Four misunderstandings about maintenance errors of Huangjiang imported cars
Misunderstanding 1: engine oil is more essential
Do not add more or less oil in the crankcase. Too much oil will increase the rotation resistance of the crank connecting rod mechanism and increase the amount of oil splashing on the cylinder wall. Too much oil will cause carbon buildup in the combustion chamber and reduce engine power, which will affect emissions. When checking or adding oil, the owner should add the oil according to the scale above the oil scale. The highest oil level cannot exceed the upper limit of the scale and the lowest cannot be lower than the lower line of the scale. The oil level is usually added to the upper middle position More appropriate.
Misunderstanding 2: Tire pressure should be higher than low
Some owners like to inflate the tire pressure very high, thinking that it can overload and save fuel, which is incorrect. Excessive tire pressure will reduce the tire ground contact surface, increase tread wear, and reduce the braking effect during braking, which will affect driving safety. Too low a tire pressure is not good. In addition to a low tire pressure, which will affect driving safety and braking effects, it will also accelerate the wear of the tire shoulders and increase the fuel consumption of the vehicle. When using the air pump to self-inflate, the owner should inflate according to the air pressure specified by the manufacturer. The tire pressure label of imported tires on Huangjiang is usually located on the body or the fuel tank cap.
Myth 3: Wheel screws are better than loose
According to different diameters, pitches and applications, the tightening torque of the bolts in various parts of the car are correspondingly specified. Bolts that do not reach the specified torque will loosen, and bolts that exceed the tightened torque will be stretched. Before tightening each component, you need to grasp the tightening torque of each bolt.
Myth 4: Don't loosen the accessory belt
Some car owners believe that increasing the tension of the accessory belt can improve the cooling effect of the compressor and the power generation of the generator. Therefore, they have been constantly improving the belt tension. This method is wrong. The accessory belt should maintain proper tension, because too tight a belt will cause excessive bearing load, shorten the service life of components, and cause the belt to break, which will eventually affect the normal use of imported Huangjiang vehicles . http://gufemba.com/
