How to Change Your Car's Oil Filter and Housing

What You'll Need Before You Start

Changing your oil filter and housing requires a few basic tools and supplies. Here's what to gather:

• A new oil filter (the right size for your car)
• An oil filter wrench or socket
• A drain pan or container to catch old oil
• Clean rags or paper towels
• Jack and jack stands (if you need to raise your car)
• New oil (if you're doing a full oil change)
• Safety glasses
• Work gloves to protect your hands
• A flashlight or headlamp to see into tight spaces

Check your car's owner's manual to find the exact filter type and location. Different vehicles have different filter sizes and placements, so knowing yours ahead of time saves frustration. Your manual will also tell you the correct type of oil to use if you're replacing the oil at the same time.

Preparing Your Vehicle

Before you begin, park on a level surface and let your engine cool for a few minutes. A warm engine makes the job easier, but a hot engine can burn you. Give it about 5 to 10 minutes after driving to cool down enough to touch safely.

If your filter sits low on the engine, you may need to raise the front of your car using a jack. Always use jack stands for safety—never work under a car supported only by a jack. Place the jack stands on solid parts of the frame, not on plastic trim or bumpers.

Put on your safety glasses before you start. Oil can splash, and you want to protect your eyes. Wearing work gloves also keeps your hands cleaner and protects your skin from sharp edges on the filter housing.

Locating and Removing the Old Filter

Find your oil filter housing, which is usually a cylindrical canister on the side or top of the engine. It looks like a small metal can about 3 to 4 inches tall. Place your drain pan underneath to catch any spilled oil. Position it so it's directly under the filter—old oil will drip out when you loosen it.

Use your oil filter wrench to turn the housing counterclockwise. The wrench grips the filter so you can apply steady pressure without your hand slipping. Once it's loose enough, finish unscrewing it by hand. Be careful—there may still be warm oil inside. Let any remaining oil drip into the pan before you set the old filter aside.

Don't rush this step. Taking time to let the oil drain completely prevents spills on your driveway or garage floor.

Cleaning the Housing and Installing the New Filter

Wipe the filter housing threads clean with a rag. Remove any dirt or old gasket material so the new filter seals properly. The gasket is a rubber ring that creates a watertight seal. If old pieces of the gasket stick to the housing, the new filter won't seal correctly, and oil can leak out.

Take your new oil filter and apply a thin layer of fresh oil around the rubber gasket—the ring at the top of the filter. This helps create a good seal between the filter and the housing. Use just enough to coat it lightly; you don't need to soak it.

Screw the new filter onto the housing by hand until the gasket touches the housing surface. You'll feel slight resistance when this happens. Then turn it an additional three-quarter turn. Don't over-tighten—hand-tight is correct. Over-tightening makes it harder to remove next time and can damage the gasket.

Checking Your Work

Start your engine and let it run for a few seconds. Check under the filter housing for leaks. If you see dripping, turn off the engine and tighten the filter slightly. Wait a minute and check again.

Once the engine has run, turn it off and wait a minute for the oil to settle. Check your oil level on the dipstick and add more oil if needed. This is especially important if you changed the oil at the same time as the filter.

Dispose of your old oil properly. Many auto parts stores and service stations take used oil for free. Never pour used oil down the drain or into the ground—it harms the environment.

Key Takeaways

• Gather all tools and supplies before you start, including a drain pan, filter wrench, and safety gear.
• Let your engine cool slightly before working on it to avoid burns.
• Use a drain pan to catch old oil and prevent spills.
• Clean the filter housing threads before installing a new filter.
• Apply a thin layer of fresh oil to the new filter's gasket for a proper seal.
• Hand-tighten the new filter—don't over-tighten it.
• Check for leaks after starting the engine.
• Dispose of old oil at an auto parts store or service station.

Frequently Asked Questions

How often should I change my oil filter?

Most car manufacturers suggest changing your oil filter every time you change your oil. This is typically every 3,000 to 10,000 miles, depending on your vehicle and the type of oil you use. Check your owner's manual for the exact interval for your car. Changing the filter regularly keeps your engine clean and running smoothly.

What happens if I over-tighten the oil filter?

Over-tightening the filter can damage the rubber gasket, which causes oil to leak. It also makes the filter very hard to remove the next time you need to change it. Hand-tight plus three-quarter turn is the correct amount. You want it snug enough that it won't leak, but not so tight that you need tools to remove it later.

Can I change the oil filter without changing the oil?

Yes, you can change just the filter without changing the oil. However, many people change both at the same time because the filter and oil work together to keep your engine clean. If you change only the filter, the old oil will still be in your engine. Your owner's manual will tell you whether you need to change both at the same time or if you can do them separately.

Why do I need to apply oil to the new filter's gasket?

The oil on the gasket helps it create a tight seal against the housing. Without it, the gasket can stick to the housing when you try to remove the filter next time, making it difficult to unscrew. A thin coat of fresh oil also keeps the rubber from drying out and cracking.

What should I do if the filter leaks after I install it?

If you see oil dripping after you start the engine, turn it off and let it cool for a minute. Check that the filter is tight enough by turning it slightly clockwise with your hand. If it's already hand-tight, the gasket may not be sealing properly. Remove the filter, clean the housing threads again, and install a new filter, making sure to apply oil to the gasket first.
