The More Expensive Oil Is Not A Better Vehicle Maintenance And Four Errors

Into the summer day, hot it

Into the summer day, hot it. In this season, air-conditioning does not cool Puncture ... ... Vehicles, various problems are endless annoyance to vehicle owners. Some owners said that before the arrival of summer has given Car Maintenance done, how could this kind of problems? I recently consulted a number of

Vehicle Maintenance Found that some of the vehicles problems and errors related car, vehicle owners should be concerned about.

A misunderstanding: the cooling water temperature the lower the better?

In summer, the engine of the working environment becomes more severe, many car owners in order to prevent engine overheating, the engine will try every means to cool, and even the owner will be removed thermostat, can be described as anti-"boil" the obvious supernatural powers. In addition, some owners believe that the tank car can be water in summer, winter " Antifreeze "Only defense" frozen ", summer, no useful here. According to the hippocampus

car service personnel, they know some one-sided, some are wrong. Engine temperature is not lower the better, if the cooling water temperature is too low will reduce fuel combustion and increase Fuel consumption , Increased engine wear and ultimately reduce engine power. At the same time, the engine performance is very excellent Travel Working conditions of the engine computer has accurate control, and then like to deal with "classic cars" on the thermostat as "hands and feet" is not necessary. Service experts also stressed that the antifreeze is not just "freezing" so simple, antifreeze boiling point higher than the water in the hot summer months, changing the water or water mixed with antifreeze for the engine cooling, but easy to "boil."

Solution: have the best engine operating temperature, when the cooling water temperature control 80 to 90 allows the engine to achieve the best working condition. Owners should be replaced once a year Coolant If not promptly replaced the boiling point will make your car down there, anti-corrosion performance degradation and so on.

Misunderstanding 2: air conditioning not cool to add refrigerant

Found that air conditioning is not cool, the owner's first reaction is "lack of fluoride," the car was open to direct 4S shop Add refrigerant, or repair station requirements. But in fact, add refrigerant if blindly without testing, may cause excessive air conditioning refrigerant pipe, but will make the system undesirable heat, air conditioning not cool more. In fact, except air conditioning does not cool

"lack of refrigerant", there are the many other possible causes, such as air conditioning filter plug, dirty air will result in not cool, air volume decreases.

Solution: vehicle to replace air conditioning filter in time, the brand has a regular replacement cycle, the timely replacement of filter can increase the amount of wind capacity and get rid of the smell. If the owners feel that smell blowing air conditioning, air conditioning duct may be caused by mildew, etc., in order to protect the health of this case be on the air conditioning duct cleaning.

Some travel tips for air conditioning can also be achieved with greater efficiency. Vehicles in the outdoor exposure, do not rush to air conditioners, window air can first, so slightly smaller then the inside temperature of air conditioners, use the inner loop, so that the car cool down quickly. Running for some time, be more comfortable when the temperature inside the car, and then use the outer loop, you can keep the car's air fresh.

Misunderstanding 3: The more expensive the better lubricant

Typically, owners like to use to measure the oil price and the brand is good or bad, but professional point of view, not the choice of lubricants is to take better care of your car, not all of the oil are suitable for use in summer .

Solution: as we choose the higher grade after the two oil. According to reports, a good oil to SAE viscosity grade and API according to the quality level to select. If the API quality level has been fixed, oil change, pay attention to packaging the SAE viscosity grade mark. To "SAE10W-40" as an example: SAE viscosity grade is, W means the oil used for winter, W in front of the number of smaller, indicating that low-temperature liquid lubricants better and better cold-start lubrication; Figures 10,20,30,40 and so refer to the back of the viscosity of the size, the larger the number, the higher the viscosity of said high temperature.

In daily use, not insist on expensive oil and the use of a good oil, the wrong label will hurt the car. The correct approach is specified by the manufacturer's label in the range of options lubricants. Winter can choose the extent permitted by relatively low viscosity oil; summer, by contrast, can choose a relatively high viscosity lubricant.

Mistakes 4: Reduce tire pressure to prevent puncture

Puncture prevention that summer, some old novice drivers often choose to lower tire pressure recommended to avoid the risk of puncture. In fact, the lower tire pressure and sometimes even more dangerous than the tire pressure is too high.

This is because now most of motor vehicle tires radial tires. This tire carcass, is cross-polymer multilayer material, the top layer of several layers of steel cord fabric woven from the wire. If the tire pressure enough, these wire variant volume on the increase, in a short time will have a lot of heat, this is the real cause of the summer flat tire.

Same time, the tire pressure is also directly related to traffic safety. Tire pressure too low or too high will cause the vehicle driving force and braking performance, driving stability decreased. Low tire pressure will make cars more fuel fee.

Solution: better go to 4S store owners or regular repair shop, regular inspection, adjustment of tire pressure, tire pressure at the factory to keep within the limits prescribed. Particularly long-distance travel before the summer, but to double-check on the tires, in addition to tire pressure, the tire wear, damage matrix need attention, not "sick child" on the road. Ordinary car owners can also prepare a pen-type tire pressure, tire pressure monitoring at any time. If the owners of capital

more abundant, but also sufficient nitrogen for the tires and spare tire. Nitrogen is inert diatomic gas, very active chemical properties, low coefficient of thermal expansion, low thermal conductivity, temperature changes, low volume expansion than air, reducing the risk of puncture. Nitrogen tire filling distortion when driving, ability to improve grip and reduce rolling resistance and reduce fuel consumption.

The face of sustained high temperature weather, vehicle owners should note that in addition to the above four errors in the hot summer to do a car targeted the "Health Check" is the top priority. Currently, the domestic auto service brands have launched many summer car maintenance services. A wealth of activities and professional services products that can help your car easily aestivation.
