Let this monthly vehicle maintenance checklist help guide you through the essentials, so you can keep your car in top operating condition.
On average, out of a total of 284 million vehicles operating on U.S. roads every day, roughly 277 million are ICE-driven. Of that total, only about 16.4% are regularly maintained by DIY folks working on their own cars and trucks.
There are a number of advantages in this sector of the driving public, including regular reductions of maintenance cost, the value-add of extending your vehicle’s life-cycle, and the enhanced personal satisfaction created by doing your own work, on your own vehicle.
To help more daily drivers get into the DIY swing, the first step usually involves the production of some kind of checklist that can be used to identify and illuminate basic maintenance needs. Consequently, we’ve built just such a list to help get you started. Check it out below.
The Vehicle & The Walk Around
This checklist is based on a physical walk-around process. Part of executing efficient DIY auto maintenance relates to establishing a routine. In this case, we suggest that you start this exercise at the front, then circle the vehicle from right to left.
Exterior
Visually inspecting the exterior of a vehicle, you can identify any damage or wear and tear that could potentially compromise safety. For example, you can identify maintenance issues that need to be addressed, such as rust, peeling paint or damage to the body. This in turn, helps maintain its resale value.
In addition to looking at the body of the vehicle, be sure to inspect:
Wheels are critical components of a vehicle's suspension system and are responsible for supporting the weight of the vehicle. Inspecting the wheels regularly can help identify any issues that could compromise safety, such as cracks or bends.
Tires are the only point of contact between the vehicle and the road. Their condition can significantly impact the safety of the vehicle. Inspecting the tires regularly can help identify any issues that could compromise their ability to grip the road, such as worn treads, bulges or cracks. Also keep a sharp eye out for signs of uneven wear, as this could signify improper alignment or inflation, or even worn-out suspension components.
Under the Hood
Inspecting the engine compartment also helps identify any safety or performance issues, such as leaks, cracks or worn-out belts. Pay special attention to:
Compartment Vents. Engine compartment vents are designed to allow dynamic airflow through the engine compartment, thereby helping to cool the engine. If the vents are blocked or clogged with debris, they can restrict airflow and cause the engine to overheat.
Clamps And Fittings. Clamps and fittings are essential components and hold various hoses, pipes and wiring systems in place. Regularly inspecting them helps identify issues that could compromise primary mechanical and electrical functions due to debris, unusual wear or physical damage. Addressing these issues promptly can help prevent more serious problems from developing, and extend the lifespan of primary components.
Hose Elasticity. Hoses in a vehicle's engine compartment are essential components that transport fluids and air between different parts of the engine. Regularly inspecting their elasticity can help identify any issues that could compromise their function, such as cracks, leaks or stiffness.
Electrical Harnesses. Electrical harnesses are essential components in a vehicle's electrical system, responsible for connecting various electrical components in the engine compartment. Regular inspection helps identify issues that can compromise functionality, such as frayed or damaged wiring or corroded connections. Additionally, electrical issues can pose safety hazards which can lead to the potential of reduced engine performance or even accidents.
The airbox is responsible for housing a filter that allows air to enter the engine. Regularly inspecting the airbox for cracks or deformations can avoid limitations in engine functionality.
Intake Hose. The airbox intake hose brings clean air into the engine through the air filter. Regularly inspecting the intake hose can help identify any issues that could compromise its function, such as cracks, holes or tears.
Engine Air Filter. The air filter prevents dirt, dust and other contaminants from entering the engine and damaging its internal components. If the air filter is clogged or dirty, it can reduce the airflow into the engine, which can cause decreases in power and fuel efficiency.
Fluid Levels. Various vehicle fluids including engine oil, coolant, brake fluid, power steering fluid and transmission fluid, are critical to keeping the vehicle's systems functioning properly. Low fluid levels can cause excessive wear and tear on critical components, such as internal engine or transmission components.
Liquid Reservoirs. Each fluid reservoir has a specific level necessary to ensure that the engine functions properly. Inspecting for cracks or deformations in these reservoirs helps identify the potential of larger fluid failures.
Interior
Next stop on the monthly vehicle maintenance checklist is inside the cabin. Performing a visual inspection of a vehicle’s interior may seem minor, but it’s actually a very important step in ensuring the safety, longevity and overall value of the vehicle. Here are the items you want to pay close attention to:
Interior Vents. Interior vehicle vents are responsible for distributing air throughout the cabin, including heating and cooling. Inspecting the vents helps ensure that they are free of obstructions and air is flowing properly, while maintaining proper temperatures.
Cabin Air Filter. The cabin air filter blocks pollen, dirt and other harmful particles from wafting into the cabin. Inspecting the cabin air filter ensures that interior air is properly clean, and you won’t be breathing in any pollutants.
Interior Technologies. Alert lights, GPS, infotainment systems, ADAS features and other interior technologies are essential for providing information to the driver and ensuring the safe operation of the vehicle. Inspect these technologies to ensure they are functioning correctly and providing accurate information.
Seat belts. A crucial safety feature in a vehicle, seat belts are designed to protect occupants in the event of a collision. Inspect them closely, looking for any signs of fraying, cuts or visible damage. Check that the latch plate and buckle are functioning properly, and that the seat belt locks into place when you pull it tightly across your person.
Interior/Exterior Gaskets. Gaskets are used to create rubberized seals between two surfaces, such as door edges and the body of the vehicle. Inspecting gaskets helps ensure that they are not worn, split or damaged, which in turn can cause leaks leading to damage and expensive repairs.
Interior/Exterior Glass Surfaces. Clean glass surfaces are essential for maintaining visibility while driving. Inspect the windshield and all windows, looking for chips, scratches or glass crazing that can reduce visibility and compromise safety.
From headlights, taillights and brake lights to turn signals, auxiliary lights and even dome lights, proper illumination is key to safe and enjoyable driving experiences. Test every switch, knob and button to ensure all lights are not only working, but also shining with the appropriate level of brightness and color hue.
It goes without saying that stopping power is critical to vehicle safety and performance. Regular inspection of the brake system will help identify issues that can compromise your vehicle’s ability to stop effectively. To test the system, simply drive the vehicle at a slow speed and apply the brakes firmly. Listen for any unusual noises, such as squealing or grinding, and pay attention to the pedal feel. It should be firm and responsive. Remember to perform this testing in a safe location, like an empty parking lot or a quiet road.
So, there you go! By following this checklist, you can help ensure your vehicle stays in good condition and also avoid more costly repairs down the road. Taking the time to perform these monthly vehicle maintenance tasks now might be a small investment, but we promise it will pay off in the long run.
