What Items Are Replaced During the First Maintenance?

[IsaacAnn]

During the first maintenance of a car, the following items are primarily replaced: 1. Engine oil replacement: Due to insufficient break-in between various components during the running-in period, debris can easily mix with the oil, leading to excessive impurities that hinder effective lubrication. 2. Replacement of the three filters: The three filters in a car include the oil filter, fuel filter, and air filter. These filters provide a better working environment for the engine by preventing impurities from entering and affecting normal operation. 3. Checking the coolant level: The coolant level is inspected during the first maintenance to ensure it meets the specified range, preventing insufficient coolant from affecting its performance during driving. Typically, the antifreeze should be within the min and max range.
