Major car maintenance includes the following items: 1. Engine oil: Changing the engine oil at 40,000 kilometers is the primary task. Engine oils include mineral oil, semi-synthetic oil, and fully synthetic oil, with quality increasing in that order. 2. Transmission fluid: Most car maintenance manuals recommend changing the transmission fluid every 2 years or 40,000 kilometers. The transmission connects the clutch and the drive shaft, and its internal gears are very precise. Frequent gear shifting can cause the transmission fluid to deteriorate. 3. Coolant: The replacement interval for car coolant is generally 2 years, and it usually comes in two colors: pink and blue. 4. Brake fluid: It is recommended to replace the brake fluid during the 40,000-kilometer major inspection, as brake fluid is prone to overheating, deterioration, and forming bubbles, which can reduce braking effectiveness. 5. Brake pads: Some domestic car maintenance manuals suggest replacing brake pads every 40,000 to 60,000 kilometers, as brake pads directly affect the braking safety of the car. 6. Power steering fluid: Power steering fluid is typically recommended to be replaced every 3 years or 60,000 kilometers, mainly to assist the car's steering system. 7. Filters: During routine maintenance, air filters and cabin air filters are cleaned with high-pressure air to remove dust, but they should be replaced during the 40,000-kilometer major maintenance.

I just had a major service on my car last week, and it feels much better now. A major service is usually done every 20,000 kilometers or so, and it includes quite a few items. Changing the engine oil and oil filter is the basics, which helps the engine run more smoothly and prevents excessive wear. Replacing the air filter is crucial, especially in dusty urban areas, as a dirty filter can affect air intake. A thorough inspection of the brake system is a must, including changing the brake fluid, otherwise, poor braking response could lead to accidents. Tire rotation and balancing are essential to ensure even wear and extend tire life. Replacing the spark plugs improves ignition efficiency and can even save some fuel. Coolant replacement prevents overheating and rust, extending the engine's lifespan. Changing the transmission fluid makes gear shifts smoother, especially in automatic cars. Testing the battery is important to avoid getting stranded on the road. It's also a good idea to check the chassis components, such as the suspension and shock absorbers, to ensure safety. After a major service, driving feels more secure, and it helps reduce unexpected repair costs.

Major car maintenance covers key service points. This includes oil and oil filter replacement to ensure engine lubrication and cleanliness. The air filter should also be renewed to prevent contaminants from damaging components. Brake system inspection is crucial, with brake fluid replacement enhancing braking responsiveness. New coolant helps the cooling system operate efficiently, preventing overheating issues. Spark plug replacement optimizes ignition performance, maintaining power output. Transmission fluid renewal ensures smooth gear shifting and reduces wear. Tire rotation and balancing promote even tread wear, extending service life. Battery and charging system testing prevents power supply problems. Additionally, belts, hoses, and other wear-prone parts should be inspected to detect potential issues early. This comprehensive maintenance prevents major failures, saves future costs, and enhances driving safety.

When performing a major car maintenance, safety should be the top priority. Focus on inspecting the braking system and replacing the brake fluid to ensure reliable braking and prevent accidents. Check tire pressure and wear levels to avoid the risk of blowouts. Maintain suspension and steering components to keep handling stable. Inspect all lights, including headlights and fog lights, to ensure clear visibility at night. Additionally, replace the engine oil and oil filter to protect the engine's lifespan. Change the air filter to prevent dust damage. Regularly performing these tasks can significantly reduce the likelihood of accidents, making every drive safer. Flushing the cooling system prevents rust and leaks, increasing reliability. Don’t underestimate these details—they can be lifesavers in critical moments.
