Car maintenance and repair _ the most easily overlooked aspects

In the car maintenance and repair, the owners have their own car maintenance habits, generally replace the oil, three filters and other consumables, and then often car wash and wax. In fact, this is the most basic car maintenance, the car has a lot of fragile parts, if not often checked, repaired and maintained. It may be a pain to break down on the road. The following small series introduces you to the most overlooked places in car maintenance~



1. Steering rod deformation

When the vehicle is parked, if the steering wheel does not return to the right direction, the wheel will be unable to return to the steering lever, and the gears of the steering wheel and the rack of the steering rod are also under stress. Over time, these parts will accelerate aging or deformation. When cleaning, be sure to check this part carefully. The procedure is simple: hold the lever and shake it vigorously. If it is not shaking, it means everything is normal. Otherwise, the ball or lever assembly should be replaced.

2. Ignition line aging affects performance

Most car owners have already realized that the ignition line is a problem when the car has insufficient energy, high fuel consumption, low power and even fire. When the engine is running, there are often tens of thousands of volts of high-voltage pulse current on the ignition wire. Because it works in a high-temperature, dusty, and vibrating environment for a long time, it is inevitable to be aging or even damaged. The distributor cover, split burner, ignition coil, spark plug and other components in the ignition system should also be within the scope of routine maintenance and inspection. Brake disc wear affects driving safety. The owners have been staring at the brake shoes. They rarely pay attention to the brake disc. After a long time, it will directly affect the safety of the brakes. If the brake disc has clear scratches, it is recommended to replace it with a new one. Generally speaking, after the brake shoe is replaced 2 or 3 times, the brake disc should also be replaced.

3. The exhaust pipe rust sound becomes louder

The car has a large loss of power due to rust and corrosion of the exhaust pipe, which is mainly caused by lack of maintenance. If the exhaust pipe has a discoloration of the muffler, and when the exhaust pipe enters the water while driving on a deep water surface, and then the engine is turned off, the damage is fatal to the car. Therefore, the exhaust pipe is one of the most vulnerable parts of the vehicle bottom. Don't forget to take a look during the inspection, especially the exhaust pipe with three-way catalytic converter, which should be carefully checked. It is recommended that the new car be maintained once after the card is put on, and it should be maintained once every six months.

4. The generator bearing is insufficiently lubricated

Automobile generators are an important part of automotive electronics. Its function is two parts: the need to supply each part of electricity; the battery is charged. In order to maintain the constant power generation state of the generator while driving, it is necessary to adjust the tightness of the generator belt properly, and then fix the calibration screw as needed. Also pay attention to the degree of wear of the bearing. If it is found that the lubrication is insufficient, it can be taken from the oil cup mouth. Drip the oil. Generally, the generator is inspected once after the car has traveled 6 to 80,000 km.

5. Shock absorber affects driving stability

The shock absorber is a fragile accessory during the use of the car. The shock absorber works well and will directly affect the stability of the car and the life of other parts. When the car is driving slowly and braking urgently, if the car vibration is severe, it indicates that the shock absorber has a problem. Of course, due to the influence of different factors such as load capacity, use time, road conditions and driving methods, the shock absorbers will also be attenuated to varying degrees.

6. Wiper repair improperly reduce life

If you drive in heavy rain, the unclear sight is a hidden danger, and the importance of the wiper is revealed. If the wiper does not wash the rain well, it will pose a great danger to driving safety. Since the material of the wiper blade is mainly rubber, it will age and harden for a long time. The owner can buy a rubber curing agent from the auto supply store, and spray the rubber part of the wiper blade every month to at least extend the rubber strip 30-50. % of service life. If the blade ages, hardens or cracks, it should be replaced in time. The work of replacing the blades is not complicated and can be done by yourself.

7. Dial warning light is badly harmful

Everyone saw a warning light on the dial, but most people continued to drive without taking any action. According to a data set published by CarMD, 64% of drivers admitted that they had at least one overdue experience, and more than half of the drivers had continued driving for more than three months with the warning light on. The warning lights on the instrument panel will illuminate mostly because of spark plugs or spark plug wires, and the maintenance cost is not high.

The instrument panel should also be cleaned and cleaned according to different places. To improve the brightness of the instrument panel, after cleaning, add a few drops of walnut oil or olive oil to the rag and polish the parts.

I have seen so much knowledge about car maintenance, and these are the most overlooked places. Car owners must remember to check and maintain the car frequently, so that you will not have a fault when driving, which will bring convenience to your driving journey.
