The 2011 CR-V uses a cartridge-style oil filter mounted on top of the engine

The oil filter on a 2011 Honda CR-V is not the spin-on canister type you might expect. Instead, it's a cartridge filter housed in a plastic cap on top of the engine. This design is common across Honda models from that year. The filter sits directly above the engine block, making it relatively straightforward to access without removing other components.

You'll find the filter cap near the center-front of the engine, marked with a wrench symbol. The cap itself is white or black plastic, roughly three inches in diameter. When you remove it during an oil change, you'll see the cylindrical filter element inside. This cartridge design means you replace just the filter media, not an entire canister, which can save money over time.

The 2011 CR-V comes in two engine sizes — the 2.4-liter four-cylinder (standard) and a 3.5-liter V6 (available in some trims). Both use the same cartridge-style filter in the same location, so the replacement process is identical regardless of which engine your vehicle has.

Key Takeaways

  • The 2011 CR-V filter is a cartridge type housed in a plastic cap on top of the engine, not a traditional spin-on filter.
  • You will need a filter wrench (usually 74mm or 86mm, depending on engine size) to remove the cap, plus a new filter element and O-rings.
  • The replacement process takes 10 to 15 minutes and requires draining the old oil first, then removing the cap, replacing the filter and O-rings, and reinstalling the cap.
  • Both the 2.4-liter and 3.5-liter engines use the same filter location and replacement procedure.

What you need before you start

Gather these items before you begin: a filter wrench (74mm for the 2.4-liter engine, 86mm for the 3.5-liter), a new filter cartridge (Honda part number 15400-PLM-A01 for most 2011 CR-Vs, though verify your specific engine), new O-rings (usually included with the filter), fresh engine oil, an oil drain pan, and rags or paper towels.

The filter wrench is essential — you cannot remove the cap by hand. Most auto parts stores stock both sizes, and they cost between $10 and $20. If you're unsure which size you need, bring your vehicle's year and engine size to the store and they will hand you the correct one. You can also rent a wrench from some stores for a small deposit.

Have your oil drain pan positioned before you start. The cartridge filter itself doesn't hold much oil, but the cap will drip when you remove it. Lay out your rags nearby to catch spills and keep your workspace clean.

Removing the old filter step by step

Start by warming the engine for two to three minutes, then turn it off and let it cool for five minutes. Warm oil drains faster and more completely. Locate the oil drain plug on the underside of the engine (you'll need to get under the vehicle or use a ramp), place your drain pan underneath, and remove the plug by turning it counterclockwise by hand. Let the old oil drain completely — this usually takes five to ten minutes.

Once the oil has drained, wipe the drain plug clean with a rag and reinstall it. Tighten it by hand first, then use a wrench to snug it down — do not over-tighten, as this can strip the threads. The drain plug should be snug but not cranked down hard.

Now move to the top of the engine. Locate the white or black plastic filter cap near the center-front. Position your drain pan underneath it to catch any remaining oil. Fit your filter wrench onto the cap and turn it counterclockwise. The cap will come off in your hand. Inside, you'll see the cylindrical filter element and two rubber O-rings — one on the cap itself and one on the filter housing below.

Remove the old filter element and discard it. Carefully peel off both O-rings and clean the surfaces where they sat with a clean rag. Do not use a scraper or anything abrasive — you can damage the sealing surfaces.

Installing the new filter and O-rings

Take your new filter element and the new O-rings that came with it. explore a thin coat of fresh engine oil to both O-rings — this helps them seal properly and makes installation easier. Place one O-ring on the filter housing (the stationary part inside the cap opening) and the other on the cap itself, in the grooves where the old ones sat.

Insert the new filter element into the housing, pushing it down gently until it seats. The element should slide in smoothly without resistance. If it doesn't, check that the O-ring on the housing is seated correctly in its groove.

Screw the cap back onto the housing by hand first, turning it clockwise. Once it's hand-tight, use your filter wrench to tighten it further. Turn the wrench about three-quarters of a turn past hand-tight — you want it snug enough that it won't leak, but not so tight that you'll struggle to remove it next time. Over-tightening is the most common mistake here.

Refilling the engine with fresh oil

Locate the oil filler cap on top of the engine (it usually says "OIL" on it). Unscrew it and set it aside. Pour in the recommended amount of fresh oil for your 2011 CR-V. The 2.4-liter engine holds approximately 3.7 quarts with a filter change; the 3.5-liter holds approximately 4.5 quarts. Check your owner's manual for the exact amount, as this varies slightly by year and trim.

Pour slowly and pause halfway through to let the oil settle. Replace the filler cap when you're done. Start the engine and let it run for 30 seconds to circulate the new oil and filter. Turn it off and wait two minutes, then check the oil level using the dipstick. Add a small amount more if needed to reach the full mark.

Checking your work and disposing of old oil

After the engine has run, turn it off and wait five minutes for the oil to settle. Pull the dipstick, wipe it clean, reinsert it fully, then pull it again to check the level. The oil should be between the minimum and maximum marks. If it's low, add a quarter-quart at a time until it reaches the full mark.

Inspect the filter cap area for any drips or leaks. If you see oil seeping from under the cap, turn off the engine, let it cool, and tighten the cap slightly more with your wrench. A small amount of oil residue is normal, but active dripping means the O-rings aren't sealing properly.

Dispose of your old oil responsibly. Most auto parts stores accept used oil for free, even if you didn't purchase supplies from them. Pour the old oil from your drain pan into a clean container with a tight lid, then take it to the store. Never pour used oil down a drain or into the ground.

Common mistakes and how to avoid them

The most frequent error is over-tightening the filter cap. This can crack the plastic cap or damage the O-ring seals, causing leaks. Remember: snug, not cranked. If you've over-tightened and the cap cracks, you'll need to replace the entire cap assembly, which costs more than the filter itself.

Another common issue is forgetting to oil the new O-rings before installation. Dry O-rings don't seal as well and can slip out of their grooves. A light coat of fresh engine oil takes 10 seconds and prevents this problem entirely.

Some people also install the filter element upside down or not fully seated. The element should slide down smoothly into the housing. If you feel resistance, stop and check the orientation. The element should be cylindrical and sit flush against the bottom of the housing.

Frequently Asked Questions

Can I use any filter cartridge, or does it have to be Honda brand?

You can use aftermarket filters from reputable manufacturers like Fram, Mobil 1, or Bosch, but the part number must match your engine size. Honda part number 15400-PLM-A01 is the OEM filter for most 2011 CR-Vs with the 2.4-liter engine. Verify the part number against your vehicle's specific configuration before purchasing, as some trims may differ.

What size filter wrench do I need?

The 2.4-liter engine uses a 74mm wrench, and the 3.5-liter uses an 86mm wrench. If you're unsure which engine you have, check your owner's manual or ask an auto parts store associate to look it up using your vehicle identification number (VIN).

How often should I replace the filter?

Honda recommends replacing the oil filter every time you change the engine oil. For a 2011 CR-V, this is typically every 3,000 to 5,000 miles with conventional oil, or every 7,500 to 10,000 miles with synthetic oil. Check your owner's manual for the exact interval for your vehicle.

What if oil is still dripping from the cap after I've tightened it?

Turn off the engine and let it cool completely. Remove the cap again and inspect the O-rings — they may be twisted, pinched, or not fully seated in their grooves. Clean the sealing surfaces with a rag, reposition the O-rings, and reinstall the cap. If the problem persists, the O-rings may be damaged and need replacement.

Can I change the filter without draining the oil?

Technically yes, but it's not recommended. Some oil will spill when you remove the cap, and you'll lose the opportunity to drain out old, contaminated oil. It's better to do both at the same time, which is why oil changes and filter replacements are always done together.
