What maintenance should be done at 25,000 kilometers for a car?

[Doreen]

At 25,000 kilometers, the maintenance for a car includes changing the engine oil, oil filter, air filter, cabin air filter, and fuel filter. It also involves checking the tread depth, tire pressure, and wear condition of the tires, with a wheel alignment performed if necessary. The throttle body and idle speed valve should be inspected for excessive dirt and cleaned if needed. The condition of the spark plugs should be checked and replaced if necessary. For vehicles that have reached 25,000 kilometers, the maintenance should also include inspecting the power steering, braking system, and automatic transmission. Tests should be conducted to ensure the braking force, gear shifting, and steering are functioning properly. Additionally, the levels of various fluids should be checked to ensure they are at the standard positions, the tightness of the chassis bolts should be verified, and the lighting system should be inspected for proper operation.
