In mid-January 2021, when the vehicle was started in the early morning, the instrument sounded with a “ding” sound and the “wrench” flashed, which meant that the ninth maintenance period of our Hailang was over.
According to my car habit, I have to maintain it every 5000 kilometers, but this time the maintenance plan was nearly 400 kilometers longer than I originally planned before I took Hei Lang to maintain it. I was really busy at the end of the year.
Bringing Hei Lang into the store for maintenance can be said to be a belated maintenance job. At this time, there are not many vehicles entering the store, and there are a few scattered vehicles.
The new Lavida plus next to our Black Langbi is not inferior in appearance.
The staff opened a workshop in Hailang for maintenance, and the master immediately greeted him.
The benefits of making an appointment in advance are vividly reflected at this time. The store has already prepared the materials for this maintenance and replacement, 5W-30 fully synthetic engine oil and oil filter elements.
While I was still taking photos of the engine oil, the master had already started maintenance work. The picture above was removing the screws on the air filter housing.
In the early stage, I replaced the air and air conditioning filter elements myself, and this maintenance only requires cleaning.
After cleaning the filter element, check other oils and pipe connections in the engine compartment, lift the vehicle for the next maintenance operation
At first, I didn’t think there were many cars in the workshop, but later I discovered that all the lift shelves in the workshop were full.
Hei Lang has risen into the sky and the lower engine guard has been removed.
Waste oil is being discharged.
I use Harvest Multipolar 5W-30 fully synthetic engine oil. This maintenance time is less than half a year since the last maintenance time, and I have run 5400 kilometers, but the oil released is black. I personally think that although I use fully synthetic engine oil, it is still necessary to do maintenance every 5000 kilometers.
Regarding the filling of tire pressure.
Regarding the filling of tire pressure, there is a problem point here. I would like to consult with you.
Which do you think is more accurate when the vehicle is landing and when the vehicle is rising?
I personally think it is more accurate to measure the air pressure when the vehicle is rising, because the tires at this time do not have any load. (In fact, this habit is more critical.)
The tire has been in use for nearly 4 years since the purchase of the car, and fine cracks have appeared on both sides of the tire. It is normal for the rubber material to age. Prepare to change tires this year.
Some cracks also appeared on the front of the tire, but it was still some distance away from the safety line of the tire. I expect to attack tires in the second half of the year.
After checking the chassis, the next step is to install new machine filters and oil drain screws
Next install the lower engine guard.
Fill the vehicle with new engine oil on the ground, and only use 4L of EA211 engine oil.
After the oil is filled, wait 30 seconds, then start the vehicle to allow the oil to fully lubricate the entire body.
The computer tested Hei Lang’s circuit system and found that everything was normal.
At this point, the entire maintenance is coming to an end, and the engine oil level is checked when the engine is turned off.
The cover fell off and the entire maintenance ended.
This maintenance cost is 151 after 216% off working hours, 448 for engine oil, and 44 for machine filter, totaling 643 yuan.
In fact, the significance of maintenance is not just to change the oil. The most important thing is to find problems during the maintenance process and solve them in a timely manner.
Only by careful care can we provide us with better services.
