The tightness of the fan belt should be suitable. If the tension is too tight, the bearing load will be too large, the wear will be intensified, the power consumption will increase, and even the pump shaft will be bent, the belt will be elongated and deformed, and its life will be shortened.
The oil can be between the upper and lower scale lines of the dipstick. If there is too much oil, the crankshaft handle and the big end of the connecting rod will produce severe agitation when the engine is working, which will increase the internal power loss of the engine and even cause the burning oil to malfunction. When the oil in the engine oil sump is insufficient, the friction between the bearing and the journal will be poorly lubricated due to the small amount of oil, which will aggravate the degree of wear and even cause a burnt shaft accident.
Cooling water temperature is low
In the summer, some car owners believe that as long as the cooling water is low, the engine temperature can be avoided. In fact, if the temperature of the cooling water is too low, the fuel combustion will deteriorate, the fuel consumption will increase, the engine wear will be aggravated, the viscosity of the oil will increase, and the engine power will decrease. Therefore, the temperature of the cooling water should be appropriate, between 80-90 degrees Celsius.
In summer, the temperature rises, the dust increases, the body is easy to be dirty, and the frequency of car washing is also beginning to rise. When washing the car, it is necessary to keep the appearance of the car air conditioner dry. If the car air conditioner is accidentally wet, it will affect the life of the car air conditioner.
Also remember not to wash the car under the scorching sun, this will hurt the paint surface, because the water droplets on the surface of the car body will form a convex lens under the sunlight, causing damage to the paint surface. If the car is waxed at this time, then There will be uneven color of the paint surface.
