Under the hot sun washing , hurt the paint . Car wash in the hot sun , the effect of water droplets formed by the lens will paint the top local high temperatures generated , over time , the paint will be lost to shine. Wash like bathing, harm air conditioning. Summer Body dirty easily , many owners like to wash themselves in the hope that , like a bath wash thoroughly . But to note here is that we must maintain the appearance of dry automotive air conditioning , auto air conditioning , if not careful gets wet , it will affect the life of the car air conditioning . Hengding wheel hub gives you nine errors vehicle maintenance tips : 1 Wash ─ hurt the paint under the sun Many private car owners prefer to wash under the sun , that this will soon be washed and dried the car body of water . Actually wrong men, and wash in the sun , the water formed by a convex lens effect will paint the top local high temperature phenomenon , over time , the paint will lose luster. If at this time waxing, are likely to cause uneven body color. So , car washing and waxing is best in sheltered conditions , if not guaranteed, it is best to choose a cloudy or sunny in the morning and in the evening proceed. 2 air-conditioned car wash like bathing ─ harm Encounter weather temperatures, dust increased , body easy to dirty , wash the frequency of the owners began to rise , many owners also want to be like when you wash bathe himself as thoroughly confused . But to note here is that we must maintain the appearance of dry automotive air conditioning , auto air conditioning , if not careful gets wet , it will affect the life of the car air conditioning . 3 ways waxing circle ─ poor Many people have the habit to body waxing in a circle way , this is not the right approach. Waxing is the right way to a straight line , alternating horizontal and vertical lines , and then the direction of the flow of rainwater last one , in order to reduce the paint surface concentric halo effect. 4 Oil too ─ failure When insufficient engine oil sump , etc. with the journal bearing friction and lubrication oil due to less poor , increased wear , and even lead to burn Wazhou accident. However, if too much oil , the engine crank handle , the big end of the connecting rod will produce vigorous agitation at work , not only increases the internal engine power losses, but also so that the oil spill on the cylinder wall increases, failure to produce oil burning row Thus , the engine oil sump should be controlled on the dipstick , and between the lower groove as well. 5 bolts tight ─ permanent deformation With bolts , nuts, fasteners connected a lot on the car which should ensure there is enough preload, but not over-tighten if tightened too much , on the one hand will allow connections under the influence of external forces permanently deformation ; hand will allow the bolt to produce tensile set , but decreased preload , and even cause the slider or break phenomenon . 6 fan belt tight ─ large bearing load Some drivers believe that increasing the fan belt tightness can improve engine cooling effect, so he kept improving the tightness of the fan belt , causing the fan belt too tight , not knowing that this approach is wrong. Fan belt tension should be maintained properly , because the bearing load is too tight will make big , wear and tear , power consumption increases, but also make the pump shaft bending , stretching deformation belt , shortened life expectancy. 7 . Imported tires ─ NA According Hengding wheel hub noted , some people prefer to buy tires special emphasis on " import" , but foreign push new tires for domestic users who have one of the most fatal flaw is not applicable. European road traffic and domestic flat is quite different for the European road tires in the country can hardly be a good performance , especially in terms of impact -resistant sidewall apparently some acclimatization , just like wearing Italian designer shoes to walk the gravel In general, the sidewall from the package is inevitable. Some foreign brands in the domestic tire manufacturing joint venture , are based on road conditions in the domestic side of the tire cord fabric adds a layer of impact force and thus greatly increasing the sidewall of the tire from the joint venture to produce a performance perspective can completely replace imported goods. 8 new shorten the life of the battery is not charging ─ Charging the battery for the first time is called the initial charge and the initial charge has a great impact on the battery life. If charged, adding that "water" direct use, the battery capacity is not high , life will be shortened ; if direct charging will shorten the life . The initial charge is usually battery After filling in the electrolyte , with a small current charging around big one hour to install and use. 9 cooling water temperature is too low engine wear ─ When the weather is hot , some drivers in order to prevent the engine temperature is too high , insisting the cooling water temperature as low as possible ; Some drivers in order to achieve the purpose of cooling , we simply removed the thermostat , these practices are wrong. Sensitive to heat and cold car engine only if the cooling water temperature is too low , the fuel burn will worsen , increased fuel consumption , increased wear , increased oil viscosity , engine power is reduced. Tests showed that the cooling water temperature is 40-50 degrees Celsius cars , engine wear by 60 % -80 % , power is reduced by 25% , fuel consumption increased by 8% -10 %. Therefore, the engine cooling water temperature is not as low as possible , the general should be controlled between 80-90 degrees Celsius.
