Change engine oil: Replace every 5,000 km or 6 months. Engine oil has the effect of lubricating, cooling, cleaning, anti-rust ... for automobile engines. If the engine oil is not replaced periodically, it will cause the engine to wear out quickly, be easily damaged, and the car will overheat.

Engine oil filter: Replace periodically every 10,000 km. The engine oil filter removes impurities before the oil enters a new lubrication cycle. If the oil filter is not replaced periodically then the oil quality will be affected.

Replace engine air filter: Periodically clean every 10,000 km, periodically replace every 20,000 - 30,000 km. The engine air filter removes dust and dirt from the air before it enters the combustion chamber. If the air filter is not replaced periodically, the filter may become clogged with dirt. This prevents air from entering the combustion chamber, affecting the air-to-air ratio.

Fuel filter: Replace every 40,000 km or 2 years. The fuel filter removes impurities before the fuel enters the combustion chamber. If the fuel filter is not replaced periodically, the fuel can become contaminated, reducing combustion efficiency, affecting engine power.

Spark plugs: Clean periodically every 20,000 km, periodically replace every 40,000 km with normal spark plugs, every 100,000 km with Iridium spark plugs. Spark plugs are responsible for creating sparks that ignite the mixture of fuel and air for the engine to work. After working for a long time, spark plugs are easy to get dirty, worn, flowing... leading to weak ignition, slow ignition, no ignition, etc., so they need to be cleaned and replaced periodically.

Injectors: Periodic cleaning every 20,000 km. The injector is responsible for injecting fuel to create combustion inside the combustion chamber. After a long time working, the injectors are often stuck with a lot of soot and dirt, so they need to be cleaned.

Engine coolant: Check and replenish periodically every 10,000 km, periodically replace every 40,000 - 60,000 km. Coolant has a cooling effect on car engines. After working for a long time, engine coolant can get dirty, degraded, etc. need to be checked and replaced periodically.

Check valve clearance adjustment: Periodic check every 40,000 km. When the engine is working, the valve is exposed to high-temperature combustion gas, so it is easy to expand. Therefore, it is necessary to have a gap so that when expanded, it can still close at the end of the compression stroke. However, if the gap is too large, it will cause the valve opening/closing time to be incorrect. Therefore, it is necessary to regularly check and adjust the valve clearance to the correct standard.

Camshaft drive belt: Replace periodically every 100,000 km. The cam belt connects the camshaft flywheel and the crankshaft to create a synchronized and matched movement. After a long time working, the cam belt is often worn, cracked, etc., so it needs to be replaced periodically.

Engine belts: Periodically check every 100,000 km (replace if necessary). The engine belt helps the machine drive the air conditioning system, water tank, power steering pump, generator... After a long time of working, the belt can wear and crack, so it needs to be checked periodically and replaced when being downgraded.

Idle speed adjustment test: Periodic check every 100,000 - 120,000 km. The idle control valve helps control the engine speed at idle. After a long time of working, sometimes the valve will be misaligned, so it needs to be checked and adjusted.

gearbox oil: Replace periodically every 40,000 - 60,000 km. Gear oil has the effect of lubricating, cleaning, and preventing rust for the components inside the gearbox. After a long time of working, the number of oil boxes will be dirty, degraded, uncertain level ... so it needs to be replaced periodically.

Change the axle oil (transmission oil): Replace periodically every 40,000 km. Bridge oil has a lubricating effect, reducing friction for the communication system.

Check and maintain front/rear brakes: Periodically check every 10,000 km or 6 months. The car brake system must operate with high frequency in harsh conditions due to the large frictional force. Therefore, it is necessary to check thoroughly. Brake test items include checking brake pads, brake cylinders, brake boosters, brake pedals, ABS brakes, etc.

Check and adjust the parking brake: Periodically check every 20,000 - 40,000 km. The parking system helps to determine when the vehicle is parked. Although the parking brake has to withstand less load than the foot brake, it works more, so it also needs to be checked and adjusted periodically.

Change brake fluid: Periodically check every 10,000 km, change periodically every 2-3 years. Brake fluid is responsible for transmitting force to the brake system. However, after a long time of working, brake fluid is often contaminated with water, making it easy to absorb moisture, in addition, the oil is also contaminated. That needs to be replaced periodically.

Tire rotation: Rotate tires periodically every 10,000 km. Because the weight is unevenly distributed across the axles, the tires will wear unevenly. Therefore, it is necessary to rotate the tires periodically to help the tires wear evenly, making the most of the life of the tires.

Check the air conditioning, fan, heating system: Periodically check every 5,000 km or 6 months. Check and clean the air conditioner filter, clean the cooler (every 40,000 km), change the gas filter (every 2 years), check the gas/replenish refrigerant if lacking...

Check ventilation valves, crankcases, pipes and connections:Periodically check every 20,000 – 40,000 km./p>

Check the car horn system: Periodically check every 5,000 km or 6 months.

Check the dust-proof rubber and rollers: Periodically check every 10,000 km or 6 months.

Check suspension system (shock absorbers, springs...), transmission shaft dustproof rubber: Periodic check every 10,000 km or 6 months.

Exhaust system check: Periodic check every 10,000 km or 6 months.

Check fuel tank cap, pipes, fuel system connections: Periodically check every 10,000 km or 6 months.

Check steering wheel rotation speed, link bars, steering wheel: Periodically check every 10,000 km or 6 months.

Check windshield washer fluid, wipers: Periodically check every 5,000 km or 6 months.

Check tire pressure, tire wear: Periodically check every 5,000 km or 6 months.

Check battery, electrode wear:Periodic check every 5,000 km or 6 months.

Check vehicle lights system: Periodically check every 5,000 km or 6 months.
