Similarly, tens of thousands of kilometers of cars have been run, some have never had major problems, and others have already built up maintenance fees. What is the secret of this? Of course, the quality of the car itself is good or bad, but full maintenance can really make the driving life longer. Engines often lubricated with oil will last longer. As time goes on, the oil is dirty, which will reduce or even lose the lubrication effect of the oil and accelerate the engine wear. Although synthetic oil lasts longer, it also drops or gets contaminated. If the engine oil is regularly changed and the proper grade of motor oil is used, the inside of your car engine can be cleaned and fully lubricated. When driving, the engine will consume oil and low engine oil will also increase engine wear. Therefore, please check the oil regularly and replenish the oil in time. The transmission of automatic transmission depends on the use of transmission fluid. The same is true for brake systems, steering systems, engine cooling systems, gearboxes, and front and rear. All kinds of lubricants required by cars are very important to your car. They will evaporate or leak down over time, so please replace and replenish them in time when the lubricating oil volume is low. You can find the type of lubricating oil for the car in the car user manual. If your car wants to be used as a trailer, you can consider installing a transmission coolers and often changing the transmission fluid. You can get a lot of information about your car in the user's manual. Please put it in the glove box, and you can read it from time to time. In addition, the user manual has a diagram of the engine room, and you will know how to check coolant, oil and transmission fluid. You can also learn how to replace the headlights or taillight bulbs, and how to start the car when the battery is dead. If you want to know how the four wheel drive system works, you can also find relevant information in the user manual. Even if you know enough about the car, you can learn new useful information in the user manual. Any small problem, if it can be found early, can be avoided, and it will save you a lot of maintenance costs. Always pay attention to the abnormal performance and sound of the car. Warning lights often light, engine temperature is higher than normal level, the car has oil leaking, bump or brake, abnormal noise, odor, driving feeling different, acceleration is not smooth, wheel splash lubricating oil, brake board feeling weird and so on, these little signs are the small signs should be checked and checked. If you live in a damp place and rust easily occurs, please protect your brakes, fuel supply and other chassis parts in time. Regularly clean vehicles to prevent corrosion in unclean areas. It will not cost much to replace wipers at least two years. Waxing cars often helps protect car paints and make cars look great. Timely paint and scratch the car to avoid corrosion to the car body. Once the metal inside the car is exposed, it will rust, which is more extensive than the repair of minor trauma points. Because there are many electronic devices and wires in the dashboard, central console and carpet, there is a need to keep the car clean and dry. Generally speaking, electronic equipment will become disaster if it meets water. When the car is clean and tidy, the car will smell fresh. Once the car is wet, the rubbish is not cleaned up in time, and the smell inside the vehicle is unpleasant. Under normal circumstances, the new air conditioning filter equipped with ten thousand to twenty thousand miles will need to be replaced. The air conditioning filter that has not been changed in time will also cause peculiar smell inside the vehicle. More understanding of the cleaning information in the car. If some functions do not have to be used, please close them so as not to increase the burden of cars. Regular test tire inflating condition. Because tire inflation will accelerate tire losses and increase. Improper tire pressure will accelerate the wear of the car's four wheel drive system. Too much tire inflation will speed up the loss of suspension systems and control parts. After the winter is over, please replace the general tyres in time, because the winter tyres will accelerate wear on the dry asphalt pavement. Use tires on a regular basis. Some tyres will sag or produce noise if they are not used regularly. If you feel that the effect of vehicle tyres is not as good as before, please adjust the front wheel every 1-2 years. Improper front wheel alignment causes tire wear, suspension system consumption and poor handling performance. Drive smoothly. All throttle acceleration will cause rapid loss and damage to many parts of the car. An acceleration from 0 to 60 is more expensive than a few months of steady driving. So is the quick brakes. Passing through the deceleration zone at high speed will damage the rim, bracing, suspension system and wheel bearings of your car. If you are driving a short distance every day, please drive to the freeway regularly. Because short distance driving can not fully heat the engine, it will accumulate moisture in the engine. Find a trustworthy, experienced repairman, or a reputable repair shop to maintain and maintain your car regularly. You can recommend it to your friend. A repairman who serves you regularly knows more about the needs of your car. He will do a better job and make you more satisfied. At least one year, go to the repair shop to check a car. There are many problems under the car. Only your car can be inspected when it is hoisted. You can choose to use only high quality or original (OEM) parts. In addition to regular oil change, you need to do some other maintenance for the engine. Air filters are required for every ten thousand to twenty thousand miles to travel. Every 60 thousand -9 miles or so, your car needs a new spark plug and other parts. Worn spark plugs may cause many problems, including increased engine power and ignition coil failures. The ignition line should also be replaced regularly. Some cars, for example, need to adjust the valve clearance. Many car timing belts need to be replaced regularly. If you want to change the timing belt, you can usually replace the pump because it only takes a little extra effort. You can find the inspection maintenance plan or consult your repair technician in the user manual.
