DIY Car Maintenance: What You Can Do at Home

Paying for routine automotive maintenance can really add up over the years. Many simple service jobs are well within the abilities of the average car owner with some basic tools and guidance. Learning to do these tasks yourself keeps more money in your pocket. To that end, here are a few DIY car maintenance items that are totally doable at home.

Battery Care

Your car’s battery provides the critical power to start the engine and run electrical systems. Yet batteries eventually weaken and fail, usually after 3-5 years of service. Instead of buying a new battery every time, try to maximize its lifespan through proper care. The experts over at Clore Automotive recommend using a battery charger every few months to top off charge levels. Clean corrosion from cable connections using a stiff brush and baking soda solution. And during winter, use an insulating jacket to help the battery retain heat for better cold cranking.

Light Bulb Replacement

Does a warning light on your dash indicate that a burned-out bulb needs to be replaced? Don’t overpay a repair shop for this simple task. Most exterior bulbs are easy to access and switch out as a DIY project. Just locate the bulb, turn it counterclockwise to release, then replace it with a new one. Check your owner’s manual for the proper bulb type since these vary between makes/models. Avoid overpriced dealer bulbs by buying affordable aftermarket versions.

Windshield Wiper Swaps

After enduring a year or two of harsh weather, windshield wiper blades will naturally deteriorate and streak. Replacing them yourself avoids an unnecessary service charge. Most wiper arms have a simple locking tab you depress to slide off the old blade. Just line up the new one and press it firmly into the arm until it locks in place. Check the owner’s manual for compatible sizes and blade types before ordering replacements.

Air Filter Changes

Both engine air filters and cabin air filters need periodic replacement to keep air flowing freely. Replacing these simple filter elements freshens airflow and prevents expensive internal damage from contaminants over time. Locate the filters (usually with housing boxes mounted inside or under the hood) and simply pop out the old one. Install new filters with the proper fit and you are good to go for another year.

Power Steering Fluid Top-Offs  

If your steering feels stiff lately or is making whining sounds, the likely cause is low power steering fluid. Topping this off can often restore normal operation without a need for other repairs. Just locate the reservoir tank under the hood, wipe off the filler cap area, then pour in fresh power steering fluid until it reaches the proper “Full” level line. Do not let the reservoir go dry or you’ll need to deal with expensive air purges.

Coolant System Flushes

Your car’s coolant performs a vital role in regulating engine temperature and preventing overheating. But over time, this liquid becomes contaminated and loses effectiveness. Before serious problems develop, you can do a DIY cooling system flush to swap out the old fluid. Connect a pump to circulate fresh coolant, while draining all the old, contaminated fluid from the radiator and engine block. Though messy, a proper flush every few years prolongs system life.


With a few basic tools and supplies, the average driver is perfectly capable of tackling many routine automotive maintenance projects themselves. Do-it-yourself tasks like battery care, light bulb swaps, air filter replacements and more are well within reach. Not only do you save labor costs, but maintaining your car properly extends its longevity and reliability. All it takes is a little effort and know-how.
