60,000 kilometers is an important node of maintenance. Some car owners not only spend more money, but also hurt their cars because they don’t understand. What specific parts need to be replaced or maintained? Let’s listen to what the maintenance master of the 4 S shop has to say.
1. Replacement “Five oils, four filters, three liquids and one water”
1、“ Five oil “Are respectively Engine oil, brake oil, transmission oil, power steering oil, clutch oil 。
Nowadays, family cars generally use fully synthetic engine oil, which can be changed every 10,000 kilometers or once a year. Needless to say, the engine oil can be changed on time and according to the quality, but other items are easy to ignore.
Brake fluid Generally, it is checked and replaced after about 2 years or 40,000 kilometers, and it is found that the braking distance becomes obviously longer and unstable, and the brake pedal becomes soft. At this time, you need to check the brake fluid, and you can open the cover of the brake fluid. If the brake fluid becomes turbid and turns black, it needs to be replaced in time.
Generally, repair shops check the moisture content of brake fluid through brake fluid detectors. It is normal for the moisture content to be in the range of 0.5%-2.5%. When the moisture content is greater than 3%, it needs to be replaced immediately.
Transmission oil, generally speaking, is replaced every 3 years or 60,000-80,000 kilometers for manual transmissions, while slightly earlier for automatic transmissions, every 2 years or about 60,000 kilometers. Of course, this is a rough cycle. The specific determination still needs to be based on factors such as vehicle model, gearbox structure, and driving habits.
As for power steering oil, it is mainly the models more than 10 years ago, and mechanical power is generally used. However, today’s family cars are generally electronically assisted and do not need power oil.
Similarly, clutch oil is mainly for manual transmission models. In most models, brake oil and clutch oil share an oil pot, and the replacement cycle is the same. Of course, different models have different situations, such as off-road vehicles and differential oil.
2、“ Four filters “Are respectively Oil filter, fuel filter, air conditioning filter, air filter 。
Generally, the oil filter element is changed together after the oil is changed. In fact, the replacement cycle is similar to that of other filter elements, which is replaced every 20,000 kilometers or 1-2 years. However, this is not a hard requirement, and it depends on the actual usage.
For example, if you often drive on mountainous areas and non-paved roads and have a lot of dust, the air filter element can be properly checked and replaced in advance. For another example, if the air conditioner is hardly turned on for a year, the replacement cycle of the air conditioning filter element can be appropriately extended.
3、“ Three liquids 1 water “They are antifreeze coolant, battery liquid and glass water.
The replacement cycle of original car antifreeze varies greatly. Some car maintenance manuals require that it needs to be replaced every 2 years or every 40,000 kilometers or so, but many models use long-lasting antifreeze, which is replaced every 5 years or 100,000 kilometers. This category accounts for the vast majority of models.
Some models also use “permanent” antifreeze, which is replaced every 10 years or 200,000 kilometers, such as Honda, Audi and other models. Some car companies even directly say that there is no need to replace antifreeze, and there is no replacement in the maintenance manual. Antifreeze liquid item.
Antifreeze is very important, so many new cars use high-performance antifreeze with a long service life. For daily use, you can check the remaining amount of antifreeze through visual inspection. The antifreeze of most models is purple-red, and the antifreeze kettle is marked respectively. The highest liquid level of MAX and the lowest liquid level of MIN. When you see that the liquid level is lower than MIN, add antifreeze in time.
2. Tire replacement cycle
Generally speaking, automobile tires can be used for 5-8 years or travel for 50,000-100,000 kilometers. These values are not absolute and need to be determined according to the actual usage. Road conditions, driving habits, maintenance, tire quality and other factors will affect its specific life.
Tire grooves are generally designed with wear indicator points. If the tire is found to be seriously worn, it needs to be replaced in time when it is almost reaching the indicator point. Check the tire daily for cracks, bulges, etc. If the cracks are large and deep, there is a bulge, it must be replaced in time.
3. Braking system
The braking system mainly depends on Brake pads, brake fluid, brake discs As mentioned earlier, the brake oil should be checked and replaced in due course. The thickness of the brake pads is generally about 1.5 cm. When the naked eye sees that the brake pads are only about 1/3 thick, it is necessary to pay attention to the timely replacement at all times. Some models cannot be viewed by the naked eye due to the wheel hub, and need to be disassembled to see the thickness of the brake pads.
If it is a front-wheel drive vehicle, the front wheel brake pads generally wear faster than the rear wheels. Check every 40,000-60,000 kilometers and replace them in time if necessary. Similarly, the rear wheels of rear-wheel drive vehicles wear faster, so you need to pay more attention to the rear wheel brake pads. As for brake discs, the general replacement cycle is about twice that of brake pads.
In daily driving, if you find that the braking distance becomes obviously longer, you feel a little difficult when stepping on the brakes, and the brake pedal is a little soft. At this time, it may be that the friction of the brake pads is not enough and unstable. You should check the brake oil and brake pads in time.
You can also judge by listening to the sound. There are wear limit marks on both sides of the brake pads. When the brake pads are worn to the limit marks, there will be a faint sound or clamor when stepping on the brakes. However, sometimes there is water on the brake disc or it is not clean, especially in winter, after rain and sunny, and it will make abnormal noises when you first drive, and it will return to normal after stepping on the brakes several times. This is normal.
4. Other parts
In addition to the common wearing parts above, there are also Spark plug, ignition coil, timing chain, three-way catalytic converter Etc. and other daily maintenance items.
There are many types of spark plugs according to their materials. For example, ordinary nickel alloy spark plugs generally need to be inspected and replaced after 20,000-40,000 kilometers. In addition, there are platinum spark plugs, iridium spark plugs, iridium platinum spark plugs, etc. For example, iridium platinum spark plugs generally need to be inspected or replaced after driving more than 100,000 kilometers. Many car companies even directly say that their models do not need to replace spark plugs.
Automobile ignition coils generally have a long service life and only need to be replaced every 100,000 kilometers or more. As for timing belts and timing chains, in the past few years, many models used timing belts, which were checked and replaced about 80,000-100,000 kilometers. Now Most models use timing chains, and the replacement cycle is longer. Many car companies claim that there is no need to replace them for life.
Three-way catalytic converters are generally inspected and cleaned after 80,000-100,000 kilometers. For older models, the exhaust gas detection may fail due to problems with the three-way catalytic converter during online testing. At this time, they need to be inspected, cleaned or replaced.
As for maintenance items, for example Engine carbon deposits, fuel injectors, throttle valves, oil pipelines Other items can be judged according to the actual vehicle situation and the specific problems of the vehicle. Many 4 S shops or repair shops recommend these maintenance items, mainly because of their high profits.
Some novice drivers, when they get their first insurance Clean engine, throttle valve, fuel injector Waiting for projects, to put it bluntly, is a waste of money, which is completely unnecessary. If the economic situation is considered, under normal circumstances, these projects do not need special maintenance.
In short, the car’s mileage reaches about 60,000 kilometers. “Five oils, four filters, three liquids and one water”, tires, brake pads, brake fluid These items need to be paid attention to and replaced in due course, and other parts also need to be inspected.
Some car owners may say that their car has traveled 80,000 kilometers, except for the oil and filter, nothing else has been replaced, and everything on the vehicle is normal. To be honest, this is a kind of “fluke” psychology, and car maintenance belongs to “taking precautions”. Some parts and wearing parts can indeed be used although they exceed the maintenance period for a long time.
But the problems all accumulate slowly. After a long time, all kinds of big problems will come. By then, it will be too late to regret the overhaul. More importantly, the driving safety problem. Therefore, it is necessary to carry out maintenance on time and with quality. Since you choose to buy a car, don’t be stingy with maintenance costs.
