What Does a Major Car Maintenance Include?
2 Answers
Major car maintenance involves replacing the engine oil, oil filter, air filter, and fuel filter. Below is an introduction to some car maintenance items: 1. Oil Filter: Typically replaced every 8,000 km or once a year. The oil filter provides clean fuel to the engine, filtering out water and impurities from the gasoline. A clogged oil filter can obstruct the flow of lubricating oil, leading to poor engine lubrication, increased wear, and even bearing failure. 2. Air Filter: The engine draws in a large amount of air during operation. If the air is not filtered, dust can accelerate wear on the piston group and cylinders. The air filter removes dust and particles from the air, ensuring sufficient and clean air enters the cylinders. 3. Fuel Filter: The fuel filter provides clean fuel to the engine, filtering out water and impurities from the gasoline. During car maintenance, technicians also perform inspections, cleaning, tire alignment checks, and checks on various fastening components.
I've been driving for almost 15 years, and I really need to explain major maintenance in detail. It's usually done every 20,000 to 40,000 kilometers or every two years, and it's more comprehensive than minor maintenance. Key tasks include changing the engine oil and oil filter, which is basic but essential; the air filter must also be replaced, as dust buildup can affect fuel efficiency; the fuel filter should be renewed to keep the fuel system clean; replacing spark plugs is crucial—if they're worn out, ignition becomes unstable. The braking system requires a thorough inspection, including brake pad thickness and brake fluid condition; tires need rotation and balancing to prevent uneven wear. Additionally, coolant and brake fluid levels should be checked, and chassis bolts must be tightened to prevent loosening. The cabin air filter and transmission fluid (for automatic transmissions) should also be inspected. This significantly extends engine life and prevents sudden breakdowns. I always stick to this routine—my car runs smoothly and reliably. The cost isn't too high, but the benefits are substantial.
