The oil filter on a 2011 Honda Accord is located on the underside of the engine, on the passenger side, inside a cartridge-style housing. It is accessed from below the vehicle and is not a traditional spin-on filter.
Location overview across engine options
In 2011, the Accord offered both a 2.4-liter four-cylinder engine and a 3.5-liter V6. For both configurations, Honda uses a cartridge-type oil filter housed in a small access chamber on the lower portion of the engine block, typically on the passenger side near the oil pan. Access usually requires removing the front splash shield or underbody panel to reach the housing cap.
Engine variations and access
The 2.4L four-cylinder filter is generally found on the lower passenger side of the engine block, toward the front of the car. The 3.5L V6 places the cartridge housing in a similar area, but the exact position can vary slightly depending on engine mounting and related components. In both cases, you’ll access the filter from beneath the vehicle.
What you’ll need to perform a replacement
Before you begin, assemble the parts and tools required for a cartridge-style oil filter change and review the steps to ensure you’re prepared.
- New cartridge oil filter element
- New O-ring for the filter cap
- Correct engine oil and an oil drain pan
- Basic hand tools and, if needed, a filter cap wrench or strap wrench
- Ramps or jack stands, flashlight, and rags for cleanliness
With the parts and tools ready, you can proceed to replace the filter, taking care to avoid spills and to follow proper safety procedures.
Steps to locate and replace the cartridge oil filter
Below is a practical sequence to locate and replace the oil filter on a 2011 Accord. Always refer to the owner's manual or service documentation for torque specifications and VIN-specific details.
- Park on a level surface, engage the parking brake, and raise the front of the car if needed. Remove the front splash shield to access the filter housing.
- Place a drain pan under the engine and loosen the oil filter housing cap to release any residual oil pressure.
- Remove the old cartridge filter from the housing and discard it. Clean the inside of the housing housing where the filter seats.
- Install the new cartridge filter with a fresh O-ring on the cap, lubricating the O-ring with a small amount of clean oil.
- Reinstall the housing cap and tighten to the manufacturer’s specification. Reinstall any shields you removed.
- Refill the engine with the correct amount and grade of oil, then start the engine to check for leaks. Recheck the oil level and top off if needed.
Dispose of the used oil and old filter according to local regulations and guidelines.
Tips and cautions
If you cannot locate the filter or if the filter housing is difficult to access, consult the Honda service manual for your exact VIN. Some trims may require slightly different access points or tool requirements. If you’re unsure, a professional service may be the safest option.
