2 Answers
Here are the parts that need to be replaced during the second maintenance of a car: 1. Engine oil and oil filter; 2. Air filter; 3. Fuel filter; 4. Transmission oil; 5. Cabin air filter. The following items need to be inspected during the second maintenance: 1. Spark plugs, brake fluid, throttle valve; 2. Fuel injectors, tires and braking system, engine belt; 3. Performance of headlights, warning lights, turn signals and car horn. Extended information: The second maintenance of a car refers to secondary maintenance or secondary service. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting or replacing certain parts of the car, also known as car servicing.
The second maintenance typically requires changing the engine oil and oil filter, which is the most basic. My car is a compact model, and the mileage during the last second maintenance was around 5,000 kilometers. The mechanic at the repair shop said it's also necessary to check the air filter, and if it's too dirty or clogged with dust, it should be replaced as well. Additionally, as the engine runs for a long time, the oil thickens, affecting lubrication, so regularly changing the oil can protect the engine's lifespan. It also involves inspecting or replacing the fuel filter to prevent impurities from entering the fuel injection system. Other parts such as brake pads, tire wear, and coolant may also need replacement based on the inspection results. I recommend not just replacing parts but also conducting a comprehensive check of the lights, suspension, and battery to ensure daily driving safety. In short, the second maintenance is not just about replacing parts; it involves the overall health maintenance of the vehicle.
