What Does Vehicle Level 1, Level 2, and Level 3 Maintenance Mean?
2 Answers
Introduction to the meaning of vehicle level 1, level 2, and level 3 maintenance: 1. Level 1 maintenance: Tightening of various assemblies and connecting parts, lubrication of main assemblies and components, and some necessary adjustment operations found during external inspections. It is generally performed when the vehicle has traveled 1,500~2,000 km. The main tasks include: inspecting and tightening loose bolts and nuts on the exterior of the vehicle, applying grease to lubrication points as specified in the lubrication chart, adding lubricating oil to various assemblies, and cleaning all filters. 2. Level 2 maintenance: In addition to the tasks of level 1 maintenance, the focus is on inspection and adjustment, including tire removal and rotation. It is generally performed when the vehicle has traveled 6,000~8,000 km. 3. Level 3 maintenance: This is second only to a major vehicle overhaul, focusing on disassembling assemblies, cleaning, inspecting, adjusting, and eliminating potential hazards. The maintenance cycle for level 3 is generally 36,000~40,000 km.
I remember driving for many years, and the vehicle maintenance divided into Level 1, Level 2, and Level 3 is quite practical. Level 1 maintenance is the most basic, like a minor service for the car, usually done every six months or around 5,000 kilometers. It mainly involves checking basic items such as engine oil, coolant, and tire pressure to ensure the car can start and run normally. Level 2 maintenance is a bit more involved, checking brake pads, filters, and replacing spark plugs if necessary to prevent minor issues from becoming serious. Level 3 maintenance is a comprehensive inspection, including deeper checks on the transmission and cooling system, and may involve replacing critical components like the timing belt. The key is not to skimp on a few hundred bucks—regular maintenance can save you tens of thousands in major repairs later and avoid breakdowns on the road, ensuring safety. I always follow the car manual, and forming this habit is totally worth it.
