2 Answers
Sedan maintenance items include: 1. Changing engine oil and transmission fluid; 2. Replacing spark plugs; 3. Replacing oil filters, cabin air filters, and engine air filters; 4. Cleaning throttle bodies and fuel injectors; 5. Checking brake fluid levels and potential leaks; 6. Adjusting brake pedal travel; 7. Topping up radiator coolant; 8. Adjusting ignition timing; 9. Inspecting engine cylinder head bolt tightness. Vehicle maintenance refers to periodic preventive work involving inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain components, also known as vehicle servicing. The purposes of vehicle maintenance are: 1. Maintaining vehicle appearance and cleanliness; 2. Eliminating potential hazards and preventing malfunctions; 3. Slowing component deterioration and extending service life.
I've been driving for over a decade, so I've got to keep maintenance items firmly in mind. The most basic is changing the engine oil and oil filter, which should be done every 5,000 to 8,000 kilometers to protect the engine from seizing up. The air filter also needs regular replacement—if it gets clogged with dust, the engine can't breathe properly and burns more fuel. Check the spark plugs for wear; if ignition isn't smooth, acceleration lags and fuel consumption increases. The braking system is absolutely critical: if the brake pads are worn thin or the brake discs overheat, it's unsafe and must be addressed immediately. Brake fluid should be replaced every two years to prevent corrosion in the lines. Check tire pressure monthly to balance wear and avoid dangerous blowouts. Coolant should be replaced every two years to prevent boiling in summer and freezing in winter. Worn-out wiper blades won't clear the windshield properly in rain, making it hard to see the road—replace them promptly when they degrade. Test the battery voltage every two years to avoid cold-weather starting issues. Don't skimp on overall maintenance—spending a little now avoids costly major repairs later. Neglecting upkeep leads to early vehicle scrapping, which isn't cost-effective. Regular comprehensive checkups at the shop ensure safety and longevity.
