What Items Need to Be Replaced During Car Maintenance?
2 Answers
Car maintenance items that require replacement include engine oil, oil filter, coolant, windshield washer fluid, etc. Below is the relevant information: 1. Engine Oil and Oil Filter: Engine oil and oil filters generally need to be replaced during every maintenance service. Car engine oil is typically divided into three types: mineral oil, semi-synthetic oil, and full-synthetic oil. Different oils have different replacement intervals. Generally, mineral oil should be replaced every 5,000 kilometers or six months, semi-synthetic oil every 7,000 kilometers or six months, and full-synthetic oil every 10,000 kilometers or one year. During daily driving, if the driving environment is harsh, the oil replacement interval may vary. 2. Coolant: Car coolant not only provides antifreeze protection but also helps cool the engine during operation. In winter, when temperatures are low, coolant prevents low-temperature damage to the engine. Typically, coolant needs to be replaced every three years or 50,000 kilometers. When replacing coolant, note that different brands and types of coolant should not be mixed, as this can lead to reduced performance. 3. Windshield Washer Fluid: Windshield washer fluid is primarily used to clean dirt from the windshield and should be refilled when depleted. During winter, it is recommended to use antifreeze windshield washer fluid to prevent the washer fluid reservoir from freezing and affecting normal use.
As a seasoned driver with over two decades of experience, I believe the most frequently replaced items in car maintenance are engine oil and oil filters. They typically need to be changed every 5,000 to 10,000 kilometers; otherwise, the engine will suffer significant wear, leading to rough operation and a humming noise. Air filters are also crucial—replace them when they're dirty to prevent dust from affecting combustion efficiency. Spark plugs should be inspected every 30,000 kilometers and replaced if they fail to ignite. Transmission fluid should be changed approximately every 40,000 kilometers, especially for automatic vehicles, to prevent worsening gear-shift jerks. Coolant should be replaced every two years to ensure the car doesn't overheat in summer or freeze in winter. Tires should be replaced once the tread wears down to the wear indicators, ensuring good traction in rain or snow. Brake pads must be monitored for thickness and replaced immediately when worn down, as they are critical for safety. Regular replacement of these components can extend a car's lifespan by over a decade while minimizing major issues, saving both money and hassle.
