When you start driving a used car for over 5 years, it's essentially time for serious maintenance. In other words, just like people, cars age too.

Even if the body looks fine, the interior starts sending signals one by one, so I will share tips on how to keep a used car over 5 years mainly focused on maintenance.

Engine Oil and Filter

It's like blood circulation for a person. If you don't change the engine oil on time, internal friction increases and can eventually lead to major breakdowns. It's generally recommended to change it every 5,000 to 7,000 miles, but for an older car, it's better to change it every 5,000 miles. The engine oil filter should also be replaced for it to be effective. Seeing a friend who neglected this and ended up with a huge repair bill makes me realize how much of a difference small maintenance can make.

Timing Belt and Chain Check

Once you pass the 5-year mark, it's time to consider replacing the timing belt. This acts like the rhythm of the heart; if it breaks, the engine can be severely damaged. It's generally recommended to replace it between 60,000 and 100,000 miles, but for a used car, you must check when the previous owner replaced it. If there's no record, it's better to just replace it for peace of mind.

Brake Pads and Discs

Brakes are synonymous with safety. If you think, 'It should be fine for now,' and suddenly hear squeaking sounds while stopping, it's already too late. Regularly check the thickness of the pads, and if the discs have severe grooves, it's better to replace them together. Holding off on replacement to save costs is like gambling with your life.

Tire Inspection and Rotation

Tires are the only contact point between the car and the road. If they are worn out or the air pressure is inconsistent, fuel efficiency drops and the risk of accidents increases. I check the tire pressure every season and rotate them every 6 months. Just doing that can extend their lifespan by over a year.

Battery Maintenance

Not being able to start the car in the dead of winter is truly a nightmare. The lifespan of a battery is about 3 to 5 years, so for a car over 5 years old, it's wise to consider replacing it soon. Many repair shops offer free battery voltage tests, so it's smart to check and prepare in advance.

Coolant and Radiator

Coolant is an essential element that keeps the engine heat in check. If the coolant is low or old, it can lead to corrosion or overheating. This is the part that causes the most stress during long drives in summer, so checking the coolant level and cleaning the radiator is a must.

Suspension and Underbody Inspection

Used cars especially have issues with the underbody. If the shock absorbers weaken, the car bounces, and if the bushings wear out, it leads to rattling. This increases driver fatigue and gives the feeling that 'the car is getting old.' Regularly checking the underbody at a repair shop with a lift is the key to longevity.

Ultimately, to keep a used car for over 5 years, the answer is to develop the habit of 'taking care of it before it breaks down.'

If you manage basic items like engine oil, brakes, and tires well, the car can run without issues for over 10 years.

As a man who loves cars, I realize that maintenance is more important than washing the car.

It's not just about looking shiny on the outside; it needs to be healthy on the inside to truly last long.
