I bought my first car in 2015, and although it's been more than 7 years, I still remember my feelings when I first came into contact with my car. Unconsciously, this car has traveled 100,000 kilometers, for ordinary family cars, 100,000 kilometers is a hurdle, more than 100,000 kilometers later, the car began to appear a variety of small problems, engine oil leakage, transmission noise, chassis deviation, tire partial grinding, etc., and these seemingly difficult to solve problems, but the owners did not correctly carry out routine maintenance of the car caused, 100,000 kilometers after the car, what maintenance is needed? "Automotive Overview" to explain to you carefully!
Replace the engine oil model
The small maintenance of the car, also known as the replacement of one oil and three filters, engine oil, engine filter, intake filter, air conditioning filter. For the replacement of engine oil, car owners often choose a fixed style of oil, of which, 5W-30 oil has become the favorite of most car owners, but do you know that after 100,000 kilometers of vehicles, the engine needs to choose a slightly higher viscosity oil during maintenance, 5W-40 has become a new choice for car owners, the reason is very simple, after the engine works for a long time, the gap between the various parts becomes larger, and the oil with a higher viscosity coefficient has a better protection effect on the various parts inside the engine.
Replace the engine timing belt
In the engine crankshaft position are connected to the timing belt, after the vehicle travels 100,000 kilometers, the timing belt is seriously aging, if the owner insists on using this timing belt at this time, it is likely to break, slip and other phenomena, thereby affecting the engine work efficiency, and even lead to abnormal damage to the engine, the replacement of the timing belt is often forgotten by everyone. The location of the belt is relatively private, it is difficult for the owner to replace it, if you go to the 4S shop for maintenance one day, remember to find a technician to help you replace it.
Replace the transmission oil
In addition to the engine oil needs to be replaced, the transmission oil also needs to be replaced, but its replacement cycle is very long, 100,000 kilometers is just a hurdle, after all, after a long time of transmission work, there will be abnormal wear between its internal parts, and the wear residue will be left into the transmission oil, the owners in the driving vehicle, if you find that the gear change is frustrated, the transmission has abnormal noise and other issues, you can consider replacing the transmission oil.
Four-wheel positioning of the chassis
Under normal circumstances, after the mileage of 100,000 kilometers of vehicles, its chassis will be more or less damaged, resulting in poor chassis driving stability, the steering wheel of the vehicle has a slight deviation phenomenon, in serious cases, the tires of the car will be biased, that is, we often say that the phenomenon of eating tires. After driving 100,000 kilometers, the owner can give his car a four-wheel positioning and re-calibrate the chassis system, which is also a maintenance project that the vehicle must complete after 100,000 kilometers.
The above maintenance items are very important, but it is also very easy to be forgotten by the owner of the content, in addition, the mileage of more than 100,000 kilometers of vehicles, a variety of large and small maintenance items should be carried out again, such as brake oil, brake pads, tires, engine coolant, ignition coil, air conditioning refrigerant, etc., these are also the most basic, owners can be aware of the problem, here do not elaborate.
