The 2005 Accord uses a cartridge-style filter mounted on top of the engine

The 2005 Honda Accord has an oil filter that sits vertically on the top of the engine, not underneath like many other cars. It looks like a cylindrical canister about 3 inches tall and screws directly into the engine block. This design means you can reach it without getting under the car, and you won't have oil dripping on your face or arms during the change.

The filter is located on the driver's side of the engine, toward the back. On a four-cylinder Accord, it's straightforward to spot once you open the hood. On the V6 model, it's in roughly the same spot but slightly more recessed. Both are accessible with basic hand tools and take about five minutes to swap out once you've warmed up the engine.

Key Takeaways

  • The 2005 Accord's oil filter is a cartridge type mounted vertically on top of the engine, not a spin-on filter underneath.
  • You will need a filter wrench (a socket-style tool that grips the cartridge) and a drain pan to catch old oil when you remove the filter cap.
  • The correct replacement filter for all 2005 Accord models is Honda part number 15400-PLM-A01 or equivalent aftermarket filters rated for that part number.
  • Warming the engine for two to three minutes before changing the filter makes the old oil flow out faster and more completely.

What filter size and part number you need

Honda's official part number for the 2005 Accord oil filter is 15400-PLM-A01. This number covers all 2005 Accords—four-cylinder and V6 engines both use the same filter. If you're buying from a parts store, give them this number and they will hand you the right cartridge.

Aftermarket filters from Fram, Mobil 1, Bosch, and other brands also fit this process. Look for filters labeled as compatible with 2005 Honda Accord or with the OEM part number 15400-PLM-A01. The filter itself costs between $8 and $20 depending on the brand and whether you choose a standard or synthetic-rated cartridge. Buying the Honda-branded version usually costs a few dollars more than a generic equivalent, but the fit and seal are may provide.

Tools and materials you'll need

You need a filter wrench to remove the cartridge. This is a socket-shaped tool that grips the top of the filter canister so you can turn it counterclockwise. Most auto parts stores sell them for $10 to $15, and they fit many Honda models, so it's a tool worth owning if you plan to do your own oil changes. A 74mm or 86mm socket wrench also works if you already have one in your toolbox.

Bring a drain pan to catch the old oil that spills when you unscrew the filter cap. A standard oil drain pan holds several quarts and costs $5 to $10. You'll also want a rag or paper towels to wipe your hands and clean up drips. Some people use a small brush to clean the filter seating surface on the engine before installing the new cartridge, though this is optional.

Step-by-step removal and installation

Start by running the engine for two to three minutes to warm the oil. Shut it off and wait five minutes so the oil cools enough to touch but stays thin enough to drain quickly. Open the hood and locate the filter canister on top of the engine.

Place your drain pan underneath the filter. Use the filter wrench to turn the cartridge cap counterclockwise. The cap will loosen and you can unscrew it by hand. Oil will pour out—this is normal. Once the oil stops dripping, lift out the old filter cartridge and set it aside. Wipe the seating surface on the engine with a clean rag to remove any debris or old rubber seal material.

Insert the new filter cartridge into the opening. Hand-tighten the cap clockwise until it seats firmly. Do not over-tighten—hand-tight is sufficient. The rubber seal on the new cartridge will compress as you tighten it, and over-tightening can damage the seal or make it hard to remove next time. Start the engine and let it run for 30 seconds, then check underneath the cap for leaks. If oil is dripping, tighten the cap a quarter turn more.

Oil capacity and what to top off with

Changing the filter alone does not require adding new oil—the filter cartridge holds very little oil, roughly 0.3 quarts. If you are doing a full oil and filter change, the 2005 Accord holds 3.7 quarts for the four-cylinder engine or 4.5 quarts for the V6. Check your owner's manual or the oil cap under the hood to confirm which viscosity your engine needs. Most 2005 Accords use 0W-20 or 5W-20 synthetic or conventional oil.

If you are only changing the filter, you do not need to add oil. straightforward reinstall the cap, run the engine briefly, and check the dipstick after a minute to confirm the level is still in the safe range. The oil level should not drop noticeably from a filter change alone.

Common mistakes to avoid

The most common error is over-tightening the filter cap. Hand-tight is the correct tension. Over-tightening makes the rubber seal compress too much and can cause leaks or make removal difficult next time. If you tighten it with a wrench, you've gone too far.

Another mistake is forgetting to wipe the seating surface before installing the new filter. Old rubber seal material left behind can prevent the new cartridge from sealing properly, leading to leaks. A quick wipe with a rag takes 10 seconds and prevents this problem.

Do not drain the old oil down the sink or into the ground. Most auto parts stores and service stations accept used oil for free, and many will take it even if you didn't buy anything from them. Some municipalities have hazardous waste collection days where you can drop off used oil at no cost.

When to change the filter on a 2005 Accord

Honda recommends changing the oil filter every time you change the engine oil. For a 2005 Accord, that interval is typically every 5,000 to 10,000 miles, depending on whether you use synthetic or conventional oil and your driving conditions. Check your owner's manual for the exact interval for your vehicle, as it may vary based on the engine type and maintenance schedule.

If you drive mostly in stop-and-go city traffic, towing, or dusty conditions, change the filter at the shorter interval. If you drive mostly highway miles at steady speeds, the longer interval is usually safe. Some owners change the filter every 3,000 miles as a conservative practice, though this is more frequent than Honda specifies.

Frequently Asked Questions

Can I change just the filter without changing the oil?

Yes. The filter cartridge holds only a small amount of oil, so you can swap it without draining the pan. However, Honda recommends changing the filter every time you change the oil, so if your oil is due for a change, do both at once. If your oil was just changed 1,000 miles ago, changing the filter alone is fine.

What happens if I over-tighten the filter cap?

Over-tightening compresses the rubber seal too much and can cause it to leak or fail prematurely. It also makes the cap very hard to remove next time. Hand-tight is the correct tension—if you can't turn it by hand, it's too tight. Loosen it slightly and try again.

Is the Honda filter worth buying instead of an aftermarket brand?

The Honda filter (part 15400-PLM-A01) costs a few dollars more but guarantees fit and seal quality. Aftermarket filters from major brands like Fram and Mobil 1 are also reliable and cost less. Either works well; the choice comes down to budget and brand preference.

Do I need to replace the rubber seal on the cap?

No. The rubber seal is part of the new filter cartridge and comes pre-installed. You straightforward screw the new cartridge in and the seal compresses against the engine. Do not try to reuse the old seal or transfer it to a new cartridge.
