All vehicle lubricants! liquid! According to the maintenance manual, lubricating oil, brake oil, coolant should be replaced when it reaches 30,000-50,000 kg!
