"Five oils" refer to engine oil, brake oil, automatic transmission oil (automatic vehicle), gear oil (manual vehicle) and differential oil; "Sanshui" refers to cooling water, wiper water, and battery water Generally, car owners are familiar with the inspection and replacement of engine oil, but other items are equally important and should not be taken lightly.

The world-renowned car maintenance center said that the automatic variable tank oil is responsible for power transmission and lubrication.transmissionFor this purpose, the oil quantity should be checked every 5,000 kilometers, and replaced every 20,000 kilometers or a year. It is best to use an oil changer to drain the old oil when replacing it. The magnets and filters that absorb metal chips and impurities are taken out and cleaned, and then new oil is injected. The selection of gearbox oil should refer to the specifications recommended in the automobile user manual, and adopt products with high shear resistance and stable quality.

In addition to the regular replacement of the automatic gearbox oil, Castrol also recommends that you can check it yourself at any time.The first is that the engine must reach operating temperature, step on the brakes, put each gear to P, then open the hood and take out the amount to check.

The owner can design and drive according to the brake system of the car. It is customary to choose, and the characteristics of the oil should consider the anti-steam lock performance.

Finally, cooling water is used to increase the boiling point of water and lower the freezing point to maintain the cooling effect, prevent rust and scale, and protectWater pumpPu preventionThermostatThe valve is stuck, and lubrication protects the waterway.It must be replaced every 20,000 kilometers or a year, and it must be checked and added frequently on weekdays. The check method is to check when the working temperature is reached.Water tank, It is normal that the water level reaches the marked upper limit, and it is not right to pass or fail. (Dahe Net)
