What needs to be replaced during annual car maintenance?

During annual car maintenance, engine oil and oil filters generally need to be replaced; the most frequent car maintenance task is washing the car; the most important areas to regularly inspect are tire surfaces and pressure, oil level, coolant level, and brake fluid level. Regular car maintenance typically involves replacing: 1. Engine oil and oil filter: Engine oil and oil filters basically need to be replaced during every maintenance service. Car engine oil is generally divided into three types: mineral oil, semi-synthetic oil, and fully synthetic oil, each with different replacement cycles. 2. Coolant: Car coolant not only provides antifreeze protection but also helps cool the engine during operation by dissipating high temperatures. In winter when temperatures are low, coolant prevents low-temperature damage to the engine. Generally, coolant needs to be replaced every three years or 50,000 kilometers. 3. Windshield washer fluid: Windshield washer fluid is mainly used to clean dirt from the windshield and needs to be replenished when empty. During winter use, it is recommended to add antifreeze windshield washer fluid to prevent freezing and damage to the washer fluid reservoir, which could affect normal usage. 4. Cabin air filter: The cabin air filter helps purify incoming air, ensuring clean airflow from the air conditioning system. Generally, it needs to be replaced every 1 to 2 years. 5. Brake fluid: Brake fluid has different characteristics compared to other fluids. It is hygroscopic, meaning it easily absorbs moisture during use. When brake fluid absorbs water, it can form bubbles, leading to softer brakes and longer stopping distances. It is recommended to replace brake fluid every 2 years to prevent braking abnormalities and ensure driving safety.
When doing annual car maintenance, I believe changing the engine oil and oil filter is fundamental. If skipped, engine wear accelerates, and you’ll feel noticeable sluggishness when driving. The air filter should also be replaced yearly, especially for city driving where dust can clog the intake, reducing engine efficiency. The cabin air filter is a must-change item for me, particularly before seasonal transitions, to ensure odor-free airflow and maintain comfortable air quality inside the car—especially important for families with elderly members. Brake fluid doesn’t need annual replacement, but it’s wise to check its level and condition yearly; brake failure would be extremely dangerous. Coolant should follow the manufacturer’s recommendations, and in northern winters, it must also prevent freezing to protect the engine. Overall, sticking to the owner’s manual is the most hassle-free approach. Don’t skimp on these small replacements to save money, or you’ll face much higher repair costs later.
