What maintenance items are generally required for a car with over 20,000 kilometers?
3 Answers
For a car with over 20,000 kilometers, the general maintenance items include: changing the engine oil, oil filter, air filter, cabin air filter, and spark plugs. Routine inspections involve checking the coolant, brake fluid, and transmission fluid, as well as inspecting and tightening all bolts on the chassis and examining the electrical circuit operation. The benefits of car maintenance are: 1. Keeping the car clean, maintaining normal technical conditions, eliminating potential hazards, preventing faults, slowing down the deterioration process, and extending the service life; 2. Conducting regular preventive work on relevant parts of the car, including inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain components; 3. Maintenance work essentially involves cleaning, tightening, inspecting, and replenishing.
I've been driving for over a decade, and the 20,000 km maintenance mainly involves basic items. Changing the engine oil and oil filter is a must, and the air filter should also be replaced since it's accumulated a lot of dust after 20,000 kilometers. Check the tire wear and perform a tire rotation to ensure even wear on all four tires, which helps them last longer. Measure the thickness of the brake pads; if they're below 3mm, it's time to replace them. Inspect and tighten the chassis bolts to avoid strange noises at high speeds. Replace the cabin air filter if necessary—if there's a musty smell, address it immediately. The mechanic will also check details like lights, wipers, and brake fluid levels. I always ask them to test the coolant and battery condition to prevent minor issues in advance. After maintenance, the car runs smoothly, and I don’t have to worry about engine overheating even in city traffic.
My car just passed the 25,000 km maintenance. Besides the basic oil and filter change, I paid extra attention to a few areas. The battery, which has been in use for over two years, was tested by the technician to check its lifespan to avoid breaking down midway. The tires were balanced and rotated, and now the steering wheel doesn’t shake at high speeds. Cleaning the throttle body was crucial, and the accelerator feels much lighter. The brake fluid’s water content was also checked, as exceeding the limit can affect braking distance. The spark plugs were removed to inspect the ignition gap, and carbon deposits were cleaned. The wiper blades were replaced with new ones, improving visibility on rainy days. The spare tire in the trunk was topped up with air, and the tool kit was checked to ensure it’s complete. The total cost was around 800 yuan, but the car’s condition is almost as good as new, and the air conditioning cools more effectively. I recommend observing the maintenance process—technicians tend to be more meticulous when you’re watching.
