In mid-January 2021, when the car started in the early morning, with the instrument “ding” sound, “wrench” flashed, which means that our black Lang’s ninth warranty period has arrived.
Coincides with the end of the year, things are relatively busy, has been put off until the 29th of the twelfth lunar month (also the last working day at the end of the year), just have time to bring black Lang into the store for maintenance.
According to my habit of using the car, it is necessary to maintain the 5000km once, but this time the maintenance plan is higher than my original plan. I just brought black Lang to the maintenance near 400km. I was really too busy at the end of the year.
December 29, that is, February 10, rushed into the store with Hailang for maintenance before the end of the year, which is a belated maintenance operation. At this time, there are not many cars entering the store, scattered several cars.
Our black long is no less handsome than the new Langyi plus next to us.
On the last working day before the end of the year, the staff who could see the shop were anxious (my heart was actually very anxious and embarrassed), and the staff hastened to maintain the black room workshop, which was immediately welcomed by the master.
The benefits of booking in advance are reflected incisively and vividly at this time. The store has already prepared the maintenance and replacement materials for Heilang, 5W-30 fully synthetic oil and oil filter element.
When I was still taking oil photos, the master had already started the maintenance operation, and the above picture was removing the screws of the air filter shell.
In the early stage, I have replaced the air and air-conditioning filter element, this maintenance only needs to be cleaned.
After cleaning the filter element and checking other oil and pipe joints in the engine compartment, lift the vehicle for the next step of maintenance.
At first, I didn’t feel that there were many cars in the workshop, but then I found that the hoist shelves in the workshop were full. It seems that many riders, like me, are in a hurry to take good care of their cars before the end of the year, so that they can rest assured to use them during the Spring Festival.
Heilang has lifted off and the lower guard of the engine has been removed.
Waste oil is being discharged.
I use Castrol multi-pole protection 5W-30 full synthetic oil, this maintenance time less than half a year from the last maintenance time, ran 5400km, but the oil released I feel is black. Personally, I think it is necessary to use all-synthetic engine oil, but it is necessary for 5000km to do a maintenance.
With regard to the filling of tire pressure, here is a problem, please consult everyone.
Which do you think is more accurate when the vehicle lands or when the vehicle rises, filling the air pressure and measuring it?
Personally, I think it is more accurate to measure the air pressure when the vehicle rises, because there is no load on the tires at this time. (in fact, this habit is rather critical.)
Since buying a car, the tire has been used for nearly 4 years, there are slight cracks on both sides of the tire, and the aging of rubber material is also normal. I’m going to change the tire this year.
There are also some cracks on the front of the tire, but there is still some distance from the safety line of the tire. I’m expected to hit the tires in the second half of the year.
After checking the chassis part, it is followed by the new machine filter and oil discharge screw.
Then install the lower guard of the engine.
New oil is added to the vehicle when landing, and 4L oil of EA211 engine can be used.
After the oil is filled, wait 30 seconds, then start the vehicle and let the oil be fully lubricated to the whole body.
The computer detects the Heilang circuit system and everything is normal.
At this point, the whole maintenance is coming to an end, and the oil level is tested by flameout.
The cover of the machine falls, and the whole maintenance is over.
The maintenance cost is 216 hours after 151, oil 448, machine filter 44, the total cost is 643 yuan.
In fact, the significance of maintenance is not just to change the oil, the most important thing is to find problems in the maintenance process and solve them in time.
Careful care can provide us with better appearance service.
