The long-standing practice of "three parts repair and seven parts maintenance" in the automotive industry has highlighted the importance of car maintenance. For professional cars, how to maintain them in order to not only run smoothly but also achieve "immortality"? Industry experts remind us that it is necessary to maintain the six major systems of specialized vehicles.

1、 Deepening maintenance of lubrication system

The main function of the lubrication system is to effectively lubricate the various components of the specialized vehicle engine to prevent excessive wear. Under normal circumstances, specialized vehicles need to be cleaned and maintained every 5000-10000km. When encountering excessive engine noise, weak acceleration, or high water temperature, they also need to be cleaned and maintained once. Clean the oil sludge and other deposits inside the engine to avoid oxidation and thickening under high temperatures, reduce wear on engine components, extend engine life, and improve engine power.

2、 Cleaning and maintenance of the cooling system

In general, specialized trucks should be cleaned and maintained once during the winter and summer seasons. During normal driving, they should be cleaned and maintained every 6 to 8 months, or when encountering high water temperature, leakage, or boiling. Remove traces and scale that cause engine overheating, prevent harmful corrosion, prevent and stop leakage of seals and water tanks, and thoroughly replace old coolant.

3、 Cleaning and maintenance of the fuel system (i.e. cleaning nozzles and valve carbon deposits)

Under normal circumstances, specialized vehicles need to be cleaned and maintained once every 800km-1000km, or once when you notice the engine shaking, lagging, poor acceleration, black smoke, weakness, and fuel consumption. Clean the internal resin and carbon deposits of the system to prevent harmful corrosion, prevent and stop leakage of seals and water tanks, and thoroughly replace the old coolant.

4、 Cleaning and maintenance of the gearbox (automatic transmission gearbox)

Under normal circumstances, special vehicles should be cleaned and maintained every 800km-1000km, or in case of gearbox slippage, high water temperature, slow shifting, or system leakage. Remove harmful oil sludge and paint film deposits, restore the elasticity of the sealing gasket and O-ring, make the gearbox shift smoothly, improve power output, and completely replace the old automatic transmission oil.

5、 Cleaning and maintenance of the power steering system

Special vehicles need to be cleaned and maintained every 1000-2000km of driving, or if there is a leakage in the steering system due to difficulty in steering, after replacing the power steering gear accessories, they also need to be cleaned and maintained once. Remove harmful sludge and paint film from the system, eliminate steering difficulties at low temperatures, prevent and prevent power steering fluid leakage, eliminate steering noise, and thoroughly replace old brake steering fluid.

6、 Cleaning and maintenance of the braking system

Special vehicles should be cleaned and maintained every 800km, or if they experience premature or slow ABS reactions, they should be cleaned and maintained once. Remove harmful sludge and paint films from the system, eliminate the danger of failure in operation at ultra-high or ultra-low temperatures, effectively prevent brake fluid from deteriorating and expiring, and completely replace old brake fluid.
