For a 100,000-kilometer major maintenance, the following items should be replaced: engine oil, engine oil filter, transmission fluid, fuel filter, spark plugs, air filter, cabin air filter, brake pads, brake discs, brake fluid, and coolant. Definition of car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Scope of car maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas.

I just completed the 100,000-kilometer major maintenance, and what impressed me most is not to underestimate these checkpoints. First off, the engine oil and filter must be changed immediately to ensure smooth engine lubrication for better performance. The spark plugs need to be inspected for wear or burn marks and replaced if necessary—otherwise, poor ignition can lead to sluggish acceleration. The braking system is critical: measure the brake pad thickness and replace if too thin, and don’t overlook brake disc wear checks—safety comes first. Suspension components like shock absorbers should be checked for oil leaks or unusual noises, while tire wear and pressure must be adjusted to optimal levels. Coolant should be refreshed to prevent overheating, and severely aged transmission fluid must be replaced. The timing belt is a hidden risk—inspect for cracks or tension issues, as a failure can lead to costly repairs. Replace the air filter and cabin air filter together to ensure fresh air inside the car. Test the battery voltage and address low readings early to avoid starting issues. In short, 100,000 kilometers is a turning point—a thorough inspection can prevent major issues and extend your car’s lifespan. Don’t hesitate to invest the time and money.

As someone who frequently drives long distances, I pay special attention to the 100,000-kilometer maintenance. The top priority is the safety components: the braking system and tires must be thoroughly inspected. The wear level of the brake pads should be measured by thickness to determine if replacement is needed, and the tire tread depth and pressure should be checked to ensure grip. For the engine, change the oil and test the performance of the spark plugs, as delayed ignition can easily lead to malfunctions. Don’t overlook the drivetrain—replace the transmission fluid to avoid accelerated wear. Inspect suspension components like shock absorbers for deformation or looseness to ensure driving stability. Update the coolant in the cooling system to prevent engine overheating and potential explosions. Test the battery voltage and replace it in time if its lifespan is up. Additionally, replace the air filter if it’s dusty, and check the fuel system for clogged filters. It’s recommended to go to a professional shop for a comprehensive inspection—these small investments can prevent unexpected accidents on the road and provide peace of mind.

The 100,000-kilometer major maintenance involves numerous inspection items, with a focus on practical upkeep. Replace the oil filter to ensure engine lubrication, and check spark plugs for ignition performance, replacing them as needed. Measure brake pad thickness in the braking system to assess if replacement is necessary. Inspect tires and suspension for wear and balance, performing alignment if required. Replace transmission fluid if it appears black or has an off odor, and test the cooling system's antifreeze effectiveness. Change the air filter if dirty to keep the engine breathing smoothly. Check the fuel filter for clogs to prevent fuel delivery issues. Evaluate the timing belt according to the manual to avoid breakage failures. While the process incurs some cost, it's worthwhile in the long run as it saves on major repair expenses.

When performing the 100,000-kilometer maintenance check by myself, I felt both excited and cautious. Starting with the simpler tasks: replacing the oil filter to check if the oil is clean; pulling out the spark plugs to inspect the electrode discoloration level to determine replacement. Measuring the brake pads with calipers and replacing them if they are too thin to ensure safety. Checking the tire tread depth for uniformity and adjusting the tire pressure to the standard value. Moving on to more complex tasks, testing the transmission fluid—if the color is dark or it has a sour smell, it indicates the need for replacement. Checking the cooling system to ensure the antifreeze's freezing point meets the standard and topping it up if necessary. Testing the suspension by listening for unusual noises to detect any looseness. Replacing the air filter if it's clogged with dust. DIY can save money, but it's essential to carefully follow tutorials and use the correct tools to avoid mistakes. For some tasks, it's more reliable to seek professional assistance.

A comprehensive inspection at 100,000 kilometers aims to prevent future high repair costs. Key items include: oil and filter replacement to maintain engine efficiency; spark plug testing for ignition performance, renewing if necessary; brake system inspection of pad and disc wear to ensure timely braking response and safety first. Tire wear measurement with rotation or replacement as needed; suspension components like shock absorbers checked for leaks to ensure smooth driving. Cooling system antifreeze renewal to prevent overheating failures; transmission fluid replacement if emulsified or aged to avoid shifting issues. Regular air filter changes ensure clean air intake; timing chain or belt tension assessment prevents breakage and extends engine life. Thoroughly completing these checks keeps the car running like new, saving money and hassle.
