If there is no problem with the car itself, there is no need to deliberately replace it. It is just routine maintenance. The specific maintenance plan is determined based on the number of kilometers the car has run, the maintenance personnel's suggestions and the wear and tear of the parts on the car.
Maintenance precautions:
1. The gasoline filter element and air filter element should be replaced every 10,000 kilometers.
The air conditioning filter element should be replaced every year or 2 Replace it after about 10,000 kilometers.
2. The entire vehicle oil needs to be replaced at 40,000 kilometers.
3. The gearbox must be inspected during each maintenance. Although there is no need to replace the oil, the amount of gearbox oil must be checked regularly, and non-original oil must not be replaced without permission.
4. Check the spark plugs every 40,000 kilometers and replace them every 80,000 kilometers.
Suggested inspection items:
1. Check whether the car coolant level meets the regulations.
2. Check the brake fluid, the working condition of the brake system, and whether there is any oil leakage.
3. Check whether the oil level in the power steering oil tank meets the regulations.
4. Check the battery fluid level and glass cleaner fluid level.
5. Check whether the generator, air conditioning system, etc. are working properly.
6. Check whether the steering is light, flexible and reliable, and whether the front wheel swings left or right while driving.
7. Check the working condition of the lights and horns, and whether the front and rear lights of the vehicle are complete (including headlights, width lights, turn signals, brake lights, reversing lights and fog lights).
8. Check the tire pressure and wear of the car, and replace the tires according to the wear.
9. Check the battery status.
10. Check the working status of the engine, whether it is easy to start, runs smoothly, the exhaust is normal (meaning the exhaust gas meets the standard), the water temperature and oil pressure meet the requirements, the speed is stable, and there is no abnormal noise.
11. Check whether the chassis and steering mechanism are flexible, the bolts are tightened, and the pipe joints and tee pipe threads should be intact, tightly coupled, and airtight.
12. Check whether all relevant parts of the vehicle need lubrication.
When the speed of Fengjun 5 suddenly increased to more than 2,000, there was a whistle.
The reason why the instrument light of Fengjun 5 does not light up is that the instrument assembly is damaged or If the instrument light fuse is burned out, just replace the accessories. The instrument is a display screen that displays vehicle-related information. If a fault occurs, the driver will not be able to understand the vehicle's information in a timely manner. When the fault occurs, timely inspection and repair are required. The following is the relevant content of instrument lights: 1. Indicator lights: The most common indicator lights when driving, such as light signals, turn signals, parking lights, etc., are used to indicate the status of various functions of the vehicle; 2. Warning lights: have warning functions For example, fuel indicator light, door status indicator light, seat belt indicator light, etc. Generally, the warning light goes out after the driver takes corresponding actions. For example, the seat belt indicator light turns off when we fasten the seat belt.will go out; 3. Fault indicator light: It is also the most important indicator light, such as: generator fault indicator light, gearbox fault indicator light, etc. These malfunction indicator lights rarely light up at ordinary times, or they light up for a moment and then go out when the engine is started. If the malfunction indicator light is always on and accompanied by a warning sound, it indicates that the vehicle has malfunctioned or is abnormal.
There are two fundamental reasons for the loud engine noise: excessive carbon deposits in the engine. The engine oil is inappropriate or the oil is dirty.
In addition, most of the engine noise is caused by abnormal engine noise:
1. Engine lower protection Board screws are loose. A relatively common minor fault is tightening or adjusting the engine lower guard plate screws.
2. The engine claw pads are aging. The claw pads play a role in supporting the engine and can only be replaced after aging.
3. The plastic parts in the engine compartment are loose. For example, the engine cover, air intake pipe, etc. can be tightened.
4. The engine belt makes abnormal noise. Including power belts, generator belts, etc. If the belt is old or is too loose or too tight, it will produce abnormal noise. Replace or adjust the tightness.
5. Engine knocking. There is too much carbon deposit inside the engine or the fuel usage is substandard. Clean carbon deposits and replace fuel.
6. Abnormal valve noise. Especially after the car is cold, the valve will make a "click-click" sound, and then it will be fine when the car is warmed up. This is because the engine oil is deposited in the oil pan and is not "pressed" in time when the engine is started. But if the valve keeps ringing, you should consider changing to a thicker engine oil (for how to choose engine oil, please refer to "How to Choose the Engine Oil Correctly").
7. Engine "backfire" failure. The engine will make a "puff-puff" sound, which may be caused by excessive carbon deposits on the valves or improper timing adjustment. Clean the carbon deposits on the valves and adjust the valve timing.
8. The engine is missing a cylinder. If a certain cylinder does not ignite, most likely the spark plug or ignition module is faulty and can be replaced.
9. Abnormal noise from the bearing. There will be regular "buzzing" sounds in bearings, such as engine tensioners, idlers, generators, etc. This can be solved by replacing relevant parts.
