9. Arbitrary addition of equipment in the vehicle — affecting driving safetyPrivate cars are the mobile home of car owners. It is understandable to pursue the comfort and luxury of riding. However, some car owners install various equipment in the car by themselves.
Eight, water tank “open pan” quick add water — cylinder crackingWhen the weather is hot, some drivers see the water tank “open the pan” phenomenon, worried about the engine temperature rise again, immediately shut off and add water.This is a mistake and it is likely to cause the cylinder head to crack as a result of sudden cold.If the water tank encountered “open the pot”, the general correct method is: immediately stop the engine to keep idle to continue cooling;Open the hood at the same time, improve the heat rate.When the temperature of the cooling water drops, turn off the engine.If the amount of cooling water is insufficient, it should […]
Bolts are too tight — permanent deformationThe tightness of the belt can improve the cooling effect of the engine. Therefore, the tightness of the fan belt is constantly increased, resulting in the over-tightness of the fan belt.Fan belts should be kept tight, as over-tightening will lead to excessive bearing load, increased wear and power consumption, as well as bending the pump shaft, elongating the belt and shortening its life.
Cooling water temperature is too low – wear down the engineWhen the weather is hot, some drivers insist that the temperature of cooling water should be as low as possible to prevent the engine from being too hot.In order to achieve the purpose of cooling down, some drivers simply remove the thermostat, these practices are wrong.Automobile engines are both afraid of heat and cold. If the temperature of cooling water is too low, fuel combustion will deteriorate, fuel consumption will increase, aggravating wear and tear, engine oil viscosity will increase, and engine power will decrease.The test shows that when the temperature of cooling water is 40-50 degrees Celsius, the engine […]
Too much oil — it doesn’t workWhen the oil in the engine oil sump is insufficient, the friction between the bearing and the journal will cause bad lubrication due to the low amount of oil, aggravate the degree of wear and even cause the accident of burning tile shaft.However, if the engine oil is too much, the crankshaft handle and connecting rod end will produce violent stirring during the operation of the engine, which not only increases the internal power loss of the engine, but also increases the oil splashed on the cylinder wall, resulting in the fault of burning exhaust oil.Therefore, the oil in the engine oil sump should […]
Circle waxing — bad effectA lot of people are used to waxing cars in circles, which is not the right way to do it.The correct way of waxing is to be carried out in a straight line, alternating horizontal and vertical lines, and then on the last line in the direction of rain flow, so as to achieve the effect of reducing the concentric circular ring on the surface of car paint.
