What Needs to Be Replaced and Maintained for a Five-Year-Old Car?

[DelClara]

For a five-year-old car, the items that need to be replaced and maintained include engine oil and oil filter, air filter, windshield washer fluid, antifreeze, and air conditioning refrigerant. Detailed descriptions are as follows: The replacement of engine oil and oil filter is primarily for the maintenance of the lubrication system. These two items are the most basic yet the most important in maintenance. The function of the oil filter is to remove various impurities from the engine oil, ensuring the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. The air filter is related to whether the engine breathes smoothly, and the cabin air filter affects the air quality inside the car. Both are quite important. During maintenance, they should be replaced according to the intervals specified in the maintenance manual. Windshield washer fluid, antifreeze, and air conditioning refrigerant are also crucial. Windshield washer fluid is actually related to safety; it must be replenished promptly when running low. In cold regions, it is essential to use antifreeze that can withstand low temperatures, meaning its freezing point should be lower than the local temperature. Otherwise, the washer fluid may freeze and potentially crack the reservoir. Air conditioning refrigerant should be added in the correct amount if the cooling effect is poor and it is found to be due to a lack of refrigerant after inspection.
