How many kilometers does a car need for a major maintenance?
2 Answers
Generally, a major maintenance is performed every 40,000 kilometers. However, this interval is not completely fixed, as some car models may require a major maintenance every 60,000 kilometers. The specific timing should follow the maintenance manual (vehicle user manual) as it provides detailed instructions. Additional information: 1. Major maintenance is based on minor maintenance. Regular minor maintenance only requires changing the engine oil and oil filter, while major maintenance involves more items. In addition to engine oil and oil filter, major maintenance generally includes the following items: 1) Replacing the air filter, cabin air filter, and fuel filter. 2) Transmission fluid. 3) Brake fluid. 4) Coolant. 5) Spark plugs. All of the above items usually need to be replaced. 2. Additionally, tires and brake pads should be thoroughly inspected, and if severe wear is detected, they must be replaced promptly. The replacement intervals for these parts can vary significantly due to various objective factors, but they are generally replaced around 40,000 to 60,000 kilometers. Another important component is the timing belt. The timing belt is a crucial part that is often overlooked. Check for signs of aging in the timing belt, and if any abnormalities are found, it should also be replaced promptly.
I've been repairing cars for over 20 years and have seen too many vehicles fail due to improper maintenance. Major maintenance should be done between 40,000 to 60,000 kilometers, but it depends on the specific situation. Japanese cars like Toyota and Honda usually need it at 40,000 km, while German brands like BMW and Mercedes might stretch to 60,000 km, but these are just reference values. If you frequently drive short distances in congested cities with high wear, you should move it up to 35,000 km; long highway trips with less wear can allow for slightly later maintenance. The key is that major maintenance includes oil changes, brake disc inspections, cooling system checks, and transmission fluid replacement—don't wait until warning lights come on to fix things. Finding a reliable shop to thoroughly inspect component conditions is much smarter, as it makes your car last longer with fewer repairs and runs smoother. Regular maintenance not only saves money but also gives peace of mind.
