What Generally Needs to Be Replaced in Car Maintenance

[DelSkylar]

Car maintenance requires the replacement of the following two items: 1. The first must-change items during maintenance are engine oil and the air conditioning filter. 2. At the interval of two years or 40,000 kilometers, it is recommended to replace the transmission fluid and clean the throttle body every 20,000 kilometers. Additional information: 1. Car maintenance, also known as vehicle servicing, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. It mainly includes the maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, and extend the service life. 2. Not all car models are suitable for owners to change the engine oil themselves, but they can learn to check the oil dipstick to determine if the oil needs replacement. Additionally, the oil filter must be replaced when changing the engine oil.

When I first bought my car, I didn't really understand what needed to be replaced during maintenance. I went to the 4S dealership and asked around before figuring it out. Basically, I change the engine oil and oil filter every time—these two are especially important as they prevent engine wear and rust. The air filter also needs to be replaced regularly; otherwise, dust buildup can affect the engine's 'breathing.' When the tires wear down significantly, they need to be replaced, and old windshield wipers that don't clear water properly should also be swapped out. Brake pads and brake fluid should be checked often—if not replaced on time, the brakes won't work well. Once, I neglected this and almost got into trouble. Engine oil is usually changed every 5,000 kilometers, but checking the manual is the most accurate way to know. In short, don't slack on maintenance—it extends the car's lifespan, saves money, and keeps you safe.

With over 30 years of driving experience, I know vehicle maintenance inside out. Engine oil and oil filter are must-change items, along with the air filter – a clogged one robs your car of power. Spark plugs wear out quickly and need replacement every few tens of thousands of kilometers. Don’t overlook brake fluid and transmission fluid either; degraded lubrication from aged fluids is hazardous. Tires are wear items – replace them immediately when treads get shallow to maintain proper grip. Cabin air filters shouldn’t be neglected either, or musty airflow will affect health. Regular maintenance prevents major overhauls and extends vehicle lifespan. I recommend keeping a maintenance logbook to record service dates – developing this habit saves money and brings peace of mind.

As a full-time mom, my top priority is ensuring my car doesn't break down and delay picking up the kids. During every maintenance, I always change the engine oil and oil filter first—simple yet crucial to prevent engine damage. I also replace the air filter frequently to reduce dust and keep the cabin air fresh. Worn-out wiper blades that don't clear properly get replaced immediately—safety comes first in rainy conditions. After checking tire wear, I replace them if needed, and I always follow professional advice on replacing brake pads. Changing these small components more often offers great value, spending a little to avoid hefty repair bills.

As an eco-friendly car enthusiast, maintaining a hybrid vehicle is similar. Regularly changing engine oil and air filters can reduce exhaust emissions, making it greener. Worn-out spark plugs affecting efficiency must be replaced, and deteriorated brake fluid that may reduce braking performance should also be promptly changed. Wipers and tires, as wear-prone parts, should be replaced when worn to ensure fuel efficiency and safety. Opting for environmentally certified products, such as low-volatility engine oil, is more eco-friendly and enhances vehicle performance.

In my spare time, I love tinkering with cars and doing maintenance myself, replacing parts by hand. Changing the oil and oil filter most frequently can prevent engine damage, while replacing the air filter ensures smooth engine breathing. Worn-out spark plugs are quickly swapped to improve ignition efficiency, and coolant and transmission fluid are changed regularly to maintain lubrication. When replacing tires, I opt for wear-resistant types to extend their lifespan, and aging brake pads are replaced to ensure reliable braking. Doing it myself saves money and builds skills, keeping the car running smoothly and worry-free.
