Six steps of scientific maintenance of new car maintenance knowledge

You need to recognize: the difference between maintenance and repair

First of all, maintenance and repair measures are different. Maintenance focuses on planning and prevention, and mandatory operations are usually taken. Repairs are operations that are carried out as planned and needed. In addition, the purpose of the two is different.Maintenance is usually to reduce the wear rate of parts, prevent failures, and prolongcarService life; while repairing usually repairs the parts that have failed or lost the ability to work, restore the car's good technical condition, working ability, and extend the service life.

There is maintenance during repair and repair during maintenance. Insist on focusing on maintenance, and overcome the bad tendency of "repairing and neglecting insurance" and "repairing for insurance". "Three-point cultivation and seven-point cultivation" is the truth.

Eight major inspections and replacements for the first maintenance of a new car

1. Change the oil,Oil filter,gasolineFilter,air filter.

2. Check whether the position of the car coolant level is in a normal state.

3. CheckBrakeandclutchLiquid level position.

4. Check whether the oil level of the power steering oil tank meets the regulations, and check whether there is oil leakage at the oil pipe connections of the system.

5. Check the battery liquid level and glassdetergentThe liquid level of the tank.

6. CheckDynamo,air conditioner,Water pumpandBooster pumpbeltTightness and aging.

7. Check whether the front and rear lights of the car are working properly.

8. Check the cartireAir pressure and wear conditions, tighten according to the specified torquetireThe screw and tire pressure shall be added to the specified value of the model, and the tire shall be rotated according to the wear condition.

The inspection items listed above are the basic inspection items for the vehicle, and the procedures should be done according to the items during the first warranty; you can follow the vehicle maintenance throughout the entire process, but you need to pay special attention to: whether to use the first warranty engine oil issued by the original factory, and the first replacement engine oil The quality must be passed to avoid damage to the engine; the replacement of the filter is also important to prevent the occurrence of unreplaced situations.

Second encounter with 4S due to maintenance

1. Check that the engine should be easy to start, run smoothly, exhaust gas is normal, water temperature, and oil pressure meet the requirements after passing the three-clean and three-filter operation.Rotating speedStable, no abnormal noise, moderate tension of the belts, no leakage of water, oil, electricity, or gas.

2. Check that the direction free stroke and toe are in line with the requirements, the steering is light, flexible, and reliable, and the front wheels are free from left and right head swings and deviations when driving.

3. Check that the free stroke of the clutch meets the requirements, the operation is convenient, the separation is thorough, the combination is stable and reliable, there is no abnormal noise, and there is no oil leakage in the hydraulic system.

4. Check the gearbox,Drive axle,orHalf shaftThe transmission device has good lubrication, reliable connection, no abnormal noise and overheating, no shifting, flexible shifting, and no oil leakage.

5. CheckBrake pedalThe free stroke and brake intermittently meet the requirements, the driving and parking brakes are good, there is no deviation and drag during braking, and the inertial proportional valve works normally and does not leak oil.

6. Check that the tire pressure is normal.

7. Check that the cantilever and shock absorption are fixed and reliable, and their functions are normal.Wheel hubThe bearing temperature is not high after driving.

8. Check the generator,starter, Lights, meters, lights, buttons,switchThe accessory is well-equipped, complete, and can work normally.
