2 Answers
After a car reaches 40,000 kilometers, the required maintenance items mainly include changing the engine oil, three filters, and all vehicle fluids, as well as some essential routine inspection items such as replacing brake fluid, transmission fluid, power steering fluid, and coolant. The following is an introduction to car maintenance: 1. Definition of Car Maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Scope of Car Maintenance: Modern car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. Purpose of Car Maintenance: The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate hidden dangers to prevent failures, slow down the deterioration process, and extend the service life.
As an experienced driver who has driven many cars, after 40,000 kilometers, I focus on several key maintenance items: First is changing the engine oil and filter, which is the foundation of every service. Delaying oil changes may lead to excessive engine wear and affect its lifespan. Second is the braking system—checking brake pad wear and whether the brake fluid needs replacement. Safety comes first, after all, as brake failure at high speeds is extremely dangerous. Third is the tires—ensuring sufficient tread depth and getting a wheel alignment to prevent pulling or uneven wear. Fourth is the air filter and cabin air filter, often overlooked but clogged filters can impact engine performance and in-cabin air quality. Fifth is the spark plugs—some cars experience aging by 40,000 km, causing misfires and increased fuel consumption. Additionally, I check the coolant and battery condition. In summary, maintenance at this stage is mainly preventive to avoid major issues. I recommend visiting a dealership or reputable repair shop for professional service to save on costly repairs later.
