What is the difference between major maintenance and minor maintenance?
1 Answers
Major car maintenance involves more items and is performed at higher mileage compared to minor maintenance. Here are the specific differences between the two: 1. Minor car maintenance, typically done every 5,000 kilometers or 6 months, mainly includes changing the engine oil and oil filter. Minor maintenance involves fewer replacements and focuses on basic checks and adjustments. It usually includes changing the oil, checking and adjusting tire pressure, inspecting and tightening chassis screws, checking and cleaning the air filter and cabin air filter (replacing if necessary), inspecting lights, and other routine checks. Minor maintenance is generally required every 5,000 kilometers and primarily involves inspections and necessary part replacements. 2. Major car maintenance is usually performed after 50,000 kilometers. Before 50,000 kilometers, most checks are inspection-based. The aging of car fluids, rubber components, and other parts is cyclical (excluding collision damage). Major maintenance includes cleaning engine carbon deposits, replacing brake fluid, replacing transmission fluid, replacing coolant, replacing windshield wipers, inspecting chassis rubber components (replacing if necessary), checking brake pads (replacing if necessary), inspecting tire tread depth and aging (replacing if necessary), checking wheel alignment data, cleaning the sunroof (to prevent drainage blockage), cleaning the air conditioning evaporator and air ducts, and replacing the fuel filter (external fuel filters are replaced every 20,000 kilometers, while internal fuel filters are replaced every 50,000 kilometers).
