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

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.

The sedan I bought five years ago is now at a critical maintenance period. The top priority is changing the engine oil and oil filter—don’t underestimate them, as accumulated impurities can accelerate engine wear. Tire wear also needs close attention; after five years, the rubber is likely aged or worn down, so check the tread depth and tire pressure to avoid dangerous skidding in rainy conditions. Brake pad wear is another key point—I just replaced mine last month, and the ride has become much quieter. The brake fluid should also be replaced to ensure system responsiveness. Don’t overlook the coolant and spark plugs either—coolant prevents corrosion and protects the engine, while spark plugs affect ignition efficiency, impacting fuel economy. Additionally, inspect the cabin air filter and wiper blades—these small components directly impact comfort. Investing in overall maintenance now can save you from costly repairs later, ensuring safety and peace of mind.

As a parent who frequently shuttles children, I pay special attention to the safety of a five-year car maintenance. Replacing brake system components is the top priority, including brake pads, rotors, and fluid—don’t wait until they squeak, as it concerns the lives of your entire family. Check tire pressure and alignment; after five years, rubber may crack, posing a high risk of blowouts at high speeds. Regularly change engine oil and filters to maintain lubrication, and don’t forget to inspect the cooling system fluid—overheating and breaking down roadside would be troublesome. Spark plugs affect smooth starts, and aging batteries should be tested; once, I was frantic when the car wouldn’t start in winter. Simple replacements like wipers and filters can be done yourself, saving money and boosting driving confidence.

For five years of car ownership aiming to save on maintenance, prioritize changing the engine oil and oil filter, and act as soon as the mileage hits the mark—it's the most cost-effective way to extend engine life. Only replace tires when they're severely worn, and check the tread depth to save money. Follow the manual for spark plugs, coolant, and brake fluid—no need to rush replacements; early self-checks can prevent major repairs. Just test the voltage for an aging battery, and replace the cabin air filter yourself to improve airflow efficiency. Keep it simple overall, focusing on saving time and effort.
