Truck maintenance knowledge

1. First service is critical

The maintenance of new cars should be done enough. Most car owners will go to a special service station for maintenance according to the manufacturer's regulations when they reach the first warranty period, because most car manufacturers offer a free oil change for new cars during the first warranty period. For example, Shanghai GM will provide four free oil and oil filter replacement services during the warranty period. However, there are also a few car owners who neither consult the staff nor read the maintenance manual, so there are also examples of missing the first service. As it is a new car, the owner missed the first service, but the engine oil is only getting darker and dirtier, which will not cause any serious consequences. However, experts suggest that car owners should do the first service, because the new car is in running in state, and the running in of mechanical parts will have a high demand for lubricating oil. This is the significance of doing the first service.

2. Second insurance is also important

Relatively speaking, the second maintenance is very important to replace the brake pads after 40000-60000 kilometers. The project involves the inspection and maintenance of up to 63 items in eight major parts, including engine, automatic transmission, air conditioning system, steering system, braking system, suspension system, body part and tire. In addition, it also includes quality inspection and commissioning. It can be seen that after so many tests and maintenance, the whole vehicle condition will obviously enter the best state, and the driving safety can be best guaranteed.

3. Key maintenance items

(1) Brake pad

Generally speaking, the brake pads need to be replaced when the vehicle reaches 40000-60000 km. For owners with poor driving habits, the replacement journey will be shortened accordingly. If the owner sees the red light ahead, refuels instead of receiving fuel, and then takes the drag brake method to wait for the green light to pass, this is such a habit. In addition, if the main vehicle is not maintained, it is impossible to find that the brake skin is thin or completely worn in time. If the worn brake skin is not replaced in time, the braking force of the vehicle will gradually decline, threatening the safety of the owner. In addition, the brake disc will also be worn out, and the maintenance cost of the owner will increase correspondingly. Take Buick as an example. If the brake skin is replaced, the cost will only be 563 yuan. However, if the brake disc is damaged, the overall cost will reach 1081 yuan.

(2) Tire transposition

Note that one of the tire maintenance items of the second warranty for tire wear marks is tire transposition. When using a spare tire in an emergency, the owner should replace it with a standard tire as soon as possible. Because of the particularity of the spare tire, Buick does not adopt the method of circular transposition between the spare tire and the tire of other models, but four tires are transposed diagonally. The purpose is to make the tire wear more evenly and prolong its service life. In addition, tire maintenance items also include adjusting the air pressure. The owner of the vehicle cannot despise the tire pressure. If the tire pressure is too high, the middle part of the tread will be easily worn. It is worth reminding that if the tire pressure is measured without the help of a barometer, it is difficult for the car owner to visually measure it accurately. There are still some details about the daily use of tyres. If attention is paid to the distance between the tread and the wear mark, generally speaking, a new tire should be replaced if the distance is within 2-3mm. For another example, if the tire is punctured, if it is on the sidewall, the owner must not listen to the suggestions of the Express repair shop to repair the tire, but should change the tire immediately, otherwise the consequences will be very serious. Because the sidewall is very thin, it will not be able to bear the pressure of vehicle weight after repair, and it is easy to have a flat tire.

Put prevention first, combine prevention and treatment, and carry out standard maintenance according to the maintenance manual. So the truck won't have big problems.
