What maintenance is needed when a car reaches 40,000 kilometers?
1 Answers
When a car reaches 40,000 kilometers, the main maintenance items include replacing the air filter, oil filter, fuel filter, and all vehicle fluids, as well as some necessary routine inspection items such as replacing brake fluid, transmission fluid, power steering fluid, and coolant. Below are the relevant details: 1. Replacing the engine oil and oil filter is a mandatory task. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of the oil is significantly shortened, and its performance deteriorates greatly, eventually failing to protect the engine. The oil filter prevents impurities from mixing with the oil, which can cause oxidation and produce sludge that clogs the oil passages. The oil and oil filter should be replaced simultaneously. 2. The air filter should be replaced every 10,000 to 15,000 kilometers. 3. If the spark plugs have not been replaced before, they must be replaced during the 40,000-kilometer maintenance. Although the spark plugs may not have completely failed by 40,000 kilometers, their ignition performance has significantly degraded, directly affecting the engine's power, performance, and fuel consumption. 4. Additionally, it is time to replace the tires and battery. Even if the tires are not severely worn, after 40,000 kilometers, they have been in use for a considerable time and have started to age. As for the battery, check if it is undercharged. If you frequently experience difficulty starting the car in daily use, it is advisable to consider replacing the battery.
