In addition to normal minor maintenance items such as three oil filters, whether it is a 4s shop or a repair shop, spark plugs will be inspected and replaced, because spark plugs also have a life, and spark plugs that have been used for a long time will experience aging and carbon deposition. As the most critical part of the engine, if not replaced in time, blind use will not only lead to increased fuel consumption, but also seriously lead to the lack of cylinders or failure of the engine. Therefore, this component must be replaced regularly, and generally no matter where it is replaced, current merchants will trick consumers into replacing the so-called platinum spark plug. The price is very expensive, and many inexperienced car owners will be deceived and spent wrongly. But in fact, you only need to replace the spark plug with the original model, and there is no need to spend more money.

The second is brake maintenance, because after the brakes have been used for a period of time, more or less dust and oil will enter the components of the brake system. These gullies are difficult to wash when we usually wash the car, especially during the use of drum brakes, dust generated by the friction between brake pads and brake discs will accumulate in the brake drum. If it is not cleaned regularly, it will be very harmful. Therefore, as the most important brake for car safety, Regular cleaning and maintenance is still necessary, but an old driver reminded that maintaining brakes does not mean replacing brake pads, and many novice car owners often suffer losses in this place.

The third is the inspection of booster oil, coolant, brake fluid and other auxiliary types. At this time, the main purpose is to check whether the oil is sufficient and whether the color is normal. However, under normal circumstances, these things are far from reaching the limit of use. If you are not necessary, you only need to replace them with the mileage and time indicated in the installation instructions.

Finally, because major maintenance items such as the third and above, the inspection of various connecting parts and tires of the chassis are all manual inspections, it is best for the owner to check on site at this time. After all, it is not uncommon for the items on the inspection list to be typed out, but the car has not been moved at all. It is better to be careful. Overall, a large part of the major maintenance items are important to safety.
