What maintenance is required at 40,000 kilometers?
2 Answers
At 40,000 kilometers, the car maintenance items include replacing the engine oil, oil filter, and spark plugs, as well as inspecting the wheel hubs and braking system. Below are the detailed descriptions of the car maintenance items: 1. Engine oil and oil filter replacement: This mainly pertains to the maintenance of the lubrication system. The primary function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's role is to remove various impurities from the engine oil, ensuring the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, the car should be serviced every 5,000 kilometers. 2. Filter replacement: The air filter's function is to filter the air before it enters the cylinders, removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The gasoline filter is typically replaced after driving 20,000 to 25,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. In addition, components such as brake fluid, transmission oil, battery, throttle, fuel injectors, and brake pads are part of the inspection items during routine maintenance, with maintenance performed based on usage conditions.
I usually drive to and from work, and when the car reaches 40,000 kilometers, the maintenance items cannot be taken lightly. The most basic oil change and oil filter replacement are must-dos to ensure the engine runs smoothly, and I regularly check the oil quality myself. The air filter also needs to be replaced, as accumulated dust can affect performance; the cabin air filter is often overlooked, but after 40,000 kilometers, it can easily become clogged, leading to insufficient cooling. The braking system requires special attention, including brake pad thickness and brake fluid level, to prevent sudden failures. Tire wear inspection is also crucial, and I recommend wheel balancing or adjustment to ensure good grip. Other items such as coolant top-up, spark plug replacement (depending on the model), and transmission fluid check should not be neglected. Overall, timely maintenance can extend the car's lifespan and make driving more reassuring.
