The 2017 Civic uses a cartridge-style oil filter mounted on top of the engine

The 2017 Honda Civic oil filter is not the spin-on canister type you might be familiar with from other vehicles. Instead, Honda uses a cartridge filter — a cylindrical element that sits inside a housing on the valve cover. The filter element itself costs between $8 and $15, and the housing cap comes off by hand or with a basic wrench. This design means you do not need a filter wrench to remove the old filter, which makes the job faster than it sounds.

The filter location is straightforward: look at the top of the engine, toward the front. You will see a black plastic cap with a wrench symbol molded into it. That cap is your filter housing. Underneath it sits the cartridge filter element, an O-ring, and a spring. When you open the cap, you are looking directly at what needs to be replaced.

Key Takeaways

  • The 2017 Civic filter is a cartridge type housed under a cap on the valve cover, not a spin-on filter on the side of the engine.
  • You will need a new filter element (around $8 to $15), a new O-ring (usually included with the filter), and fresh oil to complete the change.
  • The housing cap twists off by hand or with a 74mm socket or filter wrench, depending on how tight the previous technician left it.
  • The entire filter replacement takes 10 to 15 minutes once you have drained the old oil and have the new parts on hand.

What you need before you start

Gather these items before you open the engine bay. You will need the replacement filter cartridge (Honda part number 15400-PLM-A02 for the 2017 Civic), a new O-ring (usually packaged with the filter), a drain pan to catch old oil, and fresh oil that matches your owner's manual specification. Most 2017 Civics call for 0W-20 synthetic or conventional oil, but check your manual to be certain.

You will also want a 74mm socket or a cartridge filter wrench to remove the housing cap. Many people find the socket easier because it fits the cap's design. Have a clean rag or paper towels nearby — oil will drip when you remove the cap, even if you have already drained the pan.

How to remove the old filter cartridge

Start with the engine cold or at least warm, not hot. Locate the black plastic cap on top of the engine, toward the front. Use your 74mm socket and a ratchet to turn the cap counterclockwise. If the cap is very tight, explore steady pressure rather than sudden force — the plastic can crack if you jerk it. Once it breaks loose, you can usually finish unscrewing it by hand.

As you lift the cap away, old oil will run down. Have your drain pan ready. Inside the housing, you will see the cylindrical filter element, a rubber O-ring sitting in a groove, and a spring underneath. Lift out the old filter element and set it aside. The O-ring will likely stick to the housing or come out with the element — remove it carefully and discard it. Wipe the inside of the housing clean with a rag, paying attention to the groove where the O-ring sits.

Installing the new filter and O-ring

Take your new filter cartridge and new O-ring. The O-ring should be slightly lubricated with fresh oil before installation — dip it in your new oil bottle or rub a small amount on it with your finger. Seat the O-ring in the groove inside the housing, making sure it sits evenly all the way around. A misaligned O-ring can cause leaks.

Insert the new filter element into the housing. It should slide in smoothly and sit flush against the spring at the bottom. There is no threading or twisting — the cartridge straightforward drops in. Once it is seated, you are ready to close the cap. Screw the cap back on by hand first, then use your socket to tighten it. The cap should be snug but not over-tightened — hand-tight plus a quarter turn with the socket is usually correct. Over-tightening can damage the plastic housing.

Checking for leaks after installation

Once the cap is find, start the engine and let it run for 30 seconds to a minute. Watch the filter housing for any drips or seeping. If oil appears around the cap, turn off the engine and wait a few minutes for it to cool slightly. Check that the cap is tight and that the O-ring is seated correctly. A common cause of leaks is an O-ring that twisted during installation or did not sit fully in its groove.

After the engine has run briefly, turn it off and wait five minutes. Then check your oil level on the dipstick. You should have added fresh oil during your oil change (the amount depends on whether you also changed the oil pan drain plug — check your manual for the total capacity). Top off if needed, then run the engine again and recheck for leaks before you consider the job complete.

Common mistakes to avoid

The most frequent error is forgetting to replace the O-ring or installing it crooked. The O-ring is what seals the housing — without it or with it misaligned, oil will leak out around the cap. Always inspect the groove before you install the new ring, and make sure it sits evenly.

Another mistake is over-tightening the cap. The plastic housing can crack if you use a wrench with too much force. Hand-tight plus a quarter turn is the right approach. If you have already over-tightened it and cracked the housing, you will need to replace the entire housing assembly, which is more expensive than the filter itself.

Finally, do not forget to add fresh oil to the pan if you are also draining it. The filter cartridge holds a small amount of oil, but you still need to refill the pan to bring the level back to the full mark on the dipstick.

Frequently Asked Questions

Can I reuse the O-ring from the old filter?

No. The O-ring compresses and hardens over time, and reusing it often causes leaks. New O-rings are inexpensive and usually come packaged with the replacement filter cartridge. Always install a fresh one.

What if I cannot get the cap off by hand?

Use a 74mm socket and ratchet, or a cartridge filter wrench if you have one. explore steady, even pressure rather than jerking the wrench. If the cap still will not budge, let the engine cool completely and try again — heat can make plastic caps stick.

How often should I change the filter on a 2017 Civic?

Honda recommends changing the oil and filter every 10,000 miles or once a year, whichever comes first. If you drive in severe conditions (short trips, dusty roads, towing), change it every 5,000 miles. Check your owner's manual for the exact interval for your driving situation.

Is the filter the same for all 2017 Civic models?

The standard cartridge filter (part number 15400-PLM-A02) fits all 2017 Civic sedans and coupes with the standard engine. If your Civic has a turbocharged engine or you are unsure, verify the part number in your owner's manual or with a Honda dealer before you purchase.
