Maintenance is a fundamental discipline in automotive care, applicable to daily drivers and project cars. Routine inspections separate preventive management from reactive repairs, allowing you to address issues before they fail.
To ensure consistency, make a structured checklist and stick to a service schedule. Here are eight essential action items for your long-term car maintenance checklist.
1. Measure fluid levels
Fluids help your car’s long-term health by cooling, lubricating and providing hydraulic power. Once a month, set aside time to check these components. The primary fluids in your vehicle include the following products:
- Engine oil
- Coolant
- Transmission fluid
- Brake fluid
- Power steering fluid
- Windshield wiper fluid
2. Maintain the battery
Batteries require clean connections to start reliably, so check the terminals when you change the oil. Lead sulfate may appear on the surface and prevent the starter from receiving full power. If you see a white, powdery substance, it is time to clean. You can scrub the battery with a baking soda and water paste, even if your only tool is a toothbrush.
3. Test the brake system
The brakes rely on hydraulics to slow down your heavy car, and they contain several components that require regular maintenance. Start by inspecting the brake fluid and ensuring it is between the minimum and maximum lines. If it seems low, you may have a leaky brake system or worn pads. Murky coloring means it is time for a replacement.
The brake system can also indicate its health through sound. Test by listening for screeching and squealing. Worn brakes make a high-pitched noise because metal is scraping against the rotor, indicating it is time for service. Vibrations are another issue, as they reveal the rotors have become uneven. You can visually inspect the brakes by checking the thickness of the pads.
4. Gauge tire health
Tires are your car’s only contact with the road, so they must be in great shape. Ensure they receive the proper attention by regularly checking tire pressure, especially during extreme weather conditions. Tires lose up to 2 pounds of pressure for every 10-degree temperature change. You can automate the task by installing a tire pressure monitoring system in your vehicle.
Tread depth is another critical indicator of tire health. Worn tread leads to less grip for the tires, which can be dangerous on slick roads. You can test this measurement by sticking an American penny inside the grooves. Place the coin upside down and test how much of Abraham Lincoln you can see. If you can see the top of his head, the tread has become worn.
5. Tend to the undercarriage
The exterior and parts under the hood are more noticeable because they are visible. However, you should still take the time to maintain the undercarriage’s structural integrity. Washing is a smart strategy to keep your entire car clean, especially in hard-to-reach places. Experts recommend washing at least twice monthly and treating surfaces with wax.
While regular washes tackle dirt and animal droppings, they tackle a larger problem — rust. Iron oxide forms on the car’s metal components once they react with oxygen and water. Focus on the frame and exhaust, as rust is most likely to form in these areas. You may need more frequent checks if you live near the ocean or on roads treated with salt.
6. Inspect the air filter
Just as you should replace the air filter in your home’s HVAC, give your engine the same treatment. This component functions like your lungs, requiring optimal performance for long-term health. Over time, your engine’s air filter becomes clogged with dust and other unwanted particles. Visually inspect it at least once a year or every 30,000 miles for excessive dirt buildup.
Although it is a less frequent task, there are a few signs that indicate you may need to change the engine filter. For example, your vehicle may accelerate more slowly or get a lower fuel economy. Listen for strange noises when you crank the engine, as misfirings could be an indicator. Your car may illuminate the check engine light if the air and fuel mix is suboptimal.
7. Assess the belts and hoses
Belts and hoses are overlooked aspects of car maintenance. These components transfer power from the engine to the alternator and power steering, so any issues must be addressed promptly. Before inspection, turn off the car and let the engine cool completely. For safety purposes, it is best to wait and reduce the risk of burns.
Belt inspections should begin by checking for cracking and glazing. If the cracks are close together, it may be time for a replacement. Hoses transport coolant to the radiator and heater hoses, adding to their importance. Check for brittleness and hardness, which indicate the hose is close to cracking. Conversely, softness suggests it could be deteriorating internally.
8. Test the wiper blades
Wiper blades are another underrated car maintenance task, as they are less complex than the engine or tires. However, they still warrant your attention due to the safety implications. Windshield wipers are your first defense against rain, snow and sleet, so they deserve a spot on your maintenance checklist. Worn blades can smear debris and reduce visibility.
You can audibly test the wipers while driving by listening to the sound they make as they move. If they chatter or squeak, there may be a hardened rubber blade or a bent wiper frame. Newer blades should be soft instead of brittle, so check for hardness. Cracked and split wipers have difficulty touching the windshield, making cleaning more challenging. Visually inspect these components every six months, especially as the seasons change.
Mastering your automotive maintenance checklist
Routine care extends the life of your vehicle and is critical to safety. Well-functioning brake systems, tire treads and belts help you control the car and respond to changing road conditions. Drivers also financially benefit because their low-cost tasks defend against expensive repairs. Investing time and resources now means you are protecting your car’s long-term value and maximizing fuel efficiency.
