Where is the oil filter located on a Honda Ridgeline?

The oil filter on a Honda Ridgeline is located on the engine block on the passenger side, typically accessible from beneath the vehicle with the undercarriage shield removed.

Because Ridgeline models have evolved across generations, the exact position and how you access it varies by year. The guide below covers the two main generations in production since 2006, plus practical tips for locating and servicing the filter safely.

Oil filter location by generation

Note that for each generation, the oil filter sits on the engine block and is generally found on the passenger side near the firewall. Access may require removing a splash shield or underbody cover.

• First generation (2006–2014): The oil filter is mounted on the passenger side of the engine block, roughly near the firewall, typically behind the right front wheel well and under a protective shield. Access usually requires dropping the lower engine shield or crossmember cover to reach the filter housing.


• Second generation (2017–present): The oil filter remains on the passenger side of the engine, a bit toward the front of the engine bay, and is often reached from underneath after removing the underbody panel or shield. Some trims use a cartridge-style filter inside a small housing with a removable cap for replacement.

In short, look on the passenger side of the engine block; if you can't see it, consult the owner's manual or a service manual for your exact year and trim to identify the filter housing location.

What you’ll need to replace the oil filter

Before you begin, gather the tools and supplies that make the job safer and cleaner.

• Basic hand tools (wrench/socket set, screwdrivers), an oil filter wrench if needed, a drain pan, gloves and rags.


• New oil filter that fits your Ridgeline’s 3.5L V6 and the appropriate engine oil type and amount for your model year.


• Optional: replacement O-ring or gasket for the filter housing cap, and a funnel for refilling oil.

Having the right tools on hand helps minimize time under the vehicle and reduces the risk of spills or damage to the filter housing.

Steps to locate and replace the oil filter

Follow these practical steps to safely locate and replace the Ridgeline’s oil filter.

1. Ensure the engine is cool, then park on a level surface and engage the parking brake. Lift the vehicle if needed and support with jack stands.


2. Place a drain pan under the engine to catch used oil, and remove the oil fill cap to vent pressure.


3. If equipped, remove the underbody shield or splash guard to access the area on the passenger side of the engine.


4. Locate the oil filter housing on the passenger side of the engine block. Depending on model year, you may see a spin-on canister or a cartridge-style assembly in a small housing.


5. For a spin-on filter: place the filter wrench on the filter canister and turn counterclockwise to remove. Let oil drain into the pan.


6. For a cartridge filter: remove the housing cap (with the appropriate tool) and pull out the old cartridge. Clean the housing and install a new cartridge or replace with a new filter according to the service manual.


7. Replace the seals or O-rings if required, lightly oil the new O-ring, and reassemble the housing or spin-on filter. Torque to the manufacturer’s specification if provided.


8. Rinse the drain pan area if needed, reinstall the underbody shield, and pour the recommended amount of fresh engine oil into the engine through the fill opening. Replace the cap.


9. Start the engine and check for leaks around the filter housing. Recheck the oil level with the dipstick and add more oil if necessary.

Careful inspection during and after the change helps ensure there are no leaks and the engine oil level remains within the recommended range.

Summary

For a Honda Ridgeline, the oil filter is typically located on the passenger side of the engine block, near the firewall, and accessed from underneath after removing the undercarriage shield. Exact placement varies by generation, with the 2006–2014 model year tending to have easier access behind the right front wheel well, and the 2017–present models occupying a similar area but sometimes requiring a different housing configuration. Always consult your year-specific manual if in doubt, and follow standard safety procedures when performing an oil change.
