Do you really know about the maintenance project of 4S shop?
Automobile oil circuit cleaning
4S stores often recommend removing carbon deposits. Of course, there are many ways to remove carbon deposits, such as cleaning engine oil and removing carbon from intake air. Not many car owners know the technical terms, but listening to the name is a headache. In fact, cleaning up carbon deposits does not need to be so troublesome. Only cleaning the throttle can effectively reduce carbon deposition. Cleaning the throttle is not a high-tech maintenance, and the price is much cheaper than CLEA. Tighten the entire oil pipe.
Air conditioning filter element
According to the introduction of 4S shop, the air-conditioning filter element is replaced twice a year. But in general, it can be changed before summer every year. There is no need to change it twice. If you change the air conditioning filter twice, it is obviously a place lacking money. In addition, the replacement of air conditioning filter element can be completely operated by itself, saving a lot of money.
Air conditioning maintenance package
Air conditioning maintenance is necessary, but it is not fooled by the clerk. Air conditioning maintenance is air conditioning disinfection, ozone disinfection and so on. But in fact these items are just sprayed on the car. Even if you look at it, you don't know what it is. In fact, these things can achieve the same effect by buying a disinfection bottle sprayer and opening an internal circulation, so it is only necessary to change the air conditioning filter element for air conditioning maintenance in the workshop.
Remove carbon deposit
The average family car will produce a certain amount of carbon deposit after driving for a period of time. If there is too much carbon deposit, it needs to be cleaned up. Because there is too much carbon deposit, it will be difficult to strike a fire, idling jitter and high fuel consumption, and the power and performance of the car will be affected to some extent. Under normal circumstances, vehicles traveling 30,000 to 50,000 kilometers need to remove carbon deposits. Be sure to check whether there is too much carbon deposit before cleaning, and clean it up if there is too much. However, it is not necessary to remove carbon deposits at regular intervals, which may affect the performance of the engine.
Brake maintenance package
The easiest way to maintain the brakes is to replace the brake pads, but many car owners will be fooled into making brake maintenance packages and adding some brake ointment or brake pad cleaning agent. In this way, the cost of replacing brake pads will increase a lot, allowing car owners to pay more.
