Easy to replace car wearing parts yourself

As the name implies, "consumable parts" are the parts that are most easily damaged and replaced in automotive parts. So, what are the wearing parts of the car? How long is the replacement cycle of different wearing parts? How to extend the life of these wearing parts? On these issues, the reporter interviewed Xiao Nan, the manager of the service department of Changan Mazda Junxiong specialty store.

Wiper Blade

For the wiper blade replacement, Xiao Nan said there is no fixed period. However, according to the weather conditions in Xi’an, wiper blades should be replaced once a year. When using a wiper blade every day, it is necessary to avoid “dry scratching”, which can easily damage the wiper blade, causing serious damage to the glass of the vehicle. It is best for the owner to start the wiper after spraying the glass with better cleanliness and lubricity. At the same time, the car washer should also clean the wiper at the same time.

Mr. Sun, who is engaged in sales of auto parts, suggested that when replacing the wiper blade, the owner should refer to the vehicle's instruction manual to purchase a suitable size wiper. “When choosing a wiper blade, the owner can touch the rubber wiper surface with his fingers. If the blade is found to be aging, hardened, cracked, and the rubber blade is not flexible, it can be determined as a shoddy product,” Mr. Sun said.

Brake pads

According to the individual's driving habits, the service life of the brake pads is also different. Xiao Nan said that in daily maintenance, it was discovered that the brake pads of some vehicles need to be replaced after driving more than 10,000 kilometers, while some vehicles can still work normally when they are driving around 80,000 kilometers. "Brake pads that can still be used normally for around 80,000 kilometers are examples." Xiao Nan explained that the owner should check the brake pads of the vehicle when it is about 20,000 kilometers. Normally, replace the brake pads around 30,000 kilometers. . Usually, the owner can check the brake pads by touching the tire's sidewall with his hands after parking. If the temperature of a tire's sidewall is particularly high, it is likely that there is a problem with the brake pads. The owner should immediately go to the 4S shop to perform brake pads. an examination.

Tires

“Under normal conditions, the replacement cycle of a tire is 30,000 to 40,000 kilometers. When a car 4S shop does chassis maintenance after driving 10,000 kilometers, it will convert the four tires of the car accordingly, thereby prolonging the use of the tire. Life.” Xiao Nan said that after the vehicle is traveling 20,000 kilometers, the owner is better to do a four-wheel alignment, correct four rounds of data, to ensure the normal use of tires, to prevent eccentric wear. If the four-wheel alignment data is inaccurate, it is easy to cause uneven wear of tires and reduce tire life. "When the tread pattern is less than 1 mm, the owner must replace it immediately!" Xiao Nan emphasized.

Spark plug, engine timing belt, battery

Xiao Nan said that spark plugs can be divided into platinum spark plugs and ordinary spark plugs in two categories, platinum spark plugs are generally in the 80,000 to 100,000 km exchange, and ordinary spark plugs are much shorter life expectancy, usually 20,000 to 30,000 kilometers need to replace. The life of the spark plug is also related to the quality of the fuel. Therefore, when the owner is refueling, it is best to go to a regular gas station.

The engine timing belt is preferably checked or replaced at 2 or 60,000 kilometers. However, if the vehicle is equipped with a timing chain, it does not have to be replaced by the "2 or 60,000 kilometers" constraint.

The battery is usually checked and replaced as necessary after 2 years. Xiao Nan reminded that at ordinary times when the vehicle is off, the vehicle owner uses as little as possible the vehicle's electrical equipment to prevent the battery from losing power.

Three filters

The riders used to refer to oil filters, air filters, and fuel filters collectively as "three filters". Since they play a role in filtration, they need to be replaced in time. Normally, the oil filter is replaced every 5,000 km of oil; the air filter is replaced about 20,000 km. If the vehicle is used in areas where the air pollution is serious, it needs to be replaced in advance; the fuel filter is usually also Replaced at 20,000 kilometers.

Vehicle oil

For the various fluids required for the vehicle to work, Xiao Nan said that according to the vehicle usage, the engine oil is usually replaced at 5,000 km or 3 months, and the engine oil should be checked regularly to ensure that it is above the bottom line; brake oil is It is recommended to change it when it is about 40,000 kilometers; antifreeze is generally replaced in 2 years or 60,000 kilometers, and always pay attention to the observation of the liquid level. If it is lower than the lower limit, it must be replenished in time; transmission oil is between 50,000 and 60,000. Replaced when in kilometers; steering oil is replaced at 60,000 kilometers.
