But do wrong, the car in the sun, the water formed by the convex lens effect will make the top to produce local high temperature phenomenon of paint, a long time, the paint will lose luster. If at this time also easy to cause the body waxing, uneven color. So, it is best to wash the car wax in sheltered conditions, if not guaranteed, it is best to choose in the cloudy or sunny morning and evening. 2. car wash like bath and air conditioning With the weather warming, dust increase, body easy dirty, car washing frequency also began to rise, many owners in the car would like to wash herself as made thoroughly. But to note here is, must maintain the appearance of automotive air conditioning dry, if the car air conditioning accidentally get wet, will affect the life of car air conditioning. 3. - circle waxing effect A lot of people to wax vehicle used to circle the way, this is not the right way. The correct way is waxing in a straight line, horizontal and vertical lines alternately, according to the water flow in the direction of the last one, so as to reduce concentric circles the car paint surface effect. 4. too much oil - failure When the engine oil pan of oil shortage, bearing and shaft neck friction due to oil less lubrication, aggravate the wear degree, even cause the burning bearing accident. However, if too much oil, the engine crank handle at work, the connecting rod will produce violent agitation, not only increases the power loss inside the engine, but also make a splash onto the wall of oil increases, resulting in burning oil discharge fault. Therefore, the engine oil sump oil should be controlled between the oil foot and under the line for good. Permanent deformation of bolt tight - 5. Bolt, fastening nut connecting pieces on many cars, should ensure enough pre tightening force, but also can not be overdone. If overdone, one hand will make connections under the action of external force to produce permanent deformation; on the other hand will make bolt produce tensile permanent deformation, but the pretightening force drop, even cause slipping or breaking phenomenon. 6. fan belt is too tight - bearing load Some drivers think that improve the fan belt tension, can improve the engine cooling effect, therefore a lot of improve the fan belt tension, causing the fan belt is too tight, not knowing that it is wrong. The fan belt should maintain proper tightness, because too tight will make the bearing load is too large, wear, power consumption the increase, but also make the water pump shaft bending, belt stretching deformation, shorten the life of. 7. tire imports - not applicable Some people buy tire special love "import", but stressed that the new tire to push foreign domestic users is one of the most fatal flaw is not applicable. The flat pavement is quite different with the domestic conditions for Europe road tyres at home is difficult to have a good performance, especially the impact of side is obviously a bit like Italy famous The climate does not suit one., wearing leather shoes walking gravel, the side of the tire from the package are inevitable. Some foreign brands in the domestic tire production joint venture, according to the domestic situation in the tire side adds a layer of cord fabric so as to greatly increase the tire side impact resistance, joint production of tires from a performance perspective can completely replace imported goods. 8. new battery charging is not - shorten life The first battery charge is called the first charge, the first charge has great influence on the service life of the battery. If you do not charge, with "water" used directly, the battery capacity is not high, life will be shortened; if the direct charge, will shorten the life of. Battery charging is usually first in filling the electrolyte, with a small current charging 1 hours can be installed to use. 9. cooling water temperature is too low, the engine wear When the weather is hot, some drivers in order to prevent the engine temperature is too high, demanding the cooling water temperature as low as possible; Some drivers in order to achieve the purpose of cooling, simply remove the thermostat, these practices are wrong. Fear of both hot and cold engine, if the cooling water temperature is too low, can make fuel combustion deterioration, increased fuel consumption, increased wear, oil viscosity increase, reduction of engine power. Experiments show that when the vehicle is running water cooling temperature is 40-50 degrees Celsius, engine wear increased 60%-80%, power is reduced by 25%, fuel consumption increased 8%-10%. Therefore, the engine cooling water temperature is not as low as possible, the general should be controlled between 80-90 degrees celsius. 10. tank boil water - cylinder cracking speed Some drivers saw the tank "boil" phenomenon, to reduce the engine temperature, immediately turn off the water. This is wrong, it may cause the cylinder cover because of the sudden cold cracking phenomenon. See if the tank "boil", generally the correct way is: stop immediately, keep the engine speed. The cooling water temperature is reduced, then the engine flameout. If the cooling water shortage, slowly add, to prevent the cylinder cover due to a sudden cold and cracking
