It is very different from new car maintenance and teaches you common sense of used car maintenance

It is very different from new car maintenance to teach you the common sense of second-hand car maintenance. With the continuous blowout of the car market in the past two years and the gradual release of the demand for car replacement, the current mechanical seal factory used car market is showing an unprecedented prosperous appearance. Along with the aging of shopping malls and the changes in car buying concepts, many consumers who have bought cars for the first time have also turned their attention to second-hand cars. Although second-hand cars are attracting more and more attention from us, technical issues such as second-hand car maintenance, due to the lack of professional knowledge, have generally become problems that confuse consumers. Below, Qiyang second-hand car technical experts will briefly explain to us the general maintenance of several important system seal factories for cars, and after inquiring about certain conditions of the vehicle to determine whether special maintenance is required. 1. Cleaning and maintenance of the fuel system. Under normal circumstances, a car needs to be cleaned and maintained with a mechanical seal every 10,000 to 15,000 kilometers, or when you find the engine is trembling, lagging, poor acceleration, black smoke, weakness, Clean and maintain 1 time when oil is consuming. Eradicate the colloid and carbon deposits inside the system, prevent harmful corrosion, prevent and obstruct the leakage of seals and water tanks, and completely replace the old coolant. 2. Deepening maintenance of the lubrication system The primary function of the lubrication system is to provide useful lubrication to the various parts of the car recommendation machine to prevent excessive wear. Under normal circumstances, the car needs to be cleaned and maintained once every 5000 to 10000 kilometers of travel. When the recommended machine noise is too large, the acceleration is weak, and the water temperature is too high, it also needs to be cleaned and maintained once. It is recommended to clean the sludge and other deposits inside the recommended machine to prevent the oil from oxidizing and thickening at high temperatures, reduce the wear of the recommended machine parts, extend the recommended machine life, and move forward to recommend the machine power. 3. Cleaning and maintenance of the cooling system. Under normal circumstances, the car should be cleaned and maintained once during the winter and summer seasons, and once every 6 to 8 months during the normal trek. It may be cleaned and maintained once when the water temperature is too high, the water leaks, or the pot is boiling. . Eradicate the traces and scale that caused the recommended machine to overheat, prevent harmful corrosion, prevent and obstruct the leakage of seals and water tanks, and completely replace the old coolant. 4. Maintenance of the power steering system. The car needs to be cleaned and maintained once every 40,000 to 45,000 kilometers traveled, or the system leaks when the steering is difficult, after replacing the power steering gear parts, it must also be cleaned and maintained once. Eliminate harmful sludge and paint film in the system, eradicate steering difficulties at low temperatures, obstruct and prevent leakage of power steering fluid, eradicate steering noise, and completely replace old brake steering fluid. V. Gearbox cleaning and maintenance The car is cleaned and maintained once every 20,000-25,000 kilometers, or when the gearbox is slipping, the water temperature is high, the gear shift is slow, or the system leaks. Eliminate harmful sludge and paint film deposits, heal the elasticity of gaskets and O-rings, make the gearbox shift smoothly, forward power output, and completely replace the old automatic transmission oil.
