What Maintenance is Required for a Car at 25,000 Kilometers?

[LeIvan]

The maintenance items at 25,000 kilometers include changing the engine oil and transmission fluid, replacing the antifreeze, replacing the air filter, and inspecting the brake pads. After reaching the time or mileage specified by the manufacturer, a major maintenance is typically performed every 20,000 kilometers. Here is the maintenance required for a car at 25,000 kilometers: Change the engine oil. Replace the engine oil (lubricant) and oil filter: This must be done every 5,000 kilometers or six months. If full synthetic oil is used, it can be changed every 8,000 kilometers at most. Replace the transmission fluid. Changing the transmission fluid is an important task. The transmission is the link between the clutch and the drive shaft, and its internal gears are very precise. Frequent gear shifting can easily cause the transmission fluid to deteriorate, which then fails to provide cooling and lubrication, making the transmission more susceptible to damage. Therefore, it is recommended to change the transmission fluid according to the maintenance manual. Replace the antifreeze. The replacement time for car antifreeze is generally two years, which aligns well with the major maintenance cycle of 120,000 kilometers. Antifreeze usually comes in two colors: pink and blue. Since the cost of antifreeze is not high, it is recommended to replace it according to the car's maintenance manual. Replace the air filter. Replace the air filter and cabin air filter: These should be changed every 20,000 kilometers or two years. Inspect the brake pads. Although there is no fixed requirement for when to replace brake pads, it mainly depends on the car's usage habits. It is recommended to inspect the brake pads when the car reaches 20,000 kilometers. If the brake pads are less than 5mm thick, they need to be replaced. Car maintenance generally includes the following inspection or replacement items: Check if the coolant level meets the specified requirements; inspect the brake and clutch fluid levels; check if the power steering fluid reservoir level complies with the specifications; examine all system oil pipe interfaces for leaks; inspect the battery fluid level and windshield washer fluid level; check the tension and aging of the generator, air conditioning, water pump, and power steering pump belts; ensure all front and rear lights are functional (including headlights, width lights, turn signals, brake lights, reverse lights, and fog lights); check tire pressure and wear, tighten the tire bolts to the specified torque, replenish tire pressure to the model's specified value, and rotate the tires based on wear; verify that the car's exhaust emissions meet standards. 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. Modern car maintenance mainly includes the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down deterioration, and extend the service life.
