December is coming! May all the good things come as scheduled, have what you like, and let go of what you lose. Look forward to December can bring your sunshine and smile, work hard for happiness, live for yourself, may all the sweat have a harvest, all efforts will not be disappointed. Talk less gossip, talk about the topic of this issue: what maintenance does the 2018 Qichen T70 20, 000 km need to do?
Subject matter: I haven’t contacted my good friend Brother long for seven months. Recently, I chatted with him on the phone for a while. Everyone in Qichen will definitely talk about car use and car ownership. When he said that his car Xiao Qi now has more than 22000 kilometers, I looked through the previous records, didn’t it already exceed the maintenance mileage? The last maintenance was 10500 kilometers, and now he has run 12000 kilometers, so I asked him to find a time to do maintenance, and I can also send an assignment to share with you.
Open the lid and it’s all dusty.
The average fuel consumption is 8.9 liters and 100 kilometers. How much is your car’s fuel consumption? This maintenance mileage is indeed over, want to love the car is healthier or regular maintenance is better.
Maybe the road is not good.
Pour into a bottle of engine internal cleaning agent to clean.
When we idle for 15 minutes, we can check the air box ourselves, and the air box has two buckles, which are broken by hand, which is very simple.
The air compartment is used to filter the air into the engine, if there is too much dust or there is a foreign body blocking, it will affect the air intake and cause an increase in fuel consumption. at the same time, if the poor quality air compartment can not filter the fine dust into the engine, it will pollute the engine oil and shorten the service life of the oil.
It is recommended to replace 20,000 kilometers, or every other maintenance.
Compare the new air with the old air.
It is easy to install, and it is not difficult to do it yourself.
My air compartment is a general brand, as long as the quality is not too bad.
Just put it in there.
After changing the air frame, turn off the engine and raise the chassis.
In order to avoid oil pollution, the lower guard plate should be removed.
Find the engine oil drain screw.
Release waste oil, this is the oil after running 12000 kilometers with cleaning agent, as long as there is no shortage of oil, it is not a big problem.
Take advantage of this oil gap to check the tire pressure, the standard is 2.4.
Take a look at the rear chassis.
No abnormality is found after checking the chassis, the waste oil has been put out, tighten the oil release screw and replace the new oil compartment.
This time, we use Nissan imported iron can full synthetic engine oil, and the maintenance mileage is 10,000 km once.
When the engine compartment is clean, first blow the dust off the surface of the engine compartment with an air gun.
Don’t rinse with water.
Spray with engine compartment foam cleaner and wait for a while before wiping it with a wet cloth.
The most important thing is to check the liquid level of the oil ruler after changing the new oil. The 2018 T702.0 engine with 4 liters of oil is just enough.
Nissan and Qichen air conditioning box is more difficult to disassemble and install, generally do not recommend Xiaobai do it yourself, easy to break the card buckle, of course, 4S store to replace the air conditioner box is also charged 30 yuan man-hours.
Find the location of the air conditioner under the co-pilot’s armbox.
It takes a lot of time to disassemble and disassemble the air conditioner grid, but you can see that the design position of Nissan and Qichen air conditioner grid is very unreasonable, so this is the reason why I suggest changing the air conditioner grid every time I disassemble and disassemble it.
Comparison of new and old air conditioners.
You’d better wait for the repairman to install it.
What kind of instrument is this?
After changing the air conditioner, there is an in-car atomization disinfection. I heard that the scene was very shocking.
The atomization instrument gives off a lot of smoke when the medicine is heated.
It can be understood as similar to the antivirus effect of ozone.
The regular maintenance operation time is about 40 minutes. Of course, I didn’t take pictures of some inspection items, such as checking brake oil, checking antifreeze, checking batteries, checking brake pads, etc., although these are all suggested replacement cycles, but each maintenance requires attention and inspection is an essential process.
Summary: this 20,000km maintenance project (the actual kilometer of the instrument is 22531KM) has to change the oil compartment, air compartment and air conditioner compartment of the engine. The next maintenance suggestion is to check whether the throttle has carbon deposit before deciding cleaning / four-wheel cross-adjustment / four-wheel dynamic balance / four-wheel positioning. This is the end of the 2018 Qichen T70 20000 km maintenance operation sharing. Thank you for your support. See you in the next assignment.
