What maintenance is required for a vehicle at 40,000 kilometers?

[AliyahLynn]

The 40,000-kilometer maintenance for a vehicle is a major service, primarily involving the replacement of engine oil, three filters, and all vehicle fluids, along with some essential routine inspection items, such as replacing brake fluid, transmission fluid, power steering fluid, and coolant. Other necessary maintenance tasks include: 1. Checking the wear condition of the brake pads, inspecting tire wear and tire pressure, and assessing the aging and wear of rubber components like the engine's external belts to ensure they are normal. Also, check for any oil leaks in the engine, transmission, and shock absorbers. 2. Additionally, based on the vehicle's usage, inspect the carbon buildup in the intake and exhaust systems. If necessary, perform cleaning and maintenance on the intake and exhaust systems as well as the lubrication system, which generally includes: cleaning the fuel injectors, cleaning the throttle body and idle valve, cleaning the intake manifold, cleaning the three-way catalytic converter, and cleaning the engine's lubrication system.
