What maintenance is required for a new car at 30,000 kilometers?

[ORiver]

After a car has been driven for 30,000 kilometers, a major maintenance service is required. The maintenance items generally include the following points: 1. Replace engine oil and oil filter: This is a relatively routine maintenance item and is replaced in almost every maintenance service. Replacing the engine oil and oil filter can enhance the lubrication of the engine, allowing it to work more efficiently. 2. Replace the air filter: After driving 30,000 kilometers, some impurities can easily clog the air filter, affecting the normal operation of the car's air conditioning system. 3. Check the coolant: Car coolant is a consumable that protects the normal use of the car engine, preventing the engine from 'boiling over' due to high temperatures. 4. Clean the engine: Add a professional engine cleaner and let the vehicle idle for about 15 minutes, which helps extend the engine's service life. 5. Check the transmission: Inspect whether the transmission is functioning properly and whether the transmission fluid is sufficient. 6. Check the braking system: Examine the wear level of the brake pads and whether the brake fluid level is normal. 7. Check the tires: Inspect whether the air pressure in the car tires and spare tire is normal and whether the tires are worn. 8. Check the lights: Ensure that the car's taillights, warning lights, turn signals, high and low beams, etc., are functioning properly. 9. Clean carbon deposits: Cleaning carbon deposits can make the vehicle's power more robust and also reduce fuel consumption.
