I remember during the last second maintenance for my car, the technician focused on checking several key areas. The most basic tasks included changing the engine oil and oil filter, as the engine needs clean oil to run smoothly. The air filter was also taken out and cleaned, and if it was too dusty, a new one was installed. The tires were carefully checked for pressure and wear, and their positions were rotated. The brake pads were inspected for thickness, and if they were too thin, preparations were made to replace them. The technician also used a computer to read the vehicle's ECU data, saying it was to check for any hidden fault codes. Finally, the car was lifted to inspect the undercarriage for any scratches or oil leaks. The entire process took about an hour and cost over a thousand yuan. According to the maintenance manual, these are the main routine items for the second maintenance.
The second maintenance is not just about changing the engine oil. First, the old engine oil and oil filter that have run for 7,000-8,000 kilometers must be replaced—this is the most basic. The air filter should also be replaced if necessary, otherwise, the engine will struggle to breathe. The key is to check the tire condition, including tire pressure, wear, and wheel alignment. The braking system must be inspected carefully; brake pads thinner than 3 millimeters are dangerous. Various fluids should also be checked, such as power steering fluid, brake fluid, and coolant—top them up if they are low. Don’t forget the lighting check; last time, I found the reverse light had poor contact. Finally, have the mechanic scan for trouble codes with a diagnostic tool—dozens of sensors must be confirmed to be working properly before the job is done.
