- Belts & Hoses: Inspect for cracks, fraying, or stiffness. Replace if necessary.
- Wipers & Lights: Test wipers for streaking and lights for proper function.
These checks take about 30 minutes and require basic tools like a tire pressure gauge, flashlight, and multimeter. By catching problems early, you can save time, money, and avoid unexpected breakdowns.
What To Check On Your Car Weekly & Monthly
Engine Oil and Fluid Levels
Taking a few minutes each month to check your engine oil and fluid levels can save you from costly repairs down the road. These simple checks are a key step in keeping your vehicle running smoothly.
Checking Engine Oil
Engine oil plays a crucial role in lubricating the engine’s moving parts and preventing overheating. Without enough oil, friction between metal components can cause severe damage. To check your oil, start with a cold engine parked on level ground for about 10 minutes. Pull out the dipstick, wipe it clean, reinsert it fully, and then remove it again to check the level. The oil should be between the minimum and maximum marks – never let it drop below the minimum.
Pay attention to the oil’s appearance. Fresh oil is clear and fluid, while oil that’s dark, thick, or smells burnt may need to be replaced. If the level is close to the minimum, add oil carefully, staying below the maximum mark to avoid damaging seals and gaskets.
Once you’re done with the engine oil, take time to inspect other critical fluids to ensure everything is in good shape.
Inspecting Other Fluids
Your car relies on several other fluids, each serving a specific purpose:
- Coolant: This keeps your engine from overheating. When the engine is cool, check that the coolant is clear and brightly colored (typically green, orange, or pink). Corrosion or rust around the cap could mean the coolant’s protective properties are wearing out.
- Brake Fluid: Essential for safe braking, the fluid should be clear to light amber. If it’s dark or contaminated, replace it immediately. Low brake fluid can cause a spongy pedal feel or longer stopping distances.
- Transmission Fluid: Check this with the engine running and warm. It should be bright red with a sweet smell. If it’s dark or smells burnt, it’s time for service.
- Power Steering Fluid: This fluid helps with smooth steering. Low levels might cause whining noises when turning or make steering feel stiff and unresponsive.
Keep an eye out for puddles under your car. Different fluids leave telltale stains – transmission fluid is usually red, coolant can be green or orange, and oil often appears as dark brown or black spots.
Tools and Safety Tips
Before you begin, gather a few basic tools: clean cloths, a small funnel, disposable gloves, and a flashlight for better visibility in dimly lit areas. Always check fluids with the engine cool and the car parked on level ground.
Pay attention to dashboard warning lights, such as the check engine light, oil pressure light, or temperature gauge. These can often signal low fluid levels or other issues that need immediate attention. Similarly, don’t ignore unusual smells, especially burning odors near the transmission, as these could indicate internal damage from excessive heat.
Store extra fluids in a cool, dry place, away from children and pets. When it’s time to dispose of used fluids, take them to a designated collection center to ensure proper handling and environmental safety.
Tire Pressure and Condition
Your tires are the only part of your car that touches the road, which makes keeping them in good shape essential for safety, fuel economy, and durability. A quick monthly check can go a long way in preventing costly repairs and ensuring your vehicle runs smoothly.
Checking Tire Pressure
Keeping your tires at the right pressure is a straightforward but important habit. It not only improves fuel efficiency but also enhances handling and extends the life of your tires. Even slight changes in pressure can impact how your car performs.
To get started, you’ll need a tire pressure gauge, an air compressor (or air chuck), and functioning valve caps. The recommended tire pressure for your car is usually printed on a sticker inside the driver’s door jamb or noted in the owner’s manual. Don’t rely on the maximum pressure listed on the tire’s sidewall – that’s not the ideal level for regular driving.
Always check tire pressure when the tires are cold, either before driving or at least three hours after your last trip. Locate the valve stem on each tire and remove its cap by twisting it counterclockwise. If the cap is stuck, pliers can help loosen it, and you should replace damaged caps.
Firmly press the gauge onto the valve stem and wait until the hissing sound stops to get an accurate reading. If the pressure is too low, inflate the tire using an air compressor. If it’s too high, let some air out until you hit the recommended level. Even if your car has a Tire Pressure Monitoring System (TPMS), use a gauge for precise readings. Aim to check your tire pressure weekly or at least once a month, and make it a habit to check when you refuel.
Inspecting Tread and Damage
Tire pressure isn’t the only thing to keep an eye on – tread wear and damage can tell you a lot about your tires’ condition. Over-inflated tires often show extra wear in the center of the tread, while under-inflated tires tend to wear down more on the edges. Uneven wear patterns or consistent air loss could point to problems like punctures or valve stem leaks.
Tire Maintenance Tips
Temperature changes can cause tire pressure to fluctuate. As the weather shifts, adjust your tire pressure to match the manufacturer’s recommendations. Doing so ensures your tires perform reliably and keeps your car operating safely and efficiently.
Brake System Checks
Your brake system is one of the most important safety features of your vehicle. Regularly inspecting it – ideally once a month – can help you avoid dangerous failures and costly repairs.
Brake Pad and Rotor Inspection
Take a look at your brake pads through the wheel spokes. If the friction material looks worn down or if the metal backing is touching the rotor, it’s time for a replacement. Uneven wear on the pads could mean there’s a sticking caliper or uneven pressure in the system.
Rotors should feel smooth to the touch. If you notice deep grooves, cracks, or any signs of warping, don’t delay – have them repaired or replaced immediately.
Brake Fluid Monitoring
Find the clear brake fluid reservoir under the hood. The fluid level should stay between the minimum and maximum lines marked on the container. Fresh brake fluid is typically clear or light amber in color. If it looks dark or dirty, it could mean there’s moisture in the system or another issue.
Check around the reservoir and along the brake lines for leaks. Any sign of leakage should be addressed by a professional right away. After confirming the fluid level, pay attention to how your brakes feel – any changes in performance could signal a deeper problem.
Warning Signs of Brake Problems
Brake issues often give you early warning signs. Once you’ve checked the fluid levels and looked for leaks, keep an eye (and ear) out for performance changes.
- Squealing or grinding noises: These usually mean the brake pads are worn out.
- A soft or spongy brake pedal: This could indicate air in the brake lines or low fluid levels.
- A hard brake pedal: This might point to a problem with the brake booster or vacuum system.
- Pulling to one side or steering wheel vibrations: These are often caused by warped rotors or uneven pad wear.
- Longer stopping distances: This suggests your brakes are losing efficiency.
Finally, don’t ignore the brake warning light on your dashboard – it’s often a sign of a serious hydraulic or system issue that needs immediate attention.
Battery and Electrical System Checks
Your car’s electrical system is the backbone of everything from starting the engine to powering the headlights. A dead battery or a faulty connection can leave you stranded, but performing monthly checks can help you spot potential issues before they turn into emergencies.
Battery Terminal Inspection
Pop the hood and locate your car’s battery. Take a close look at the metal terminals – if you see any colored powder or crusty buildup, that’s corrosion. Corrosion disrupts electrical flow and can stop your car from starting.
If you notice corrosion, disconnect the cables, starting with the negative one (marked with a minus sign). Then, disconnect the positive cable. Mix a tablespoon of baking soda with a cup of water and use an old toothbrush to scrub the buildup away. Rinse thoroughly, dry the area, and reconnect the cables – positive first, then negative.
Make sure the cable connections are tight and secure. Loose connections can cause starting problems or electrical glitches. If the cables wiggle when touched, tighten them using a wrench. Also, inspect the cable insulation for any cracks or fraying, as exposed wires can lead to shorts or sparks.
Once your terminals are clean and secure, move on to testing your battery’s voltage.
Voltage Testing with a Multimeter
To check your battery’s health, grab a digital multimeter. With the engine off, place the red probe on the positive terminal and the black probe on the negative terminal.
A healthy battery should read between 12.4 and 12.7 volts when the engine is off. If it’s below 12.4 volts, your battery might be losing its ability to hold a charge. Now, start the engine and test again – this time, you should see a reading between 13.5 and 14.5 volts, which indicates the alternator is working properly.
If your readings are consistently below 12 volts when the engine is off, or the voltage doesn’t hit 13.5 volts when running, you could be dealing with battery or alternator issues. These tests can give you a heads-up before your car refuses to start.
Once the battery voltage is confirmed, take a moment to check your vehicle’s lights.
Light and Indicator Checks
Every month, do a quick walk-around to inspect all your exterior lights. Turn on the headlights and test both the low and high beams. Press the brake pedal to ensure both brake lights illuminate. Activate your turn signals and hazard lights to confirm they work on all four corners.
Don’t skip the reverse lights – put the car in reverse and check that they light up. Burned-out bulbs aren’t just inconvenient; they’re a safety risk and could even result in a traffic ticket.
Inside the car, scan the dashboard for any warning lights that shouldn’t be there. Pay special attention to the battery warning light, as it signals charging system issues that need immediate attention. If your dashboard lights dim when you turn on accessories like the air conditioning or radio, it could point to a weak battery or failing alternator.
Lastly, test other electrical components like the horn, windshield wipers, and power windows. These rely on your car’s electrical system and can indicate deeper issues if they’re not functioning properly.

Belts, Hoses, and Wipers
In addition to checking fluids and tires, it’s crucial to inspect other key components like belts, hoses, and wipers to keep your vehicle running smoothly and reliably.
Your car’s belts and hoses may not get much attention, but they play a critical role in keeping everything functioning. A broken belt can cause essential systems to fail, while a damaged radiator hose can lead to a complete loss of coolant. Regular monthly checks can help you spot potential problems before they escalate.
Belt and Hose Inspection
Always inspect belts and hoses when the engine is completely cool – never attempt this on a hot engine. Once the engine is cool, open the hood and locate the serpentine belt, which powers vital systems like the alternator, power steering pump, air conditioning compressor, and water pump.
Examine the serpentine belt carefully. Look for cracks, fraying, glazing, or exposed reinforcing cords. If the belt feels stiff or shows any irregularities, it’s time for a replacement. Also, pay attention to unusual noises like high-pitched whines or chirping, as well as engine vibrations – these could signal belt tension issues.
A properly functioning belt should feel smooth and flexible. If it’s hard, brittle, or shows reinforcing cords, it’s worn out and needs to be replaced.
Next, check the hoses. Gently squeeze each one to assess its condition. Healthy hoses should feel firm but flexible. Soft, mushy areas or rock-hard spots indicate deterioration.
Inspect hoses for visible signs of trouble, such as cracks, bulges, collapsed sections, or oil contamination. Even tiny cracks that haven’t started leaking yet can eventually lead to major coolant loss. High under-hood temperatures, especially during summer, can speed up the breakdown of rubber, so keep an eye out for small cracks that suggest internal wear.
Wiper Blade Maintenance
Taking a few minutes each month to check your wiper blades can prevent visibility issues that might compromise your safety.
Lift each wiper away from the windshield and inspect the rubber blade for nicks, tears, or rough patches. Pay close attention to cracking or splitting, particularly at the ends where the rubber experiences the most stress.
Check how the blade sits against the windshield. A properly functioning wiper blade should maintain even contact along its entire length. If you notice gaps or hear chattering during operation, the rubber may have hardened over time.
Test your wipers on a clean, wet windshield. They should move smoothly without leaving streaks, skipping areas, or making excessive noise. If streaking persists even after cleaning, the rubber has likely lost its flexibility.
Don’t forget about the rear wiper if your vehicle has one. Rear wipers often wear out faster due to less frequent use and exposure to dirt and grime.
Replace your wiper blades every 6 to 12 months, or sooner if they show signs of wear. During periods of heavy rain or dust, you may need to replace them more often. Keeping your windshield clean can also help extend the life of your wiper blades.
