What items are generally included in the second maintenance?
2 Answers
The second maintenance involves eight major areas including the engine, automatic transmission, air conditioning system, steering system, braking system, suspension system, body parts, and tires, totaling up to 63 inspection and maintenance items. In addition, it also includes quality inspection and test driving. Therefore, it is essential to pay attention to the second maintenance of the vehicle. The inspection and maintenance items for the second maintenance of the vehicle are: 1. After the engine undergoes the three-cleaning and three-filtering operations, it should start easily, run stably, have normal exhaust (meaning the exhaust meets standards), meet the requirements for water temperature and oil pressure, maintain stable rotation speed, have no abnormal noises, and all belts should be properly tensioned with no leaks (water, oil, electricity, or gas). 2. The steering free travel and toe-in should meet the requirements, with light, agile, and reliable steering. The front wheels should not wobble left and right or deviate while driving. 3. The clutch free travel should meet the requirements, with convenient operation, complete separation, stable and reliable engagement, no abnormal noises, and no oil leaks in the hydraulic system. 4. The transmission, drive axle, universal joint (or half-shaft) transmission equipment, etc., should be well lubricated, securely connected, with no abnormal noises or overheating, no gear jumping, smooth gear shifting, and no oil leaks. 5. The brake pedal free travel and brake clearance should meet the requirements, with good driving and parking brakes. There should be no deviation or dragging during braking, the inertia proportioning valve should work normally, and there should be no oil leaks. 6. The tire pressure should be normal (different models have different high and low tire pressure standards). 7. The suspension arms and shock absorbers should be securely fixed, perform normally, and the wheel hub bearing temperature should be low after driving. 8. The generator, starter, lights, instruments, signal lights, buttons, switches, and affiliated equipment should be complete and intact, functioning normally. 9. All lubrication points of the vehicle should be filled with lubricating oil. 10. The entire vehicle should be thoroughly cleaned.
I'm relatively new to driving, and after my new car had run about seven or eight thousand kilometers, I took it in for its second maintenance, which felt like giving the car a physical and a blood transfusion. The main tasks were changing the engine oil and oil filter because the impurities inside could affect the engine's lifespan. They also carefully checked the tire pressure and wear condition to ensure there would be no slipping on the road. The braking system underwent a thorough inspection, including the thickness of the brake pads and fluid levels, to prevent any issues in emergencies. If the air filter was dirty, it was replaced with a new one to keep the airflow clean. The mechanic also checked the battery charge and topped up various fluids like coolant and power steering fluid. The whole process took about an hour, but the cost was reasonable. Developing good maintenance habits makes driving more reassuring and fuel-efficient.
