What are the items for vehicle secondary maintenance?
4 Answers
Automobile secondary maintenance includes the following items: 1. Engine: The secondary maintenance requires checking the engine's idle, medium-speed, and high-speed operation conditions, as well as whether the cylinder pressure and vacuum degree meet the standards. It also involves verifying if the engine's various indicators after the three-clean and three-filter operations comply with specifications. 2. Clutch: This item involves testing the convenience, smoothness, and reliability of clutch operation to ensure the clutch is easy to use, free of abnormalities, and that the hydraulic system has no oil leaks. 3. Tires: Check whether the tire pressure is normal, whether there are debris such as small stones in the tire tread that could damage the tires, and whether there are signs of aging or bulging in the tires. 4. Whole vehicle inspection: This item involves checking the overall condition of the vehicle, such as cracks in the frame, loose screws, the functioning of lighting, and any abnormal noises while driving. If any issues are found, they will be immediately inspected, adjusted, and resolved.
Last year when I performed the secondary maintenance on my car, I found it included several key items. I changed the engine oil and oil filter myself to ensure smooth engine operation; checked the brake system, inspecting the thickness of the brake pads and the condition of the brake fluid to prevent failure in emergencies; also rotated the tire positions to reduce uneven wear; cleaned the air filter and cabin air filter to maintain fresh air inside the car; finally, tested all the lights and battery health. These steps helped reduce car breakdowns, saving both money and hassle. Secondary maintenance is best done every 20,000 kilometers to identify potential issues early, such as loose suspension or aging belts, preventing breakdowns on the road. The whole process takes some time, but it's worth it compared to the cost of major repairs.
As a long-time car owner, I always emphasize the importance of secondary maintenance items. For example, changing the engine oil and filters is fundamental to maintaining engine longevity; inspecting the braking system, including brake discs and hydraulic systems, ensures responsive performance; the suspension system requires testing the condition of shock absorbers and springs to avoid damage on bumpy roads; checking the steering mechanism for looseness or abnormal noises is also crucial. It also involves adjusting tire pressure and inspecting tread patterns to prevent blowout risks. After each maintenance session, I feel the car becomes more stable, significantly improving driving safety and potentially extending the vehicle's lifespan by several years. Don't overlook electrical components like lighting and battery tests to prevent nighttime accidents. Remember to schedule appointments with reliable shops, as reasonable costs can save you from future troubles.
After having children, I pay special attention to the safety items during secondary maintenance. It mainly includes changing the engine oil to ensure engine cleanliness, checking the brake pads to avoid failure, inspecting and inflating tires to ensure grip, and verifying the functionality of seatbelt buckles; disinfecting the air conditioning system and replacing filters to maintain healthy air inside the car; testing coolant and transmission fluid levels to prevent overheating. This way, I feel at ease driving my kids to school, reducing anxiety about breakdowns midway. After maintenance, the car becomes more comfortable and quieter, also saving fuel and money—killing multiple birds with one stone.
