?? In my impression, my car maintenance is usually before the mileage is up (one year or 10,000 kilometers), but this time Kodiak is up before the mileage is up. After testing it with an oil filter paper, the black diamond oil that was maintained and replaced last time performed well, and it remained fine until September to a year. Considering that the burden of using cars at high temperatures in summer is still very high, there is no need to save time so much, so I took advantage of the weekend to come to the 4S store for secondary maintenance. Secondary maintenance is just a minor maintenance, replacing the oil filter, air filter, and air conditioner filter. The after-sales services of the 4S store are already familiar with, and they drive directly to the workstation to wait for the materials to start work.
???? For nearly a year, Kodiak traveled widely, and he liked it more and more. How to describe it? It seems appropriate to move like a rabbit and be as quiet as a virgin. Many people who have ridden in my car say that this car is good and very cost-effective. Although there are some minor problems of one kind or another that may bother you a little, the shortcomings do not obscure the shortcomings and are worthy of recognition.
Enter the workstation and put on a skirt to protect it.
Lift the car up and remove the engine guard. In order to keep the chassis flat, the original guard plate has no oil drain port and must be disassembled every time it is maintained.
A new engine bottom is protected. I don’t think there’s any need to argue about whether to install a guard. The fact lies here.
This is the engine steel guard plate with the original accessory. The overall workmanship is excellent and the protection is in place. It is worth having.
Remove the guard plate and start draining the oil. Judging from the color, it is not very dirty. Eye observation does not explain the problem, follow-up filter paper testing is the king.
In order to keep the old engine oil cleaner, the maintenance team innovated the process and connected a hose to continue pumping when gravity stopped dripping.
Take advantage of the time to drain oil and turn around the car. This is an original accessory for the rear wheel fender. The original car contour is designed with a mold opening and is installed tightly.
The focus of this maintenance: black diamond fully synthetic engine oil. Similar engine oil on the market is Shell’s extremely clean Heineken. I didn’t expect the 10,000-kilometer black diamond to perform so well. It was indeed a bit unexpected.
Characteristics of this oil. It is highly recommended for turbocharged car owners to use it.
After standing for 24 hours, the oil test filter paper behaves as shown in the figure, and at the same time it smells without irritating smell.
Change the air filter element after changing the oil.
The performance of the air filter element for a year and a half is okay, not very dirty. Maintain it once a year and change it whenever necessary.
The removed air conditioning filter element did not feel very dirty, but in fact, it could no longer be used.
Without comparison, there will be no harm. The old and new filter elements are put together, and the high and low are visible.
Continue to replace the original PM2.5 high-efficiency filter element. Anyone who uses this filter element knows that the filtering effect is quite good. Many car owners have evaluation experiences, so I won’t talk much about them.
Activated carbon side.
All manual work is over, and the computer checks it out. Everything is normal and working. Wan Shiqing’s team leader, who recommended me to maintain this time, is serious, responsible, proactive and highly skilled.
The big brown bear is lively again and will work for another spring, summer, autumn and winter. Let us move forward happily together.
