GL8 ES Maintenance Guide Common Problems Case Summary (Collectible)
BeacherNehemiah 
11 I haven’t written a post for a long time. Today, I make a summary on the cases of GL8 ES maintenance and common diseases, hoping to provide help to the new and old cyclists in the altar.
First of all, let me talk about how I feel about this car.
Fuel consumption:
Urban fuel consumption: 10: 11 long distance: 8: 9 such a big car, fuel consumption is still very satisfactory. Everyone should change the impression of Buick gas guzzler.
Failure rate
The failure rate of the GL8 ES is not high, and it has changed the fate of common gearbox problems. It’s really a lot easier than BBA.
Space
Whether for business or household use is enough, the first choice for second-child families, the absolute first choice. Seven people don’t feel nervous at all, and they can pull a few suitcases at the same time.
Driving performance
Driving a GL8 ES is like driving a small car. It doesn’t feel like driving a big MPV, and the line of sight is very good. 2.0T engine acceleration overtaking, lane change is very easy, the most important thing is that the long distance driving for several hours in a row will not feel tired.

Seven points of maintenance, three points of maintenance.
Cars and people, only good maintenance will play a good state, of course, can not be excessive.
Give some advice on maintenance based on my repair experience
Oil + filter (using fully synthetic oil) is changed every 8000 km
Air filter, according to air quality, maintenance and replacement every time or every two times
Gas filter, and gasoline pump are one, do not need to be replaced, but pay attention to refueling, add inferior gasoline caused by gas filter blockage, it is necessary to replace the gasoline pump assembly.
Air conditioning filter, it is recommended to replace it twice a year.
Gearbox oil is recommended to be replaced every 4W km
Brake oil, it is recommended to change it every two years
Booster oil, because it is an electronic steering machine, does not need to be replaced.
Spark plug, it is recommended to replace every 6W km
The throttle is recommended to be cleaned every 3W km.
It is recommended to clean the combustion chamber every 6W km.
It is recommended to change the tire every 8W km.

Oil is as important to the engine as blood is to the heart. The oil contains many kinds of additives to ensure the normal operation of the engine.
The oil has the functions of lubrication, cleaning, rust prevention, sealing and cooling. Too long time period or too many kilometers will lead to the attenuation of oil function, so it is necessary to change the engine filter regularly in order to ensure the normal operation of the engine.

It is recommended to change every 8000 km when GL8 ES uses full synthetic engine oil.
According to the working temperature and design structure of the engine, the working condition and performance of the engine with 5W-30 synthetic oil will be better.
Capacity for changing oil: 4.5 litres
The function of the air filter element is to filter the dirt in the air needed by the engine to reduce the wear and tear of cylinders, pistons, piston rings and valves.
The damage caused by the impurities in the intake to the engine is far more serious than the impurities in the oil, so the air filter should be replaced regularly.

The air filtration of GL8 ES is recommended to be checked every maintenance cycle. Cities with good air quality can be maintained and replaced every two times, and cities with poor air quality are recommended to be replaced every time.
The function of the air conditioning filter element is to filter the air into the air conditioning system and indoor.
Air conditioning filter element used for a long time the impurities in the air will be adsorbed on the filter element, a long time will cause the air outlet air weakening. In addition, in the damp and dark environment, the air conditioning filter element will also breed bacteria, resulting in air conditioning odor. There is also activated carbon in the air conditioning filter element, and the adsorption function of activated carbon will also decrease for a long time. All air conditioner filter elements need to be replaced regularly.

The filter element of GL8 ES air conditioner is recommended to be replaced twice a year.
Now many aspects of the car are in the pursuit of maintenance-free, I do not know whether it is saved or wasted.
GL8 ES’s gasoline filter element and gasoline pump are integrated and cannot be replaced alone. So refueling is particularly critical. I have met several riders who have replaced the fuel pump. It is not that the fuel pump is broken, but that the bad fuel leads to the blockage of the gasoline filter, the decline of engine power and the difficulty of increasing speed.

Gearbox oil, like the blood of a gearbox, has the functions of transmission, lubrication, cleaning and cooling.
The gearbox oil works in the torque converter to transfer engine torque to the gearbox. Make the shift actuator correctly perform the shift action under the action of hydraulic pressure.
Lubricate the planetary gear and the shift friction plate.
Iron filings, coking and other impurities are recycled, and filtered and adsorbed through the gearbox filter element and the magnets in the gearbox.
The gearbox oil circulates to cool the gearbox to prevent high temperature in the gearbox.

The gearbox oil is oxidized during the service cycle, and the impurities become more and more. Irregular replacement will affect the normal operation of the gearbox and even cause gearbox damage.
GL8 ES gearbox oil is recommended to be replaced every 4W km or two years.
Recommended replacement of circulation machine
The main function of brake oil is to transfer the pressure in the brake, dissipate heat to the high temperature brake pump, as well as anticorrosion and lubrication.
Brake oil has strong water absorption, which will absorb water in the air and lead to a decline in performance. the higher the moisture content, the lower the boiling point. Too high brake temperature at high speed will cause air bubbles in the brake oil and lead to brake performance reduction or failure. So the brake oil should be changed regularly.

Brake oil for all models is recommended to be changed every two years.
No one is perfect, the car is never finished. In fact, all cars have their own common problems. But there are really not many common faults in GL8 ES compared to BBA.
Next, I would like to make a list of the common faults and vulnerabilities of GL8 ES for everyone to pay more attention to when maintaining a car.
(1) Battery
(2) engine claw pad
(3) Brake tubing
(4) hem arm
(5) Top glue of shock absorber
(6) Generator wheel

GL8 ES batteries usually need to be replaced in 1 or 2 years.
Failure phenomenon: start-up does not respond, or the instrument prompt can not detect the key.
The navigator has a black screen when it first starts, and it is normal after landing for a while, which is a sign of battery damage.
The reason for the damage of the GL8 ES battery is not the quality of the battery, but that the start and stop battery of AGM is too close to the engine, and the heat is too high, so it affects the life of the battery.

Generally speaking, many engine pawl pads are damaged when they are more than 4W kilometers. In view of this problem, Shanghai GM subsequently replaced the improved engine claw pad and improved this problem.
Failure phenomenon: in the case of D-gear parking, the steering wheel and seat resonate, and R-gear and D-gear switch has abnormal sound.

This place is broken.
The part number of the improved claw pad
The brake tubing of GL8 ES is easy to bulge, and if it is serious, it will break and cause brake failure, which is especially dangerous at high speed.
Shanghai GM announced a recall of vehicles with brake tubing quality problems on July 31, 2020.
Specifically, you can consult the local maintenance station whether the vehicle brake tubing is within the scope of the recall claim.

The lower swing arm is the support of the tire, an important component of the chassis, and is a vulnerable part. Generally, aging damage will occur when driving more than 12W kilometers.
Fault symptom: There is a squeaking sound when the road is bumpy.
It is recommended to replace the rubber sleeve of the lower hem arm in time after checking for aging and damage

The top glue of the shock absorber of the GL8ES manufactured in 17 years is easily damaged, and the ones shipped later have been improved.
Fault symptom: There is a squeaking noise on bumpy roads.
The problem can be solved by replacing the shock absorber top glue.

The generator wheel generally drives 8.9 W kilometers or hundreds of thousands of kilometers
Abnormal sound occurs
Fault phenomenon: abnormal sound occurs at the moment of flameout or when the load is heavy
In this case, just replace the generator wheel.
