How many kilometers should a major maintenance be performed?
3 Answers
Generally, a major maintenance is performed every 40,000 kilometers. However, this interval is not absolutely fixed, as some vehicle models may require it every 60,000 kilometers. The specific schedule should follow the maintenance manual (vehicle user manual) which provides detailed instructions. Additional information: 1. Major maintenance replacement items: Major maintenance builds upon minor maintenance. Routine minor maintenance only requires oil and oil filter replacement, while major maintenance involves more items. In addition to oil and oil filter, major maintenance typically includes the following: (1) Replace air filter, cabin air filter, and fuel filter. (2) Replace transmission fluid. (3) Replace brake fluid. (4) Replace coolant. (5) Replace spark plugs. 2. Major maintenance inspection items: Additionally, tires and brake pads require special attention. If severe wear is detected, immediate replacement is necessary. The replacement intervals for these components vary significantly due to various objective factors, but generally fall within the range of 40,000 to 60,000 kilometers. Another critical component is the timing belt, which is often overlooked. Check for signs of aging in the timing belt, and replace it promptly if any abnormalities are found.
From my years of driving experience, I've concluded that major maintenance intervals are typically around 40,000 to 60,000 kilometers, depending on the vehicle brand and owner's manual. Taking my Toyota as an example, the manual recommends a comprehensive service at 60,000 kilometers, including oil and three-filter changes, as well as inspections of the braking system and transmission fluid. Don't overlook checks on the cooling system and steering mechanism, as neglecting these could lead to engine overheating or steering failure, potentially causing a breakdown. During my last major service at 50,000 kilometers, a minor oil leak was detected and repaired early, saving me thousands in potential repair costs. Regular maintenance not only ensures safety but can also extend a vehicle's lifespan by over 10 years. I recommend visiting a professional shop every six months or at the manual's specified mileage intervals—don't wait for problems to arise.
Prioritizing driving safety, I recommend performing a major maintenance every 50,000 kilometers. This involves a comprehensive inspection of the braking system, suspension, and tire wear to ensure reliability in critical moments. I once lost control in rainy weather due to excessive tire wear causing skidding, and since then, I've never neglected maintenance. Maintenance items typically include brake pad replacement, electrical system testing, and engine diagnostics, which can prevent hazards like steering failure or light outages. As the vehicle ages, the time interval becomes crucial too—conduct it at least every two years to prevent component corrosion. Once it becomes a habit, driving feels much safer, especially reducing the risk of malfunctions at high speeds.
