What Maintenance Should Be Done at 20,000 Kilometers?
1 Answers
For a vehicle that has traveled 20,000 kilometers, the following maintenance should be performed: 1. Replace the engine oil and oil filter. This is a mandatory item for every maintenance service. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance deteriorates considerably. Over time, it can no longer protect the engine effectively. The oil filter is designed to filter out impurities, providing protection for the engine. Therefore, both the engine oil and oil filter should be replaced simultaneously. 2. Inspect the air filter. The air filter reduces the intake of air containing impurity particles, thereby minimizing the risk of wear and damage. During the 20,000-kilometer maintenance, check if the air filter is dirty. If it is excessively dirty, replace it; if not, simply clean it with an air gun. 3. Check the spark plugs. In a gasoline engine's ignition system, spark plugs introduce high-voltage current into the cylinders to generate sparks, igniting the combustible air-fuel mixture. If you notice a lack of power, it may be time to replace the spark plugs. The lifespan of spark plugs varies depending on the material: iridium spark plugs should be replaced every 80,000–100,000 kilometers, platinum spark plugs every 50,000–60,000 kilometers, and nickel spark plugs every 20,000–30,000 kilometers. 4. Inspect the brake pads. During the 20,000-kilometer maintenance, check the thickness of the brake pads. If they are excessively worn, it is advisable to replace them to ensure driving safety.
