What Generally Needs to Be Replaced During a Car's First Maintenance?

[DanielAnn]

During a car's first maintenance, engine oil, oil filter, transmission fluid, and rear axle oil are generally replaced. Below is detailed information about a car's first maintenance: 1. The first maintenance must be performed within 5,000 kilometers or six months of driving, whichever comes first. Typically, the ideal time for the first maintenance is between 4,000 and 5,000 kilometers. 2. The key tasks of the first maintenance for a new car are replacing the engine oil and oil filter. Since the period before the first maintenance is the break-in phase of the vehicle, the gradually breaking-in engine will mix mechanical impurities such as dust, metal wear, and carbon deposits into the oil. Replacing the oil and filter during the first maintenance is crucial, as debris generated by the engine, if not promptly removed, may cause abnormal damage to the internal parts of the cylinders. 3. Tightening nuts. During the first maintenance, the nuts in various parts of the new car should be inspected. Many vehicles leave some nuts slightly loose during manufacturing, considering the break-in period of the new car. During the first maintenance, all nuts will be tightened to the specified torque according to regulations.
