What parts need to be replaced after a car reaches 100,000 kilometers?
1 Answers
After a car has been driven for 100,000 kilometers, even if it is in good condition, the following five parts need to be replaced or maintained: 1. Tires: Car tires are primarily made of rubber. Although they are treated with special materials and manufacturing processes to enhance durability, normal driving causes constant friction between the tire tread and the road surface, while also bearing the weight of the vehicle, passengers, and cargo. Over time, the tread wears down, reducing grip, and the rubber naturally ages. Generally, tires on family cars should be replaced every 60,000 kilometers. 2. Vehicle fluids: The most important ones are engine oil, brake fluid, and coolant. Engine oil plays a crucial role in lubricating engine components, and its replacement interval depends on its composition. Brake fluid has a relatively longer lifespan and should be replaced every two years, while coolant typically needs to be replaced every 40,000 kilometers. 3. Spark plugs: These components ignite the mixture of fuel and air in the engine's combustion chamber. The timing and frequency of ignition directly affect engine performance. Spark plugs gradually degrade due to repeated high-voltage discharges and exposure to high temperatures and pressures. Therefore, they should be replaced after a certain mileage: standard resistor spark plugs every 20,000 kilometers, platinum spark plugs around 40,000 kilometers, and iridium spark plugs up to 70,000 kilometers. 4. Brake pads: The braking force of a vehicle relies on friction between the brake pads and brake discs. Over time, the softer brake pads wear down, reducing their thickness and braking efficiency. Typically, brake pads should be replaced every 30,000 to 60,000 kilometers. 5. Engine maintenance: The engine is the heart of the vehicle and requires regular maintenance. In addition to inspecting key components, a critical task is cleaning carbon deposits. Methods include using fuel additives like "fuel system cleaners" and periodically cleaning the engine throttle body.
