Classification of routine maintenance

Routine maintenance is generally divided into small maintenance and major maintenance.

Minor maintenance generally refers to the replacement of the oil and oil filter, which is usually carried out once every 5,000 kilometers.

Major maintenance generally involves replacing the oil, oil filter, air filter, gasoline filter, air-conditioning filter, spark plug, brake oil, and gearbox oil, usually once every 40,000-60,000 kilometers.

Which parts of the vehicle should generally be maintained

Engine: oil, coolant, spark plug, fuel injector, fuel filter, air filter, various gaskets (valve cover gasket, cylinder head gasket, oil pan gasket)

Transmission: Transmission oil

Brake system: brake pads, brake discs, brake fluid

Air conditioning system: refrigerant (refrigerant), air conditioning filter

Steering machine: Steering machine oil

Rubber parts: engine foot rubber, suspension swing arm rubber support, shock absorber rubber support, front and rear axle rubber pads, tires, crankcase rear oil seal, gearbox front oil seal, drive shaft transmission damping rubber (rear wheel drive cars ), wiper.

Power supply: battery

Maintenance interval for some wear parts

Engine oil: generally 5000 km-10000 km (depending on the engine model and the oil grade used).

Gasoline filter element, air filter element, air-conditioning filter element: generally replaced once every 20,000 kilometers.

Coolant (antifreeze): It is recommended to replace it once 20,000 kilometers. Insufficient coolant concentration will cause the engine to boil.

Spark plug: It is recommended to replace it every 30000-40000 kilometers. Aging spark plugs can cause insufficient power or engine shake.

Transmission oil: generally change once for 40,000-60,000 kilometers.

Brake fluid: It is recommended to replace it every 2 years or 40,000 kilometers. Brake fluid is a kind of fluid with strong water absorption. The internal moisture vaporization of brake fluid that deteriorates after absorbing more water will affect the braking performance during braking.
