Monthly Maintenance Tasks

Taking care of your car doesn’t have to be overwhelming. With just a little time each month, you can keep your vehicle running smoothly and avoid unexpected breakdowns. Here’s a breakdown of five key maintenance tasks that take less than an hour and can save you money and hassle down the road.

Check Tire Pressure and Tread

Your tires are the only thing connecting your car to the road, so keeping them in good shape is critical. In 2023, tire-related crashes claimed the lives of 646 people, many of which could have been avoided with proper care.

Start by checking your tire pressure when the tires are cold – either before driving or after the car has been parked for at least three hours. Your vehicle’s recommended PSI (pounds per square inch) can be found on a sticker inside the driver’s door or in your owner’s manual. Use a tire pressure gauge to check each tire, including the spare. Underinflated tires not only reduce fuel efficiency by about 0.2% per 1 PSI but can also wear out faster, costing you money in the long run. Properly inflated tires can improve gas mileage by up to 3% and extend their lifespan by approximately 4,700 miles.

"Proper tire pressure is the most important part of maintaining your tires. It affects safety, their durability, and your fuel consumption." – NHTSA

Next, check the tread depth using the penny test. Insert a penny into a tread groove with Lincoln’s head upside down. If you can see the top of his head, your tread depth is less than 2/32", and it’s time for new tires. For a more cautious approach, use the quarter test: insert a quarter with Washington’s head facing down. If the top of his head is visible, your tread is below 4/32", and you should consider replacing your tires soon. Uneven wear patterns, such as center or edge wear, may signal overinflation, underinflation, or the need for a wheel alignment.

Check Fluid Levels

Fluids are the lifeblood of your car, keeping its systems running efficiently. A quick inspection each month can prevent major issues.

• Engine Oil: Pull out the dipstick, wipe it clean, reinsert, and check the level. The oil should be amber-colored. If it’s dark or gritty, it’s time for a change. Frequent oil top-offs could indicate a leak that needs professional inspection.
• Brake Fluid: Check the reservoir on level ground with the engine cool. Low fluid levels or a spongy brake pedal should be addressed immediately.
• Coolant: Inspect the coolant reservoir when the engine is cool – never remove the radiator cap when it’s hot. Low coolant can lead to overheating and expensive repairs.
• Power Steering Fluid: If steering feels stiff or you hear squeaks while turning, check the fluid level. Low levels can cause difficulty steering and unusual noises.
• Transmission Fluid: For cars with a transmission dipstick, the fluid should be bright red and smell slightly sweet. Dark or burnt-smelling fluid needs immediate attention.
• Windshield Washer Fluid: Keep this topped off to maintain clear visibility, especially in winter when grime and salt can build up.

Regular fluid checks are simple but crucial for avoiding costly repairs down the line.

Test Battery Health

A dead battery can leave you stranded, so it’s worth taking a few minutes each month to check its health. Inspect the terminals for corrosion and clean them with a wire brush and baking soda solution if needed. Ensure the cables are tightly secured – loose connections can cause starting issues. If you have a multimeter, test the voltage. A healthy battery should read between 12.4 and 12.7 volts when the engine is off. Most car batteries last 3-5 years, so if yours is older or showing signs of weakness, consider having it tested by a professional.

Check Lights and Signals

Faulty lights not only compromise your safety but can also result in fines. Walk around your car to inspect all exterior lights. Test your headlights on both low and high beams, making sure they’re properly aimed. Check brake lights, turn signals, reverse lights, side markers, and license plate lights. If any bulbs are out, replace them immediately to ensure your car is road-ready.

Clean or Replace Air Filters

Air filters play a vital role in your car’s performance and air quality. There are two types to keep an eye on:

• Engine Air Filter: This filter blocks dirt and debris from entering your engine. A clogged filter can lower fuel efficiency, cause rough idling, and even trigger the check engine light. To check, remove the filter and hold it up to the light. If light doesn’t pass through, it’s time for a replacement. Typically, engine air filters should be replaced every 12,000 miles or 12 months, though dusty conditions may require more frequent changes.
• Cabin Air Filter: Located behind the glove box or under the dashboard, this filter cleans the air entering your car’s interior. Replace it if airflow is reduced or there’s a persistent musty odor when using the heat or AC.

Replacing air filters is straightforward and affordable, usually costing $10–$30 per filter. The payoff? Better air quality, improved fuel economy, and reduced engine wear.

Tools and Supplies You Need

Having the right tools and supplies on hand can make monthly car maintenance a smoother and more efficient process. You don’t need a full-blown garage setup – just a few key items that help you get the job done safely and effectively. These essentials directly support the monthly checks outlined earlier, keeping your maintenance routine on track.

Basic Tools for Maintenance

A tire pressure gauge is a must-have for ensuring proper tire pressure, which improves fuel efficiency and prolongs tire life. Digital models, priced between $10 and $25, are easy to read and reliable.

A socket set with sizes ranging from 8 mm to 19 mm is versatile enough for most tasks, such as tightening battery terminals or accessing air filters. Pair this with a set of combination wrenches and screwdrivers (both Phillips and flathead) in various sizes to handle loose connections or remove covers during inspections.

Always keep jumper cables in your car for emergencies. Choose cables that are at least 12 feet long with sturdy clamps for dependable performance. A digital multimeter is another handy tool for checking battery voltage and diagnosing electrical issues.

Other helpful items include disposable nitrile gloves to keep your hands clean, a funnel for spill-free fluid refills, and microfiber cloths for wiping dipsticks or cleaning surfaces. A small flashlight or headlamp is invaluable for working in dimly lit areas under the hood, especially during evening checks.

Store these tools in a compact toolbox to keep everything organized and ready for use. With these basics, you’ll be well-equipped to handle routine maintenance tasks efficiently.

Recommended Supplies

It’s wise to keep a stock of essential fluids: engine oil (as specified in your manual), brake fluid, coolant, power steering fluid, and windshield washer fluid. Check expiration dates periodically, as some fluids can degrade over time.

Having replacement air filters for both the engine and cabin is also practical. Engine air filters typically cost $10–$20, while cabin air filters range from $15–$30. Keeping spares on hand allows you to swap them out as needed without making a special trip to the store.

A spare fuse kit is another space-saving yet critical item. These kits usually include common amperage ratings – 5, 10, 15, 20, and 30 amps. Most vehicles use mini blade fuses, but it’s a good idea to confirm the correct type in your owner’s manual.

For cleaning battery terminals, simple items like baking soda and a wire brush are highly effective. Use a small spray bottle of distilled water to rinse off the cleaning solution afterward.

Other useful supplies include penetrating oil (like WD-40) for loosening stuck bolts and electrical contact cleaner for maintaining battery connections. These items have long shelf lives and can be used for a variety of maintenance tasks beyond your regular monthly routine.

Maintenance Logbook

Along with tools and supplies, a well-organized logbook can simplify routine upkeep. A maintenance logbook turns scattered notes and receipts into a clear record that helps you save money and protect your car’s value. Whether you prefer a physical notebook, a digital spreadsheet, or a smartphone app, keeping detailed records is worth the effort.

Your logbook should include essential details such as vehicle information (make, model, year, VIN), service dates, mileage at service, tasks performed, costs, and service provider details. Record everything from oil changes to your monthly DIY checks. Regular maintenance can improve fuel efficiency by up to 4.1%, and a detailed log helps you track these benefits.

Both digital logs and physical logbooks have their perks. Digital logs often include features like automatic reminders, data analysis, and cloud backups. You can set alerts for monthly maintenance and use the data to identify trends, like changes in fuel consumption. Physical logbooks, on the other hand, are perfect if you prefer handwritten notes and want a record that stays with your car. A simple format with columns for date, mileage, service performed, cost, and notes works well.

Update your log after each task and review it regularly to stay on top of your car’s maintenance needs.
