I haven’t written the details of the next few maintenance for a long time. Today, I will tell you the details of the next three maintenance.
Fourth maintenance:
The fourth maintenance is the longest I have done, it took a total of 5 hours, because this maintenance project is also very many, and then I will tell you about the specific projects in detail.
1. Routine basic maintenance:
The routine basic maintenance is the replacement of the engine filter and the 24 safety tests of the whole vehicle. This is also a must-do item for every maintenance. A car friend once asked me such a question: that is to say, if you use 0-W20 oil before and want to use 0-W30 oil in the back, is that okay? What I want to tell you is that the type of oil used before must not be changed easily, because it will do some damage to the engine. So here I also recommend you to use 0-W20 oil.
two。 Gasoline compartment replacement:
According to the maintenance manual, the petrol compartment is recommended to be replaced every 30,000 kilometers, but if most of your car is used in the city or refueled at a regular large gas station, you can change the gasoline compartment at 40,000 kilometers or 50,000 kilometers.
3. Tire dynamic balance detection and correction:
This problem should be one of the situations that I encounter most frequently, because the tires are often punctured by nails, so I don’t do dynamic balance every time in order to save time when patching tires. A long time will lead to vehicle body jitter at a speed of more than 100, and that kind of high-speed jitter will also have great safety risks. Under the test of 4S professional equipment, it is found that there is a gap of 20-30 between almost every tire and the standard value. The master said that the difference is usually 10-15. It is suggested that I should make a dynamic balance after every tire patch. Here I also suggest that you must do dynamic balance after mending the tire. Don’t try to save time and ignore this important thing as I do.
4. Air conditioning cleaning:
This is also my first time to clean it, because it happens to be done by 4S, so I clean it at the same time. But this is not a must, and I do not recommend this project because of the stagnant water in the pipes after cleaning, which leads to a great smell in the air conditioner.

Fifth maintenance:
Basically, I maintain it once a year or 10,000 kilometers. So it happens that the fifth year is also the maintenance of 50,000 kilometers, and 50,000 kilometers is also the major maintenance time of Volvo S90. With regard to the previous online rumors that Volvo S90 major maintenance costs tens of thousands of dollars, here I would like to explain to you, to be able to say such words is either malicious slander or just at this point to replace some parts, otherwise it is impossible for tens of thousands of major maintenance alone. Next, I would like to tell you about the detailed maintenance of 50,000 kilometers, and give you a reference.
1. Basic maintenance, I will not elaborate on this, because this is the necessary homework for each maintenance.
two。 Brake fluid replacement: 50,000 km for S90 maintenance. If the brake fluid has not been replaced before, 4s can be required to test the moisture content of the brake fluid. If the moisture content of the brake fluid is no more than 3%, if it exceeds it, it must be replaced. If you do not meet the standard of moisture content, you can decide whether or not to replace it according to your personal situation, but the owner’s maintenance manual recommends a replacement, so I also replaced it.
3. Gearbox oil replacement: it is suggested in the official maintenance manual that the gearbox oil needs to be replaced for 50,000 kilometers, so this time my gearbox oil replacement is also in accordance with the official maintenance manual. To change the gearbox oil, you need to lift the car first. By twisting the screws under the chassis, the old gearbox oil will be completely removed, the principle is similar to changing the oil. The gearbox oil of the original car can be seen black with the naked eye. In order to better protect the gearbox, the gearbox oil must be replaced at 50,000 km.
4. I replaced the air filter element and the air conditioning filter element at 50,000 kilometers, so I didn’t change them this time. And the gasoline compartment has also been replaced at 50,000 km, so this time it has not been replaced at 60,000 km.
Summary: each maintenance can refer to the car owner’s manual, in fact, Volvo maintenance price in terms of luxury brands is more affordable, and not as ridiculously expensive as rumored on the Internet. This is also all the details of my five maintenance in the past five years. I hope it will be helpful to you.
