First, the first-class maintenance and inspection items of automobiles.
1. Replace the oil, oil filter, gasoline filter and air filter.
2. Check whether the liquid level position of automobile coolant meets the requirements.
3. Check the liquid level position of the brake and clutch.
4. Check whether the oil level of the power steering oil tank meets the requirements, and check whether the oil pipe interfaces of the system leak oil.
5. Check the liquid level of battery and glass cleaning tank.
6, check the generator, air conditioning, water pump and booster pump belt tightness and aging.
7. Check whether the front and rear lights of the car are complete (including headlights, width lights, turn signals, brake lights, backup lights and fog lights).
8, check the automobile tire pressure and wear, tighten the tire screws according to the specified torque, add the tire pressure to the specified model value, according to the tire wear transposition.
9, check whether the automobile exhaust emission standards.
Second, the vehicle secondary maintenance inspection items.
1. The engine should be easy to start, run smoothly, exhaust normally (refers to the exhaust gas reaching the standard), the water temperature and oil pressure meet the requirements, the speed is stable, there is no abnormal sound, the belt is moderately tight, and there are no four leaks (water, oil, electricity and gas).
2. The directional free travel and toe-in meet the requirements, and the steering is light, flexible and reliable. When driving, the front wheel has no left-right swing and deviation.
3. The free stroke of the clutch meets the requirements, with convenient operation, complete separation, stable and reliable combination, no abnormal sound and no oil leakage in the hydraulic system.
4. Gearbox, drive axle, universal joint (or half shaft) transmission device, etc. Good lubrication, reliable connection, no abnormal sound and overheating, no tripping, flexible gear shifting and no oil leakage.
5. The free travel and intermittent braking of the brake pedal meet the requirements, the driving and parking braking are good, there is no deviation and delay during braking, the inertia proportional valve works normally and there is no oil leakage.
6. The tire pressure is normal (different models have different high and low air pressure standards).
7. Cantilever and shock absorber are fixed reliably and function normally, and the temperature of hub bearing is not too high after driving.
8. The generators, starters, signal lights, meters, signal lights, buttons, switches and ancillary equipment are complete and can work normally.
9. Fill all lubricating points of the vehicle with lubricating oil.
