What needs to be replaced for a two-year car maintenance?

[Adeline]

For a two-year car maintenance, you need to replace the coolant, brake fluid, power steering fluid, and transmission fluid. Coolant: The full name should be antifreeze coolant, meaning it has antifreeze functionality. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold seasons when the car is parked. However, it's important to correct a misconception: antifreeze is not just for winter use; it should be used year-round. In regular car maintenance, the engine coolant should be replaced every year of driving. Brake Fluid: There are three types of brake fluid. When purchasing, choose a reliable manufacturer, and the higher the grade, the better. The working pressure of brake fluid is generally 2MPa, and it can go up to 4~5MPa. All fluids have the characteristic of being incompressible. In a sealed container or a fluid-filled pipeline, when pressure is applied to the fluid, it quickly and evenly transmits the pressure to all parts of the fluid. Hydraulic braking works based on this principle.

My car just turned two years old, and I did a maintenance service with quite a few replacements. Sharing this to help others avoid pitfalls. The basic items that must be replaced are the engine oil and oil filter, which need to be changed periodically to keep the engine running smoothly. The air filter should also be replaced as two years of use have accumulated a lot of dust, affecting air intake efficiency. Don’t forget the cabin air filter—after prolonged use, air quality deteriorates, and replacing it makes the car much more comfortable. Additionally, brake fluid is recommended to be changed every two years because it tends to absorb moisture, which can compromise braking safety. If the tires have run about 20,000 km and are worn out, consider rotating or replacing them. Check the spark plugs to see if they need replacement, as worn-out plugs can affect fuel efficiency and starting. Maintaining the coolant properly helps prevent engine overheating issues. In short, don’t skimp on small expenses—regular maintenance ensures safety and extends the car’s lifespan. My experience is that the car runs much smoother after servicing.

After driving this car for two years, the maintenance replacements have been quite practical. Changing the engine oil and oil filter is a must—it's routine to keep the engine healthy. After replacing the air filter, there's less dust, and breathing feels better while driving. Don’t overlook the cabin air filter; if it’s been used for too long and the smell is bad, replace it promptly. Brake fluid should be changed every two years—it’s crucial to avoid the risk of brake failure. If the tires are heavily worn from daily driving, check and replace them to ensure strong traction. If the spark plugs are old, replacing them can boost performance. Paying attention to these simple replacements and spending a little money can prevent major repairs and breakdowns later. I think maintenance is an investment in peace of mind.

After using the car for two years, it's time for maintenance to ensure family safety. I will change the engine oil and oil filter to keep the engine running clean. Replacing the air filter and cabin air filter ensures good air quality inside the car, which is beneficial for health. Brake fluid should be changed regularly as its performance declines after two years, which could compromise braking. Check the tires and replace them if they are heavily worn to avoid skidding in rainy conditions. Maintaining these components on time reduces road risks and allows for worry-free travel.
