With the popularity of cars, car maintenance concept has been widely accepted, many people know that in accordance with the requirements of each automobile manufacturer with a certain mileage to do routine maintenance, such as oil changes, filters, check the brake system. But many people understand mechanical maintenance mileage using manual, thinking kilometer car did not go the specified number does not have to do maintenance, resulting in some of the annual mileage few (only a few thousand kilometers or less) long-term lack of vehicle maintenance , cause great wear. In fact, the manufacturer's recommended maintenance intervals only in exceptional circumstances, the vehicle to be maintained for the purposes of normal conditions of use in accordance with special regulations.
Long time no car or annual mileage little surface substantially no wear of the components, in fact, this way of working more damage to the vehicle. First, because in the long run the machine at low temperatures, poor lubrication and mixed gas doctrinal increased wear of the machine; in addition, long-term parking make oil, brake fluid, antifreeze, electrolyte oxidative deterioration, deformation of tires and rims, also There are such pests, rodents and other unexpected problems. Therefore, even if the vehicle is not how to open, at a certain time to do maintenance.
Long-term suspended car generally should pay attention to the maintenance of the following sections:
Oil and filter. On the surface, the chemical nature of the oil is very stable, but in fact, the oil container once opened, there may be oxidized, especially in stop-go of the car often state or the mileage every day is very short, oil oxidation The phenomenon is even more serious. After the oil oxidation, not only lubricating effect of greatly reduced, but also on the parts of some acidic substances cause serious corrosion. In addition, many of the oil have deteriorated precipitate precipitation, these precipitates can clog oil passages or the sub surface friction serious wear and tear. Therefore, even if the vehicle did not reach the maintenance mileage, but also every other year and change the oil filter. antifreeze. Antifreeze replacement standard is not with the number of miles but the length of time, or, more precisely, the number of starts. Because the machine from cold to hot and then cold, such a cycle would make antifreeze aging time, accumulated to a certain number of times, antifreeze must be replaced. In addition, the long-term without antifreeze, especially water-based glycol antifreeze will degenerate, therefore, up to two years, antifreeze must be replaced once.
Brake oil. Brake oil in the water very sensitive, once mixed with water, the continuous braking when it is prone to air resistance, which is very dangerous, in addition, deterioration of oil will corrode the brake master cylinder, slave cylinder rubber components.
If the vehicle must be long-term suspended for some reason, then the conservation measures taken also from short-term parking. Before storage, the net should be placed all the antifreeze in the cooling system, release the oil, batteries should be fully charged off the trailer coupling, during the park should be regularly charged. In addition, application of robust rack jack the car up, the tire and suspension components are no longer the force. During the long-term car park, very sensitive to two things: First wet, two rodent. Not only will wet metal corrosion, but also damage the electrical components, which for a high degree of automation car is fatal. Rodents Many people may disagree, but it's destructive power often beyond people's imagination. Wires, tires, interior parts will become their mouth food.
Having said that, the main hope that we understand that even a motionless car also damaged, also needs maintenance, do not think that the car to a stop Curry, the door lock to get away shop.
