Dahei 100,000-kilometer maintenance operation

September 5, 2024

After this maintenance, all the maintenance that should be done within 100000 kilometers has been done. At 70, 000 kilometers, the whole car’s oil has been changed (brake oil, transmission oil, antifreeze fluid) the throttle has also been removed and the oil road has been cleaned. At 80, 000 kilometers, 4 Michelin tires have been changed, basically in accordance with the long-term driving pace to maintain.

Has been 4S store maintenance, since the first insurance has been using gray shell 5W30 oil, each time about 9500 to maintenance.

I made an appointment and arrived at the store early in the morning. I wanted to go early and come back early.

Come a little early, , the staff in the store are not at work.

This maintenance project: changing oil, air conditioning filter element, air filter element, cleaning ternary catalysis, cleaning intake carbon deposition

The master first used the computer to check the condition of the car.

A dark filter orifice

Still use the gray shell of this oil 5W30, 5.5L at a time.

The cabin, which is nearly 100000 kilometers, is clean.

The raised chassis is also very clean.

The oil on the 9500KM is swarthy.

When the oil is free, the master replenishes the tire pressure and checks the stones on the tire and so on.

This is the oil filter element used this time. I can’t tell which one produced it.

5.5L is added without a drop, just reaching the upper limit.

I usually change the air filter element once a year, usually do not take it out to blow, I feel that blowing will destroy the filter. This time I originally planned to use a 25% discount coupon, , you can’t have both fish and bear’s paw, 88 yuan coupon and it can’t be used at the same time, you can only pay 135 yuan to buy it, and the man-hour fee is waived.

The air conditioner filter element, which is 20,000 kilometers a year, does not feel very dirty, but it still chooses to be replaced.

It uses the air conditioner filter element bought with 75% discount coupons at the end of December and has been using this PM2.5 filter element. It’s just right to change once a year.

Despite the fact that it is not dirty on the surface, it is very dirty on the inside.

This is the interior of the air filter element for one year, and it is still very dirty.

The oil filter element is changed once, and the basic 9500KM is changed once or so. Unlike air conditioner filter element and air filter element, it must be changed every time.

Last time I bought the maintenance package sent the intake carbon cleaning, just at the beginning of the Lunar New year valve dismantled and washed, the oil road is also cleaned just to use the coupons this time, by the way 300 yuan to a three-yuan cleaning.

This is the machine to carry out ternary cleaning, which is the kind of detachable cleaning.

Ternary cleaning reducing agent, worth 300 yuan a bottle

The oxygen sensor needs to be removed.

Input the machine tube into the cleaning agent through the oxygen sensor mounting hole

Pour in the detergent and start directly. it will take about half an hour to clean twice.

There is a waste pipe at the tail to protect the environment.

The carbon deposition cleaning of intake air is cleaned with this machine.

The intake pipe needs to be taken apart, and the pipe of the cleaning machine can be inserted directly.

It is also washed twice, about half an hour.

Fortunately, the workshop was the first to arrive at the end of the year, and the workshop has begun to queue up and squeeze a lot of maintenance cars.

After cleaning, the exhaust pipe began to spray water.

Four-wheel positioning I feel that the personal experience is still reliable in the 4S store, before the outside tire change spent 100 yuan to do positioning, clearly showed by the deviation, but the store said no problem, no need to adjust. Has been thumping for a long time, this time happens to have a positioning coupon to experience the four-wheel positioning of the 4S store.

4S store special four-wheel positioning shelf, equipment protection is also very in place, I found that after using up, the master will turn off the equipment to protect the equipment.

Put it on the shelf and wait for the big black of four rounds of positioning.

50% means that only 2 positioning sensors have been installed, and the interface will be displayed after installation.

When the sensor is installed, the master begins to move the vehicle back and forth to make the sensor receive the data.

The master began to adjust the chassis according to the data displayed by the machine. The master said there was no big problem. The chassis was fine. Just adjust it a little bit.

The operation completed this maintenance is also counted as a settlement, this time unexpectedly began to have this checklist, clear and refreshing.
