Below are the car maintenance items: 1. Engine Oil Change: Regular car maintenance (every 7,000-10,000 kilometers) requires an oil change. Engine oils include mineral oil, semi-synthetic oil, and fully synthetic oil, with quality increasing in that order. Semi-synthetic oil can last for 5,000-7,000 kilometers. If you have fewer maintenance sessions within a year, fully synthetic oil is recommended for better quality. 2. Transmission Fluid Change: Most car maintenance manuals specify that transmission fluid should be changed every 2 years or 40,000 kilometers. Transmission fluid is typically replaced during a 'major' maintenance session. The transmission connects the clutch and the drive shaft, with internal gears being highly precise. Frequent gear shifts can cause the transmission fluid to degrade, reducing its cooling and lubricating effects and making the transmission more susceptible to damage. Therefore, it is advised to follow the maintenance manual for transmission fluid changes. 3. Coolant Change: The coolant in a car is generally changed every 2 years. It comes in pink or blue colors. Since coolant is not very expensive, it is recommended to follow the car's maintenance manual for replacement. Most cars require a coolant top-up after driving 40,000 kilometers. 4. Brake Fluid Change: Brake fluid serves as the power transmission medium in the car's braking system. Its quality directly affects braking performance, so it is recommended to change it at 40,000 kilometers. This is because brake fluid can degrade and form bubbles when heated, leading to reduced braking effectiveness. 5. Brake Pad Inspection and Replacement: Brake pad replacement depends on wear and tear during inspection. Some domestic car maintenance manuals suggest replacing brake pads every 40,000-60,000 kilometers. Brake pads directly impact braking safety, and wear varies, so replacement should be based on actual condition. 6. Power Steering Fluid Inspection and Replacement: Power steering fluid is typically changed every 3 years or 60,000 kilometers. It is essential for the car's steering system. Low power steering fluid can make steering feel heavy.

I've been driving for over a decade, and major maintenance is something worth emphasizing. Beyond the essential oil and three-filter changes, transmission fluid needs a complete replacement every 60,000 km; otherwise, gear shifts will feel rough. Brake fluid must be replaced if its water content exceeds standards, as it affects braking distance. Spark plug replacement intervals depend on material: standard nickel alloy lasts 40,000 km, while iridium can go 80,000 km. Tires require rotation and four-wheel alignment to prevent uneven wear that can be costly. Checking belts for cracks is crucial—a snapped belt can leave you stranded. Don't forget to clean throttle body carbon buildup to improve fuel efficiency. Finally, have the mechanic scan for trouble codes to check ABS and EPS systems. The whole package typically costs between 1,500 to 3,000 yuan, depending on the vehicle model.

Last time I gave my old Camry a major service, there were quite a few items. Oil and oil filter changes are basic, and the cabin air filter needs replacing too, otherwise it blows out a musty smell. Key inspection points are the chassis rubber bushings and ball joints - aging can cause squeaking. Coolant should be changed every two years to prevent freezing/boiling and protect the engine. Test the battery life - replace immediately if below 50%. Brake discs/pads must be addressed if under 3mm thickness - safety first. The fuel filter is often overlooked, but clogged fuel lines are troublesome. It's best to do interior sanitization and odor removal at the same time, especially for families with children. I recommend bringing your own high-quality parts to the repair shop - it can save significant labor costs.

Comprehensive inspection is key in major maintenance: Check timing chain wear for the engine, and replace the clutch three-piece set for manual transmissions. Update the brake fluid and brake pads in the braking system. Steering becomes lighter after replacing the power steering fluid. Inspect the chassis for shock absorber leaks and ball joint looseness. Test the performance of the alternator and starter in the electrical system. Clean carbon deposits from the fuel injectors in the fuel system to improve fuel efficiency. Check tire tread depth and uneven wear. Finally, be sure to update the three fluids: coolant for antifreeze and anti-boil, windshield washer fluid should be antifreeze type, and transmission fluid to extend lifespan. It is recommended to choose the original manufacturer's maintenance package for peace of mind.
