Taking care of your car doesn’t have to be an expensive affair. By performing a major service at home, which includes tasks like oil changes, replacing air and cabin filters, changing spark plugs, and swapping out the fuel filter, you can keep your car running smoothly and save yourself a significant amount of money. Not only will these tasks improve your car’s performance and efficiency, but they will also give you a great sense of accomplishment!
In this step-by-step guide, we’ll walk you through the process of performing a major car service, so you can get your hands a little dirty and take care of your ride at the same time.
What You’ll Need:
Before you get started, it’s important to make sure you have all the necessary tools and supplies. Here’s a checklist of everything you’ll need for this major service:
- New engine oil (refer to your car’s manual for the correct type and quantity)
- New oil filter
- New air filter
- New cabin filter
- New spark plugs
- New fuel filter (some newer vehicles have a lifetime fuel filter)
- Socket wrench and extension
- Oil filter wrench
- Drain pan (for used oil)
- Funnel
- Rubber gloves
- Rags or paper towels
- Car jack and jack stands (if needed for better clearance)
- Screwdrivers (for removing filters and components)
- Spark plug socket (special socket for spark plugs)
- Creeper or blanket (optional for comfort under the car)
With everything gathered and ready, let’s jump into the step-by-step process of performing a major service.
Step 1: Prepare Your Car
Ensure that your car is parked on a flat, level surface. If your car has been running, let it cool down for about 10-15 minutes to avoid burning yourself when handling hot components like the oil. Open the hood and locate the oil cap, loosening it slightly to allow air to flow as the oil drains. If your car has low clearance, use a car jack to lift it, and secure it with jack stands for better access underneath.
Step 2: Drain the Old Oil
Position your drain pan underneath the oil pan, which you’ll find under the engine (usually at the bottom of the car). Use a socket wrench to loosen the drain plug, and allow the oil to drain completely into the pan. Let the oil sit for several minutes to ensure you get all of the old oil out.
Once the oil has fully drained, replace the drain plug and tighten it with the socket wrench. Be careful not to overtighten it—just make sure it's snug to prevent leaks.
Step 3: Remove and Replace the Oil Filter
While the oil is draining, it’s time to tackle the oil filter. Using an oil filter wrench, carefully remove the old filter. Be prepared for some leftover oil to spill out, so keep your drain pan in place. Once the filter is removed, inspect the rubber O-ring on the filter to ensure it hasn’t stayed behind. If it has, remove it before putting the new filter in.
Before installing the new oil filter, dip your finger in the fresh oil and lubricate the rubber O-ring of the new filter. This ensures a good seal and prevents leaks. Now, screw the new oil filter into place by hand—don’t overtighten it, just make sure it’s snug.
Step 4: Add New Oil
Now that the oil filter has been replaced and the drain plug is secured, it’s time to add fresh oil. Using a funnel, slowly pour the new oil into the oil cap opening on the engine. Be sure to check the amount of oil your car needs in the owner’s manual. After pouring in the correct amount, replace the oil cap and wipe up any excess oil.
Start your engine and let it run for a minute or two. Afterward, turn it off, wait a few minutes for the oil to settle, and check the oil level using the dipstick. If needed, add more oil in small increments until the level is correct.
Step 5: Replace the Air Filter
The air filter is essential for keeping dirt and debris out of your engine, and over time it can get clogged, reducing engine efficiency. To replace the air filter, locate the air filter housing. It’s usually a rectangular box near the engine, secured by clips or screws.
Open the housing and remove the old filter. Take a moment to clean the inside of the housing if needed. Install the new air filter by ensuring it fits snugly in place. Close the housing and secure the clips or screws.
Step 6: Replace the Cabin Air Filter
The cabin air filter keeps the air inside your car clean by filtering out dust, pollen, and other allergens. A clogged cabin air filter can reduce airflow through the vents and make your car’s AC less effective. To replace it, locate the cabin air filter compartment. This is typically behind the glovebox or under the dashboard. You may need to remove screws or pull out the glovebox to access it.
Once you’ve located the old cabin air filter, remove it and replace it with a new one. Make sure it fits securely in place and that the airflow direction is correct (usually indicated by an arrow on the filter). Close the compartment, and you’re done with the cabin filter!
Step 7: Replace the Spark Plugs
Spark plugs are crucial for igniting the air-fuel mixture in your engine’s cylinders. Over time, they can wear out, affecting your engine’s performance. To replace the spark plugs, start by locating them—usually near the top of the engine. You may need to remove a few components to get to them, like coil packs or other engine covers.
Once you’ve accessed the spark plugs, use a spark plug socket to carefully remove each one. Take note of the condition of the old plugs; if they’re worn or covered in carbon buildup, it’s definitely time to replace them.
Before installing the new spark plugs, check the gap (the space between the electrodes) using a spark plug gap tool. Refer to your car’s manual for the correct gap setting. Once the gap is correct, install the new plugs and tighten them by hand. Use a torque wrench to tighten them to the manufacturer’s recommended torque specification.
Step 8: Replace the Fuel Filter
Replacing the fuel filter is another essential maintenance task. Over time, the filter can clog, restricting fuel flow to the engine and causing poor performance. The fuel filter is usually located along the fuel line, either in the engine bay or underneath the car near the fuel tank.
To replace the fuel filter, locate it, then relieve the fuel system pressure by disconnecting the fuel pump fuse and running the engine until it stalls. Once the pressure is released, disconnect the fuel lines from the old filter (be cautious of any remaining fuel that may spill). Remove the old filter and install the new one in the correct orientation.
Reconnect the fuel lines, replace the fuse, and check for any fuel leaks. If everything looks good, you’re done!
Step 9: Clean Up and Dispose of Old Oil and Filters
After completing the service, make sure to clean up any spilled oil and dispose of your used oil and filters properly. Take the old oil to a recycling center or an auto parts store that accepts used oil. It’s crucial to handle waste oil responsibly, as it can be harmful to the environment.
Step 10: Check Everything
Start your car again to ensure it runs smoothly. Check for any leaks around the oil filter and drain plug. Also, test the air conditioning and heating to ensure the cabin air filter is working properly. Finally, take a quick drive to make sure the engine is running smoothly and that there are no strange sounds or warning lights.
Congratulations! You’ve successfully completed a major car service, which included an oil change, air and cabin filter replacements, spark plug changes, and a fuel filter swap. By keeping up with these essential maintenance tasks, you’ll not only keep your car running at its best but also extend its lifespan.
Remember, performing these tasks regularly can save you money on mechanic fees while giving you a greater understanding of your vehicle. If you ever feel unsure about any step, don’t hesitate to consult your vehicle’s manual or ask for professional advice.Â
