What are the maintenance items for a sedan?

[CoreyDella]

The maintenance items for a sedan include: 1. Routine maintenance: Generally refers to the regular maintenance after every 5,000 kilometers driven, which mainly involves changing the engine oil and oil filter, checking whether the fuel filter, air filter, and brake discs need replacement, whether brake fluid needs to be replenished, and inspecting the condition of the tires; 2. Periodic maintenance: Usually performed every 3 years or after every 40,000 kilometers driven. In addition to routine maintenance, it also requires cleaning the fuel injectors, throttle valve, and the vehicle's intake system; 3. Major maintenance: Typically occurs after the vehicle has been driven 100,000 kilometers, involving a comprehensive inspection of the vehicle and replacement of parts as needed. At this stage, it is essential to check the wiring, transmission mechanism, and other components.

I have quite some experience with sedan maintenance. The basics include regular oil and oil filter changes, which should be done every 5,000 to 10,000 kilometers. Dirty oil can cause premature engine wear. Tires also need frequent checks—measure the air pressure to ensure it's within the standard range, inspect the tread for severe wear, and replace them if uneven for safer highway driving. The braking system shouldn't be overlooked; check the brake pad thickness and brake fluid levels every six months to prevent leaks. Clean battery terminals to avoid corrosion from dust buildup. Inspect lighting systems like headlights and turn signals to ensure they work properly, as they're crucial for nighttime driving safety. Replace the cabin air filter annually for fresher air and comfort. Regular car washes and waxing keep the exterior looking good and prevent rust. By sticking to these routine maintenance tasks, your car will last longer, consume less fuel, and require fewer repairs. Saving money is secondary—safety is the top priority. Following these steps, like I do as a daily driver, makes car ownership worry-free.

I've been driving for over a decade and always approach sedan maintenance from a cost-saving perspective. I check the engine oil level every six months, topping up or changing it when low to avoid costly engine issues. I frequently replace the air filter myself to save on labor costs. Tire pressure gets measured monthly, keeping it at the manufacturer's recommended level to prevent blowouts from over/under inflation. The brake system gets inspected every 5,000 km - worn brake pads get replaced immediately to avoid dangerous braking delays. Before winter, I service the battery by cleaning terminals to minimize corrosion. Regular coolant level checks prevent engine overheating damage. Lighting inspections (headlights and brake lights) ensure functionality for safety and to avoid traffic tickets. Never neglect interior cleaning either - excess dust causes allergies. Ultimately, regular maintenance is far cheaper than repairs. Make it a habit and your car will run like new for a decade.

For sedan maintenance, I believe the focus should be on safety items. Oil change is fundamental, done every six months to ensure proper engine lubrication. Tire inspection is essential—check air pressure and tread wear; replace immediately if uneven or too thin to prevent high-speed blowouts. The braking system is critical; inspect brake pads monthly and replace if too thin, ensuring brake fluid doesn’t leak. Lights like headlights and brake lights must function for safe nighttime driving. Regularly clean battery terminals to prevent ignition failure. These routine maintenance tasks are simple—don’t procrastinate until major issues arise, as repairs are costly and dangerous. Develop these habits for safer driving and fewer accidents.
