Don’t just change the engine oil when maintaining your car. These 6 places are also very important. Many people may not know it

• Raising a car is like “raising a child”. Buying a car in the early stage is a “one-time expenditure”, but maintaining a car in the later stage is a “continuous expenditure”. As long as the car is still in your hand for one day, you must take good care of it.

• Many car owners know that they should maintain their cars regularly, but every time they go for maintenance, they only know how to change the engine oil and clean them. Not long after the maintenance, they find that their cars frequently break down, but they don’t know what went wrong.

• When doing car maintenance, there are several places that must be checked and maintained. Many people may not know it. Whether it is a novice driver or an experienced driver, it is recommended to collect them and learn about them.

Don’t just change the engine oil when maintaining your car. These 6 places are also very important. Many people may not know it

1. Car shock absorber

The suspension system of a car is basically equipped with Shock absorber, which can quickly attenuate the vibration of the frame and body, and improve the ride comfort and comfort of the vehicle when driving. The most common problem with shock absorbers is oil leakage. Once it starts to leak oil, the stability and comfort of the vehicle will be affected, and the vehicle will shake obviously when passing through bumpy roads. Over time, the braking distance of vehicles will become longer, thus affecting driving safety.

However, many car owners don’t understand this problem at all. Even some drivers who have been driving for five or six years have never paid attention to their shock absorbers. When maintaining the vehicle, remember to check the chassis and shock absorption system of the vehicle, and repair any problems in time.

2. Hub bearing

This is also a very important part of the car. Its main function is to bear load and provide accurate guidance for the rotation of the hub , routine maintenance is also essential. Once the hub bearing fails, it will cause problems such as noise and bearing heating.

When the wheel hub bearing fails, the vehicle will have obvious performance: During driving, the vehicle will make an abnormal buzzing noise. The bearing is seriously damaged, and the car body will shake during driving, and the power will be erratic. If your vehicle is experiencing these problems, go and check the bearings promptly.

3. Brake disc

The brake disc is like a circular plate, and it will rotate with the car as it moves. When we step on the brakes, the brake calipers will clamp the brake disc to slow down or stop.

Brake discs need to be replaced regularly, generally once every 70,000 kilometers 。 Of course, this is not an absolute value. If you usually drive violently and often slam on the brakes, the wear of the brake disc may be serious, so you should replace it in advance.

After all, the braking system affects the whole driving safety, so it is necessary to check the brake disc regularly. If you don’t know whether the brake disc should be replaced, you can ask the maintenance master to take a look at it for yourself when you go for maintenance.

4. Spark plug

Car owners are very concerned about the engine, but it is easy to ignore the spark plug. Although the engine is important, the spark plug is equally important, because if there is a serious problem with the spark plug, it means that the engine may not die soon, so the spark plug is very important.

What we know is that the service life of the spark plug is different. Sometimes it is longer, and the car may have run 100,000 kilometers before it needs to be replaced, while sometimes the spark plug will no longer work at 30,000 kilometers. Therefore, car owners can’t generalize that the service life of the spark plug is very long, or they should check whether it needs to be replaced with a new one when maintaining the car.

5. Air conditioning evaporation box

Car air conditioners are used frequently. Many cars have only been driven for two or three years, and the air conditioning effect becomes worse, and the odor is particularly serious. Even if the air conditioning filter element is replaced, it has no effect. That’s because, The real odor source is in the evaporation box.

The evaporation box of automobile air-conditioning has been in a dark and humid environment for a long time, where dust stops and bacteria breed, which is the dirtiest place in the whole air-conditioning system.

In addition, not cleaning the evaporator box for a long time will also increase the fuel consumption of the vehicle.

6. Three-way catalytic converter maintenance

The three-way catalytic converter is the most important part in the exhaust pipe. The three-way catalytic converter is made of rare metals, so the price of the three-way catalytic converter is very expensive. It costs as little as 3,000 yuan to replace a three-way catalytic converter as much as five or six thousand yuan.

You know, once the three-way catalytic converter is clogged, Will cause The car is very weak when accelerating, and the rotation speed of the engine will also slow down. Increasing the speed of the car will become the biggest difficulty. If you want to speed faster, you must step on the accelerator hard, which will shorten the life of the three-way catalytic converter. Exhaust gas exceeds the standard and even leads to the interior of the car Carbon deposits More and more, the fuel consumption is rising sharply, which may even lead to spontaneous combustion of the car. Therefore, we should pay attention to the cleaning of the three-way catalytic converter at ordinary times.

Want to thoroughly clean up the carbon deposits in the three-way catalytic converter , you can use a safe and effective carbon deposit cleaner, which is also a method used by many veteran drivers at present. Not only is the cleaning effect good, but the cost is not high. If your car also needs to clean carbon deposits, you can use the following veteran The product is being used by all drivers. It has a good effect on removing carbon deposits and high safety performance. It is worth recommending and praised by everyone who has used it!
