Maintenance items required for a car at 40,000 kilometers include: 1. Inspect the engine, chassis, and transmission; 2. Clean the engine and throttle body; 3. Clean the air conditioning system; 4. Replace the brake fluid, coolant, and transmission fluid; 5. Check the air filter and cabin air filter; 6. Replace the engine oil, oil filter, and spark plugs; 7. Inspect the wheels and braking system. The benefits of car maintenance are: 1. Ensuring the vehicle remains in optimal performance condition; 2. Improving the vehicle's efficiency and reducing wear on parts and tires; 3. Preventing issues during travel and ensuring personal safety; 4. Reducing noise and environmental pollution; 5. Maintaining the vehicle's appearance and preventing unnecessary damage.
Just completed the 40,000 km major maintenance on my car, sharing my experience. This service was quite comprehensive. Started with fresh engine oil and a new oil filter - it's like giving the engine a blood transfusion. The cabin air filter was a must-change; last time I skipped it and ended up with musty air blowing through the vents. Did tire rotation and balancing - the front tires showed significant wear, but the improved grip after swapping was noticeable. Brake fluid test revealed excessive moisture content, so replacement gave peace of mind. When inspecting the spark plugs, the mechanic found electrode erosion and warned that delayed replacement would affect ignition efficiency. Although the manual recommends transmission fluid change at 60,000 km, early replacement better protects the gears. Also checked the suspension bushings - some cracks but still good for about six months. Total cost came to ¥1,200, but the car definitely runs smoother now. My advice: follow the maintenance schedule strictly and don't skip items to save money.
During my last 40,000 km maintenance service, I focused on several key items. The top priority was changing the engine oil and oil filter - this is absolutely not an area to cut corners. The air filter must be checked - with Beijing's air quality, a filter after 40,000 km is basically clogged like felt. Tire rotation is a money-saving trick - even wear can extend the life of all four tires by about 10,000 km. What surprised me was the coolant test - the freezing point had dropped to -15°C, which could have frozen and cracked the radiator in winter, so I replaced it immediately. The most expensive item was the transmission fluid - while the drained fluid looked okay, the mechanic said metal particles inside could wear down the gears. I also specifically asked them to check the alternator belt - fortunately no cracks were found. After completing these services, I noticed the engine sounds smoother. Remember - rubber components like belts must be replaced when due, as breaking mid-drive would be troublesome.
