These few automobile parts are most vulnerable to damage to old drivers and do not know

The number of large and small parts of the car is numerous. In normal maintenance and use, some parts will be replaced and maintained after a while, and some parts will not be replaced until the car is scrapped. Let's take a look at the most vulnerable parts of a car.

1, "Three filters"

Three filters are long-term industry-specific synonymous with three types of accessories: oil filters, fuel filters, air filters. They filter the media in the lubrication system, combustion system, and engine intake system, respectively. Parts that are collected as impurities are often covered with dirt and impurities after being used for a period of time. Once the impurities are too much, the original filtering effect will be lost, the oil will reduce the oil, the engine will inhale the dust, and the fuel consumption will increase. A series of problems such as reduction came one after another.

2, spark plug

1. The spark plug is used to ignite the cylinder of the gasoline engine. The operation process of the engine is very critical. It can be said to be the heart of the engine. We all know that the cylinder is a very harsh environment. Under the long-term training, the spark plug will appear. Various problems, such as excessive carbon deposition, overheated combustion, and external damage, etc., should be checked when the car is found to be unstable at idle, power is weakened, startup is difficult, or it is turned off without reason.

3、 Timing belt

The timing belt is an important part of the engine's air distribution system. By matching the crankshaft to a certain transmission ratio to ensure the accuracy of the intake and exhaust timing, due to the rubber products, it is obvious that no metal is so durable. Once the timing belt is damaged, Valve and ignition work will be indiscriminate or even stop, the engine will not work properly, and the cylinder head will be seriously damaged. If this happens, the engine will need to be overhauled.

4、 Wiper

The wiper is a rubber product. It will show signs of ageing and cracking in the long-term wind, rain, rain, and sun. If you find that the wiper's motion is not smooth during normal use, you can still hear the rubbing noise from the glass. It may be The windshield wiper is excessively pressed against the glass. At this time, the wiper should be properly adjusted. If the phenomenon of loosening and cracking occurs, the wiper must be replaced.

5, brake pads

The braking effect largely depends on the brake pads and the tires. In long-term use, the brake pads will become thinner due to wear. In normal maintenance, the brake pads should also be inspected to see if they need to be replaced. Generally, the car has brakes. The alarm film, when worn to a certain degree, the vehicle will emit a harsh metal friction sound to remind the driver, in this case you must replace the brake pads.

6, tires

Don't look at the size of the tires. In the usual driving, the area of ​​contact with the ground is only four palms. Imagine that there are now more than one ton of vehicles and the pressure on the tire contact surface is very large. While keeping the ground in place, the impact from the road surface must be relieved and vibrations must be reduced. If the car is often uneven, it is more likely to damage the tire cord by walking the gravel road and stepping on the road. In the usual daily inspection, more attention should be paid to the condition of the tire, such as whether it is worn to the extreme position, and problems such as bulging and splitting occur. In addition, although it is possible to repair the tire, it is safer to replace the tire with a new one after a few times.

7, battery

The battery is the energy source of the electrical function in the car, and it is the most critical part of the car's electrical system. Many accessories on the car rely on the battery to play its role, such as air conditioning, audio, etc. In the automatic transmission, if the battery is damaged, Will make the car can not start. The service life of the battery is not only limited by its own quality, but also related to the user's habits and whether it is properly maintained. In normal use, the terminal of the battery should be regularly checked for dirt, and the clamp is damaged. Before the vehicle stalls, Make sure all electrical equipment is turned off.
