Car Maintenance Checklist

In 2015, issues with the vehicles themselves were the primary cause of an estimated 44,000 car crashes in the United States. Most car wrecks where the vehicle is at fault result from poor vehicle maintenance.

Performing routine car maintenance for your vehicle is necessary to ensure that all systems and components are functioning properly, minimizing the chances of unexpected malfunctions, roadside emergencies and expensive repair needs. Basic car maintenance can also prolong your vehicle’s service life and boost its resale value. Keeping your car in good condition can save you on expensive repairs and even save you money on your insurance by preventing issues on the road. The key to achieving these advantages for your automobile is knowing when and how to perform proper maintenance techniques.

Creating a car maintenance checklist is an excellent way to stay on top of your vehicle upkeep. When you keep to a diligent maintenance schedule, you’ll ensure that all parts and systems are safe and accounted for at all times.

Monthly Car Maintenance

You can perform several short-term vehicle maintenance checks once a month to ensure optimal performance, safety and consistency. Though these precautions may seem inconsequential, they make a significant difference in your car’s overall system health. Even the most minor vehicle faults can result in major problems down the line, so adhering to a monthly car maintenance checklist is an excellent way to prevent these issues from worsening.

1. Check Oil and Coolant Levels

It’s wise to check your oil levels once a month to ensure that your engine has the lubrication necessary for smooth operation. Your car’s coolant levels contribute to engine health similarly to oil. Regularly checking your oil and coolant levels can prevent contaminant build-up, engine wear, grinding, deposits, and corrosion.

Check Oil and Coolant Levels

2. Examine Tire Pressure

Sufficient tire pressure ensures that you have control of your vehicle, which is why it’s vital to make sure your tires are adequately inflated each month, before road trips or when pulling a heavier load. You can manually check your tire pressure using these steps:

  1. Locate the tire and loading information label: You can find information about your tire’s recommended inflation pressure on the driver’s side door edge or the driver’s side door jamb, called a B-pillar. If the driver’s door edge is too narrow or the vehicle doesn’t have a B-pillar, you may be able to find the sticker on the inward-facing surface of the driver’s side door.
  2. Make sure your tires are cold: Your tires should be cold before you check them, which means they haven’t been used in at least three hours. This condition ensures that you get the most accurate reading.
  3. Use a tire pressure gauge: Remove your tire’s air valve cap and insert your tire gauge. If the reading is below the recommended levels, use an air pump to fill the tire with air. If the number is too high, let some air out.

3. Test All Lights

Burnt-out or broken bulbs can create safety hazards on the road, reducing visibility and making it harder for other drivers to see you and where you’re turning. You can easily inspect your car’s bulbs each month by turning on each of your vehicle’s lights walking around your car to make sure they’re working. You should also check for cracks to prevent moisture-related damage. 

Be sure to test your:

  • Headlights
  • Taillights
  • High beams
  • Brake lights
  • Back up lights
  • Turn signal lights

4. Examine Your Windshield

Inspecting your windshield monthly is essential, especially during colder months when visibility is crucial. Take a look at your wiper blades and confirm that they’re free of cracks, splits, wear and damage. You should also check wiper fluid levels and top it off as needed.

Car Maintenance Every Three Months

Your three-month car maintenance schedule is a bit more involved than your monthly checklist. You should perform this regular car maintenance every three months or every 3,000 miles.

Be sure to conduct the following checks, tests and replacements:

  • Inspect your battery and cables: Your car battery and cables are essential components of vehicle operation. Without them, your car cannot function, resulting in engine stalling, slowing and even failure. Verify that your car battery is free of corrosion and your cables are securely fastened to the battery to ensure optimal function.
  • Get an oil change: Though it’s a good rule of thumb to change your car’s oil every 3,000 to 5,000 miles, this frequency varies depending on numerous factors, such as vehicle age, oil type and driving conditions. You can schedule an oil change at your local mechanic or change it yourself using the owner’s manual, taking into account oil viscosity, mileage and oil type.
  • Replace your oil filter: You should also replace your oil filter any time you replace your oil. Regularly switching out your oil filter keeps your car running smoother for longer. It also protects your engine from contaminants like dirt, dust and water that can enter your oil and damage or clog the engine.
  • Check the exhaust: You should inspect your car’s exhaust for leaks, strange noises or signs of damage to maintain reliable engine performance, improve fuel consumption and reduce emissions.
  • Monitor the transmission fluid: You can check your vehicle’s automatic transmission fluid by putting your car in park with the engine running and then pulling out the transmission dipstick under the hood. If your fluid levels are low, consult your owner’s manual for the proper fluid type before replenishing it.
  • Inspect hoses: Your vehicle’s hoses must withstand coolant in extreme pressures, temperatures and conditions. You can determine if you need to replace your hoses by checking them for leaks, cracks, holes or brittleness. 
  • Check the belts: Like your hoses, it’s important to check your car’s V-belts and serpentine belts to make sure they’re tight and undamaged. These components are responsible for powering your car’s alternator, air conditioning compressor and power steering pump.
  • Examine the engine air filter: When you maintain your engine air filter with routine car maintenance, you prevent harmful contaminants like dirt, pollen, dust and debris from entering your engine. A clean filter will appear white or off-white. Be sure to replace old or noticeably dirty filters.
  • Check the power steering fluid: Check your power steering fluid levels when your car is warmed up and top it off if it looks low. If you find yourself frequently refilling the fluid, try looking for system leaks.
Car Maintenance Every Six Months

Car Maintenance Every Six Months

It’s necessary to conduct some additional car maintenance every six months or 6,000 miles, though these tasks won’t be too extensive.

1. Rotate Your Tires

Rotating your tires after six months or so reduces irregular wear, maintains fuel efficiency and increases the tires’ life span. Though every car is different, a general rule is to rotate your tires every 5,000 to 8,000 miles or when uneven wear is visible. Uneven tire wear can create vibrations, which can damage your vehicle. 

Be sure to check your owner’s manual for information regarding your particular vehicle and tires.

2. Get a Car Wash

Your car is exposed to various elements throughout the year, from mud to salt to sap to bird droppings. Though these contaminants are both normal and expected, they can damage your car’s paint and undercarriage over time if not properly removed. 

How much dirt and grime your car’s exterior accumulates varies based on where you drive and park regularly. However, most individuals can benefit from washing their cars every six months. Once clean, you should also wax your car to protect the finish and prevent rusting.

Lubricate the Chassis

3. Lubricate the Chassis

You should lubricate your car’s chassis components as part of your car maintenance routine to minimize wear and secure joints against moisture-related damage. Be sure to apply heavy-duty lithium grease internally, including the car’s bushings, sway bars, suspension joints, and steering joints.

To access your car’s undercarriage, use a jack or lift to hoist your vehicle upward. Next, load your grease gun before climbing underneath the vehicle. It’s crucial to have adequate area lighting and your owner’s manual on hand. Once beneath your car, go through and fill each reservoir at the proper lubrication points. It’s okay to exceed the reservoirs’ fill points as overfilling won’t cause any harm.

4. Replace Your Wiper Blades

When your wiper blades don’t make complete contact with your car’s windshield, they can smear, squeak, streak or skip, resulting in poor driving visibility. It’s essential to replace your wiper blades if you notice these patterns, along with other signs of damage, such as metal corrosion, cracks, breakage, lack of flexibility and rounded squeegee edges. However, it’s wise to replace your wiper blades twice a year, even if they don’t exhibit any physical damage.

Yearly Car Maintenance

Your yearly car maintenance routine should take place annually or after every 12,000 miles. When you perform basic car maintenance every 12 months, your car will be better for it in the long run.

1. Replace Cabin Air Filter

You can find your vehicle’s cabin air filter somewhere beneath the dashboard — often behind the glove box. Not to be confused with the car’s engine air filter, the cabin filter keep your air conditioner clean and running efficiently, preventing outside allergens from entering the air vents. When your car’s air conditioner is pollutant-free, you’ll breathe cleaner air throughout your ride.

2. Check Your Brakes

According to a survey conducted by the National Highway Traffic Safety Administration, brake failure was the cause of 25% of pre-crash events attributed to vehicle failure. That’s why inspecting these components yearly is crucial for preventing accidents.

Turn off your radio and listen for any sounds that might seem problematic when slowing down on the road. You should also check all elements of your brake system, including the fluid, linings, pads and rotors. You can also slow brake pad wear by clearing the dust from your breaks.

3. Replace Coolant

Your car’s coolant, also known as antifreeze, prevents your engine from overheating while lubricating all its moving parts to prevent cylinder, head gasket, water pump and piston damage. Draining and refilling your coolant removes rust and dirt particles that can clog the system.

Make sure to consult your owner’s manual to determine what type of coolant is best suited for your car type.

4. Lubricate Hinges

It can be easy to forget that your car’s door hinges require the same attention as its other components. Over time, your doors may begin to squeak, resulting from wear and tear on the hinges. You can minimize these effects by applying lubricant.

It’s safe to use any oil-based grease on the metal parts of hinges, and spray greases like lithium lube are convenient for harder-to-reach places. Petroleum jelly also acts as a more powerful alternative to lighter sprays. When lubricating your latches, try using silicone-based spray lubes like WD-40, as plastics don’t typically react as well with oil-based products.

After spraying the hinges, be sure to wipe off any excess lubrication to prevent it from trapping grime and other contaminants.

Vehicle Maintenance to Do Immediately

Sometimes, waiting to check or replace your car’s components until they appear on your car maintenance schedule isn’t enough. Occasionally, you may see mechanical problems arise that require immediate assistance. 

1. Investigate the Cause of a Check Engine Light

Though seeing your check engine light flick on is no reason to panic, it’s something you shouldn’t ignore. This light is part of your vehicle’s onboard diagnostics system. When this system detects an issue within the car’s electronic controls that it can’t correct, it’ll alert you using a yellow warning indicator. Most check engine light issues start out fairly minor and can worsen over time without the proper attention.

Car Maintenance Checklist

If your check engine light is on, try to:

  • Look for signs of a serious issue.
  • Tighten your gas cap.
  • Reduce your speed.
  • Cease any hauling.
  • Visit a mechanic.

2. Fix Fluid Leaks

Your car contains various fluids to promote safe operation. Any fluid leaks can impact your car’s performance and can even indicate severe engine damage. Common types of fluid leaks include:

  • Oil leaks
  • Coolant leaks
  • Brake fluid leaks
  • Power steering fluid leaks
  • Transmission fluid leaks

3. Diagnose and Resolve the Cause of Exhaust Smoke

It’s important to be wary of any exhaust smoke you notice from your vehicle. Exhaust smoke can appear in various colors, indicating different issues, including:

  • White smoke: White smoke signals that your coolant is seeping into the combustion chamber. It could also indicate a cracked engine block.
  • Black smoke: If you notice black smoke leaking from your exhaust, the engine may be burning too much fuel at once, causing significant damage to emissions-related components like oxygen sensors or catalytic converters.
  • Blue smoke: Blue smoke indicates that your engine oil is burning within the cylinder, which could cause engine failure or other ongoing issues. 

4. Change Burnt-Out Bulbs

Light bulb outages leave drivers without the safety and visibility necessary to drive. Besides creating safety risks, burnt-out bulbs can also get drivers in trouble with the law, earning them a fine. You should immediately get your car checked if you notice your lights dimming, flickering or burning out completely. 

Your bulbs can burn out for numerous reasons, including:

  • Car vibrations
  • Hand contact
  • Extreme temperatures
  • Water leaks in the housing

When to Replace Parts of Your Vehicle

There are some critical vehicle parts that you’ll eventually need to replace according to a basic car maintenance schedule, including:

  • Brake pads: A new brake pad measures around 1/2 inches thick, and when it reaches 1/8 inches, it is considered 75% worn. You should replace your brake pads when they hit this measure.
  • Battery: It’s a good rule of thumb to replace your car battery around its third year. Most batteries don’t last more than six years maximum.
  • Spark plugs: Your spark plugs’ service life depends primarily on how old your engine is, though you should generally replace them between 30,000 and 90,000 miles.
  • Timing belt: You should replace your timing belt around the 60,000-mile mark, though you should check your owner’s manual for more specific instructions.
