The maintenance of 100,000 kilometers of the 3 Series is a souvenir

9 The car is an 18-model 320Li. It is now just 100,000 kilometers away. When it was 80,000 kilometers away, I wanted to do a big health care. However, I was very busy at that time. Recently, I had some free time and bought some materials online. It happened that the 4s maintenance package needed to change the oil, so I gave the horse a good maintenance. As the saying goes, if you want a horse to run, you must feed it well. Keep a record of this maintenance so that you can remember to change the time for next maintenance. This time, the health care is carried out in three times. Considering that the parts must be authentic and maintained by the original factory or OEM manufacturer, the first is the oil and machine filter (maintenance package when buying a car) replaced at the 4s shop, generator belt, gasoline filter, spark plug, brake fluid, rear vibration damping buffer rubber. The second is to change the gearbox oil at a store that it thought was reliable. The third is to buy the rear brake pads (the front pads were replaced at the beginning of the year) and original coolant on a certain website. Because the air filter and air filter were replaced half a year ago, all the things that can be replaced have been replaced together. Okay, let’s go straight to the picture.

This is removed and is exactly the same as the one provided by the 4s.
This is the details of the combustion. It looks okay. Normally, it is Sinopec, half of the highway and half of the city.
This is the front of the engine oil package.
This is the nameplate of the generator belt. It is the same as the one removed. In fact, the old one is good, except that it has been used for a long time.

I found out that the post-buffering glue had aged before. The quality of this was really poor and it had long been broken. I replaced it this time.

Considering the cost and quality, I found a reliable shop outside and changed the gearbox oil by gravity. I think this is the key to this maintenance, because it has been 100,000 kilometers, and the gearbox has been working normally before, and I am afraid that there will be setbacks and other problems after the replacement, so I carefully chose a shop and felt that the decision was correct afterwards.
Let’s drain the old gearbox oil first. It looks quite clean, but it looks quite dirty when you put it down.
