What Does the Fourth Car Maintenance Include?
2 Answers
The fourth car maintenance includes the following items: 1. Replace the engine oil, oil filter, clean the air filter, and check whether the generator belt and wiper blades are damaged; 2. Check whether the levels of various fluids are normal; 3. Check whether the tire pressure is normal and whether there is uneven wear, bulging, or damage on the tires; 4. Inspect the car chassis, including checking for any scratches on the brake pads, brake discs, connecting rods, ball joints, and CV joints; 5. Check whether all switches and lights in the car are working properly. The fourth car maintenance refers to the maintenance when the car's mileage reaches 20,000 kilometers. The precautions for maintenance are: 1. Make an appointment in advance; 2. Record any faults or questions encountered during daily driving and inform the staff during the maintenance registration.
The fourth maintenance is usually done when the car has run 20,000 kilometers or been in use for about two years. I've driven several cars, and the most crucial part is changing the engine oil and oil filter to protect engine lubrication. The air filter should also be checked or replaced—it filters out dust, allowing the engine to breathe smoothly. Next, rotate the tires to balance wear and extend their lifespan, and check if the tire pressure meets the standard. The braking system must be inspected carefully, including the thickness of the brake pads and the condition of the brake fluid, to avoid accidents while driving. Lights should be adjusted to ensure safe nighttime driving. Check the coolant level, and the spark plugs might need replacement—refer to the manual for specifics. Don’t forget to inspect the chassis and suspension components for any looseness or damage. I recommend going to a professional shop—they can test battery voltage and clear fault codes, preventing minor issues from becoming major ones. The whole process takes about one or two hours. Proper maintenance keeps the car running smoothly, saving fuel and ensuring safety.
