Preventive Maintenance Tips Every Driver Should Know

As someone who has spent over 35 years in the automotive industry, I’ve seen countless vehicles come through my shops that could have avoided expensive repairs with just a bit of preventive maintenance. Owning three auto repair businesses, I’ve learned one crucial thing: regular maintenance is the key to keeping your vehicle running smoothly and saving you money in the long run. Whether you drive an Asian-manufactured vehicle or something else, these simple tips will help you extend the life of your car and prevent those dreaded breakdowns.

Here’s what every driver should know about preventive maintenance:

1. Keep an Eye on Your Oil (and Don’t Forget the Filter!)

Oil is your engine’s lifeblood. Without it, the engine’s internal parts will overheat and wear out quickly. Most manufacturers recommend an oil change every 5,000 to 7,500 miles, but this can vary depending on your driving habits. For example, frequent short trips or stop-and-go traffic can put extra stress on the engine, meaning you might need to change the oil sooner.

Pro Tip: Don’t just change the oil; make sure to replace the oil filter, too. A clogged filter can cause contaminants to circulate through the engine, leading to long-term damage. If you’re ever in doubt, check your vehicle’s manual or ask a certified technician like the ones at Asian Imports.

2. Check Your Tires Regularly

Tire maintenance is often overlooked but is essential for safety and fuel efficiency. Underinflated tires create more resistance on the road, causing your car to use more fuel, while overinflated tires can lead to premature wear and a rough ride.

At a minimum, check your tire pressure once a month and before long road trips. Most cars have a sticker on the driver’s side door with the recommended PSI (pounds per square inch). While you’re at it, inspect the tread. If it’s looking worn or uneven, it’s time for a rotation—or possibly new tires.

Pro Tip: Use the “penny test” to check your tread depth. Insert a penny into the tread with Lincoln’s head facing down. If you can see all of his head, it’s time to replace those tires.

3. Don’t Forget the Fluids

Your car relies on more than just oil to keep everything running smoothly. Brake fluid, transmission fluid, coolant, and power steering fluid are all critical for the health of your vehicle. Each fluid has its own change intervals, which are usually listed in your owner’s manual, but it’s a good idea to have them checked every time you’re in for an oil change.

Pro Tip: If you notice any leaks, get them checked immediately. Ignoring a slow fluid leak can lead to much bigger (and more expensive) problems down the road.

4. Replace the Air Filter

The engine air filter prevents dust, dirt, and other debris from getting into the engine. A clogged air filter can reduce your engine’s performance, lower fuel efficiency, and even cause the engine to misfire. Most manufacturers recommend changing the air filter every 15,000 to 30,000 miles, but driving in dusty conditions could mean replacing it sooner.

Pro Tip: A dirty air filter doesn’t just hurt your car’s performance—it can also reduce the efficiency of your heating and air conditioning system. Ask your technician to check it during routine maintenance.

5. Don’t Ignore Your Brakes

Your brakes are one of the most critical safety systems in your vehicle. If you hear squeaking, grinding, or notice that the pedal feels soft or spongy, don’t wait to get them checked. These are signs that your brake pads or rotors may be worn and need replacement.

Pro Tip: Even if you don’t hear any noise, have your brakes inspected at least once a year. Regular checks can help catch issues before they become a major safety hazard.

6. Battery Maintenance

A dead battery always seems to happen at the worst possible time. To avoid getting stranded, check your battery’s health regularly. Most batteries last about 3–5 years, but extreme temperatures can shorten that lifespan. If you notice your car is slow to start, it may be a sign that your battery is on its way out.

Pro Tip: Clean off any corrosion around the battery terminals and have the battery tested during regular maintenance visits.

7. Timing Belt and Serpentine Belt Checks

The timing belt (or chain) and serpentine belt are often out of sight and out of mind, but they are vital to your engine’s performance. If a belt breaks, it can cause catastrophic engine damage. Most manufacturers recommend replacing the timing belt every 60,000 to 100,000 miles, depending on the vehicle.

Pro Tip: Pay attention to any unusual noises like squealing or grinding coming from under the hood. These could be signs that a belt is worn and needs replacing.
