Detailed explanation of the life of auto parts
The service life of auto parts brake pads is usually determined by the owner's personal braking frequency and road conditions. Generally speaking, brake pads need to be replaced when they have traveled about 50,000-80,000 kilometers, and if the wear degree is calculated, it is limited to one-third.
The following are some special situations that need attention:
1. Novices usually step on the brakes more, and the consumption will be greater.
2. Automatic transmission consumes more brake pads than manual transmission, because the gear shift of automatic transmission depends on the accelerator pedal and the brake pedal.
3. For cars that often drive in the city, the brake pads will wear out faster than those that often drive on the road. Because cars that often drive in the city often have to stop and go, they will use the brakes more. On the road, you may need to slow down or stop after driving for dozens of kilometers, and the opportunity to use the brakes is relatively rare.
4. Cars with heavy loads have large brake pads. Under the same speed, the inertia of heavy cars is large, and the friction force required for the brake pads is large, so the wear is large.
Generally speaking, in mixed driving conditions (half highway, half urban), the front brake pads should be able to be used for 60,000-70,000 kilometers. The rear brake pads should be able to be used for more than 100,000 kilometers. Of course, this is not absolute, but just an average estimate. The front brake pads wear out faster because when braking, the center of gravity of the car will lean forward, and the front brakes have to bear more force than the rear brakes.
Therefore, the disc and pads of the front brakes are generally larger than those of the rear brakes. After you change the brake pads, the braking effect will definitely not be as good as before, and the brakes will feel softer. At this time, you must step on the brakes several times to eliminate the gap between the pads and the brake disc. In addition, it takes 200 kilometers to run in to achieve the best braking effect. The newly replaced brake pads must be driven carefully, and be careful not to follow the car too closely. Top Ten Brake Fluid.
Its service life is 60,000 kilometers or 3 years. It is worth mentioning that the brake fluid should be replaced on time, otherwise, air blockage will occur due to deterioration, resulting in brake failure.
The general brake fluid replacement cycle is three years. Brake fluid has been used for a long time, and although it does not have much effect on the surface, problems are likely to occur when the vehicle is in emergency braking or driving downhill for a long time. The brake system will cause the brake fluid temperature to rise rapidly during long-term or emergency braking. Brake fluid itself has a strong water absorption property. It will absorb moisture from the surrounding air. For example, when washing a car or in humid air, moisture will penetrate into it. The accumulated moisture entering the brake fluid will directly cause the boiling point of the brake fluid to drop, and the braking force will decrease accordingly. At the same time, it will cause air resistance in the brake line, thereby affecting the performance of the brake. In addition, moisture will corrode the brake line, causing damage to the internal valve of the anti-lock brake (ABS) hydraulic assembly, seriously affecting the transmission response of the brake. Furthermore, the use of brake fluid for a long time will also cause the leather cup and piston in the brake pump to wear, causing the brake fluid to become turbid.
The quality of brake fluid is very important. Pay more attention when choosing brake fluid. If it is unqualified or of average quality, it will corrode the leather plug of the brake pump and affect the braking effect.
Auto Parts Air Filter
Some people say that it should be replaced every 15,000 kilometers, or every 20,000 kilometers, or every 30,000 kilometers, 50,000 kilometers, and so on. There are different opinions, and there is actually no conclusion. As mentioned earlier, the replacement of the filter has a lot to do with the environment, and it depends on the amount of dust and sand inhaled by the air filter, because it depends on the amount of dust and impurities inhaled by the air filter. To make a simple analogy, if the same car has been driving between cities, it may not matter if it is replaced every two or three years, compared to traveling through rural and mountainous areas with high dust concentrations, because the dust content in the air is relatively low compared to mountainous areas. Therefore, there is no absolute standard for the replacement of air filters. If it refers to cars, there is no conclusion. All you have to do is to pay more attention to the air filter during routine inspection and maintenance to see if the interior is clean or if there is dust accumulation. If the interior is very dirty, it must be cleaned or replaced.
Auto Parts Air Conditioning Filter
Manufacturers generally stipulate that it should be replaced every 20,000 to 30,000 kilometers. However, in actual use, it usually needs to be replaced after 10,000-20,000 years. Because it is usually cleaned with high-pressure air during maintenance, and try not to use external circulation during general use, because there is too much dust on the road. When the car is driving with the air conditioner on, it needs to inhale external air into the car, but the air contains many different particles, such as dust, pollen, soot, grinding air conditioner filter particles, ozone, odor, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. If there is no air conditioner filter to filter, once these particles enter the car, not only will the car air conditioner be polluted and the cooling system performance will be reduced, but also the human body will have allergic reactions after inhaling dust and harmful gases, damage the lungs, and be irritable due to ozone stimulation, and the influence of odor will affect driving safety. High-quality air filters can absorb dust particles, relieve respiratory pain, reduce irritation to allergic people, make driving more comfortable, and protect the air conditioning cooling system.
Please note that there are two types of air conditioning filters: one is without activated carbon, and the other is with activated carbon (please consult before purchasing). The air conditioning filter containing activated carbon not only has the above functions, but also absorbs a lot of odors.
Auto Parts Fuel Filter
We know that gasoline is refined from crude oil through a complex process, and then transported to various gas stations through a special channel, and finally delivered to the owner's fuel tank. In this process, impurities in gasoline will inevitably enter the fuel tank. In addition, as the use time increases, impurities will also increase. In this way, the filter used to filter the fuel will become dirty and full of residues. If this continues, the filtering effect will be greatly reduced. Therefore, it is recommended to replace it when the mileage is reached. If it is not replaced or delayed, it will definitely affect the performance of the car, resulting in poor oil flow, poor fueling of the car, and finally leading to chronic damage to the engine, or even overhaul of the engine. This cost can be equivalent to the price of many fuel filters.
Auto Parts Oil Filter
It is consistent with the life of the engine oil, and it should be replaced when the engine oil is changed. First of all, what car did you buy? The maintenance cycle of various household cars is different. Generally, the oil change is within the range of 5,000 to 10,000 kilometers, or according to the time and mileage specified in the maintenance manual.
Battery
Currently, many vehicles use maintenance-free batteries, and its service life is theoretically 2 years. Water-added batteries can reach 3 years. There is a prerequisite for the 3-year life of water-added batteries, that is, to keep the battery water within the standard range. If there is a lack of water, the life will be shortened. If maintenance-free batteries and water-added batteries are charged with a special charger every 5,000 kilometers, the service life can be extended by 50%. When driving at night, once the neutral gear is engaged or the lights dim at idling, it indicates that the battery is about to be replaced. However, the service life of some batteries currently does not reach the theoretical service life, depending on different models.
The service life of ordinary spark plugs is 30,000 kilometers, platinum type is 50,000 kilometers, and iridium type is 70,000 kilometers.
Car maintenance is very troublesome. When the car travels to a certain number of kilometers, the spark plug will produce carbon deposits and the electrode gap will increase. Carbon deposits will increase the engine fuel consumption, and the increase in the spark plug gap will cause difficulty in starting. Therefore, regular inspection and maintenance of spark plugs can extend the life of the engine.
To achieve maintenance, first of all, the air filter should be cleaned regularly to prevent dust from entering the combustion with the mixture, so as to prevent the spark plug from being corroded. Secondly, you can also remove the spark plug by yourself and clean the dirt and carbon deposits on the ignition head. However, it is particularly important to note that when disassembling and assembling the spark plug, be careful not to let dust enter the cylinder when the spark plug is in and out, and the surrounding area should be cleaned in advance when the spark plug is disassembled. If there is oil in the cylinder, the piston ring or other parts should be replaced in time to prevent carbon deposits on the spark plug from causing electrode short circuit. In addition, the quality of fuel is also closely related to the life of the spark plug, so you must pay attention when refueling. You should not add fuel with quality problems just to save money, otherwise you will regret it.
Timing belt
If the car manual does not make clear instructions, the replacement cycle of the timing belt is usually 60,000-80,000 kilometers. If the timing belt is disconnected due to failure to replace it in time, the car will automatically shut down. At this time, if the driver continues to ignite, the valve tappet will bend, greatly increasing the maintenance cost.
