Generally speaking, most parts of a car are not easily damaged. The three main parts can be said to be the most stable parts, so the possibility of damage is very small. Some friends' problems are just serious thoughts, not to mention consumables and wearing parts such as filters, brake pads and wipers, because they are often replaced.
Strictly speaking, the damage of auto parts is often caused by external conditions! Automobile parts, such as automobile tires, automobile batteries, automobile wiper strips, automobile rearview mirrors, etc., are easily damaged. If cars often run on paved roads, the tires of cars wear less and are not easy to be punctured. If cars often run on unpaved roads, car tires are easy to wear, and if they are hit by hard objects, they will be damaged and burst, thus shortening the service life of car tires. However, if the car is parked for a long time, the car tires are also prone to aging, cracking and damage, so the car tires are the most vulnerable parts.
Car batteries are also easily damaged. If you often drive to charge the car battery, the battery is also easy to be damaged. After the car enters the working state, the chassis part begins to participate in the work in an all-round way, and the clutch plate, suspension, damping system, automobile tires and other components move smoothly with the car. There is a good relationship between automobile tires and tire pressure in use. If you don't pay attention, it is also very fragile. For drum brake, brake shoe friction plate and brake drum are a pair of friction pairs, which are easy to be damaged.
For disc brakes, the brake disc and caliper are a pair of friction pairs, which are easy to be damaged. In addition, the ball heads and bowls that can be seen everywhere are also easily damaged. Water pipes, water inlets, water tanks and heating water tanks are mainly affected by the quality of antifreeze.
If highly corrosive antifreeze is used, or the antifreeze is not replaced for many years, these parts will corrode and leak. In daily maintenance, it is often found that the antifreeze is not replaced for many years, or water is added to the antifreeze, which leads to the blockage of the water tank and the corrosion and leakage of the water tank or heater water tank. For the manual gearbox, as long as it runs normally and uses the correct gear oil, the probability of damage is very small. Among the three most common automatic transmissions in daily life, AT is the most durable, with the strongest overload resistance and little possibility of damage in normal use. CVT transmission is mainly afraid of overload and heavy driving, and steel belt transmission is easy to be damaged.
Power shifting is mainly for fear of crawling in congested road conditions, which may easily lead to overheating and clutch burning. Moreover, the gearbox is afraid of high temperature, so the heat dissipation of gearbox is also very important. Spark plug is one of the key components of automobile ignition system, and the ignition system is the key point of engine work, so the performance of spark plug is related to the performance and efficiency of vehicle. If it is found that the car is difficult to start in the morning, driving has obvious frustration, idling vibration or engine acceleration performance declines, check whether it is necessary to replace the spark plug in time. The timing belt is responsible for the precise coordination of all key components of the engine. Once the timing belt is damaged, the valve and ignition will close or fail, the engine will not run, and even the cylinder head will be damaged.
There are many other parts that will fail, but there are many reasons for replacement. It is difficult to determine which ones need to be replaced because of scratches, and many others need to be replaced because of normal wear and tear. Spark plugs, various engines, timing belts, batteries, various sensors and electronic parts, door locks, window regulators, etc. Is completely different.
