The oil filter on a 2011 Honda Odyssey is inside a round black plastic canister mounted to the engine’s passenger side front. Access is usually from underneath the vehicle after removing the front undertray or wheel well liner.
Understanding the location on the engine
For the 2011 Odyssey with the 3.5-liter V6 (J35A), the oil filter is not a traditional spin-on canister. Instead, it lives inside a cartridge housed in a round plastic housing attached to the engine block. The housing sits toward the front of the engine on the passenger side, and many owners reach it from below by removing protective coverings.
What you’ll see when you locate it
The housing resembles a circular cap with a removable top. Inside is the cartridge filter element; the cap also seals the housing with an O-ring. The exact appearance can vary slightly depending on trim and service coverage, but the basic layout remains the same across 2011 Odyssey models.
What you need before you start
Gather tools and parts before you begin to safely remove the filter and install a new cartridge.
- New oil filter cartridge compatible with the 3.5L V6
- New O-ring or gasket for the housing cap
- Appropriate engine oil as specified in the owner's manual
- Oil drain pan
- Ramps or jack stands and wheel chocks
- Socket wrench with the correct size for the filter housing cap (size varies by vehicle)
- Flat tools and clean rags for cleaning and inspection
Having the right tools and replacements on hand helps ensure a clean and safe oil-change process.
Step-by-step access and replacement
The following steps outline a typical procedure for replacing a cartridge-style oil filter on this vehicle. Always refer to the owner's manual for torque specs and any model-year quirks.
- Secure the vehicle: park on a level surface, engage parking brake, place wheel chocks, and raise the vehicle if needed to access the undercarriage.
- Expose the oil filter housing: remove the front undertray or the passenger-side wheel well liner to gain access to the oil filter canister.
- Prepare for drainage: position an oil drain pan beneath the oil pan to catch any oil that spills when the housing is opened.
- Loosen the housing cap: using the appropriate socket or tool, carefully loosen and remove the oil filter housing cap. Expect some oil to seep out as the cap comes free.
- Replace the filter: remove the old cartridge, inspect the housing for debris, install a new O-ring on the cap if provided, and insert the new cartridge into the housing. Reinstall and tighten the cap to the specified torque.
- Refill and verify: add the correct amount of engine oil, start the engine, check for leaks around the housing, and recheck the oil level after a short runtime.
After the procedure, dispose of old oil and the used filter properly, and confirm there are no leaks before resuming normal vehicle operation.
Additional considerations
If you’re unsure about any step, or if space is too tight to safely access the housing, consult a professional technician. Some owners may prefer to perform only the basic drain and fill if they’re not comfortable replacing the cartridge filter themselves.
Summary
In short, the 2011 Honda Odyssey’s oil filter is housed in a round black plastic cartridge housing on the engine’s passenger side front. Access generally requires removing a protective undertray or wheel-well liner to reach the housing from underneath. With the right tools and replacements, you can replace the cartridge-style filter by removing the cap, swapping in a new cartridge, reseating the cap, and refilling the engine with oil. Always follow the manual for torque specs and safety precautions, and dispose of used oil responsibly.
