Washing your car in the hot sun - it hurts your car paint

Many car owners like to wash their cars in the hot sun, thinking that they will soon dry their cars. It is wrong actually, wash a car in burning sun, the convex lens effect that water droplet place forms can make the topmost of car lacquer generation local high temperature phenomenon, time is long, car lacquer can lose luster.

If at this time wax, also easy to cause the body color is not even. So, wash a car to wax had better be below the condition that has shelter to undertake, if cannot assure, had better choose in overcast day or sunny morning, late afternoon undertakes.


Too much oil - out of order

When the engine oil sump oil is insufficient, bearing and journal friction due to the amount of oil and poor lubrication, aggravating wear, and even lead to burning tile shaft accident.

But, if the oil is too much, the engine in the work of the crankshaft, the large end of the connecting rod will produce violent agitation, not only increased the engine internal power loss, but also will make the oil splashed on the cylinder wall increase, the production of exhaust oil fault. Therefore, the oil in the engine oil sump should be controlled in the oil ruler between the line.

Bolts too tight - permanent deformation

There are many fasteners connected with bolts and nuts on the motor vehicle. It should be ensured that it has enough pre-tightening force, but it cannot be screwed too tight.

If the screw is too tight, on the one hand, it will cause permanent deformation of the connector under the action of external forces; On the other hand, it will make the bolt produce permanent deformation of tension, pretension decreases instead, and even cause the phenomenon of slipping or breaking.

New batteries do not charge - shortens life

The first charge of the battery is called the initial charge, which has a great impact on the service life of the battery. If not charged, that is, add "water" direct use, the capacity of the battery is not high, life will be shortened; If direct charge, also can shorten life.

Usually the first charge of the battery is after filling the electrolyte, charging with a small current about 1 hour can be installed and used.

Add the equipment on the car at will -- affect the driving safety

The pursuit of comfort and luxury is beyond dispute, but some owners of their own hands in the car with a variety of equipment, such as modification of some audio, other electronic equipment and so on, if not properly handled, the performance of the car and easy to leave sequela or affect the safety of driving.

Cooling water temperature is too low - wear out engine

The weather is hot in summer, in order to prevent the temperature of the water-cooled engine is too high, blindly requires the temperature of the cooling water as low as possible; Some drivers to achieve the purpose of cooling, the engine cooling system to change the state of extreme cold, these practices are wrong.

Water-cooled engine is afraid of heat and cold, if the temperature of cooling water is too low, will make fuel combustion deterioration, fuel consumption increase, aggravate wear, oil viscosity increase, engine power reduction.

The test shows that when the temperature of cooling water is 40 -- 50 degrees Celsius, the engine wear increases 60% -- 80%, the power decreases 25%, and the fuel consumption increases 8% -- 10%. Therefore, the temperature of engine cooling water is not the lower the better.

Long - term use of vehicles or short - distance vehicles - damaged parts

Some people usually "not willing to" drive their own car, like some more expensive cars, generally only when the holiday to drive out to play, in fact, such a car way is very hurt the car.

Engine and gearbox and other transmission parts of the surface will often be in direct contact with the air state and rust, battery will also affect the service life because of long-term natural discharge.

The best way is to run every few days for 30 or 40 minutes. In addition, for some specific run long distance or specific road motorcycle, if always a short distance car will also hurt the car, the car is always moving but not far away, is an important reason for the car injury
