🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the Air-Cleaner Housing

• Stand at the front of your Ridgeline and locate the black plastic air-cleaner housing on the passenger side of the engine compartment.
• Follow the large black intake tube from the engine to the housing if you have trouble finding it.
• The housing cover is the upper section that encloses the filter.

Step 2: Loosen the Housing Fasteners

• Use an 8mm socket, 3-inch socket extension, and 1/4-inch drive ratchet to loosen the captive cover bolts.
• Captive bolts remain attached to the cover after they are fully loosened.
• Loosen each bolt evenly. Do not force a bolt if it becomes angled or difficult to turn.

Step 3: Lift the Housing Cover

• Wearing nitrile work gloves and safety glasses, carefully lift the cover enough to access the filter.
• Do not sharply bend or pull the intake tube, wiring, or attached hoses.
• Support the cover while removing the filter so dirt cannot fall into the clean-air opening.

Step 4: Remove the Old Filter

• Lift the old engine air filter straight out by its rubber sealing edge using your gloved hands.
• Observe how the filter sits in the lower housing before removing it completely.
• Do not shake or tap the dirty filter over the open housing.

Step 5: Clean and Inspect the Housing

• Use a soft-bristle detailing brush to move loose leaves and debris away from the housing opening.
• Do not push dirt into the intake outlet leading toward the engine.
• Inspect the housing for cracks, standing water, or signs that rodents have entered it.
• Never blow debris toward the engine opening.

Step 6: Install the New Filter

• Place the new engine air filter into the lower housing in the same orientation as the old filter.
• Make sure the rubber sealing edge sits flat inside its entire channel.
• Run a gloved finger around the perimeter to confirm that no corner is folded or raised.
• Do not apply oil or grease to a standard dry replacement filter.

Step 7: Refit the Housing Cover

• Lower the cover carefully while checking that the filter remains seated.
• Verify that the cover is aligned with the lower housing and that no wiring or hoses are trapped between the halves.
• Start every captive bolt by hand with the 8mm socket and 3-inch socket extension before using the ratchet.

Step 8: Tighten the Housing Fasteners

• Use the 8mm socket and inch-pound torque wrench to tighten the cover bolts evenly in a crossing pattern.
• Torque to 3.9 Nm (35 lb-in).
• Stop once the specified torque is reached. The plastic housing can crack if overtightened.
• Snug plastic fasteners gently and evenly.

✅ After Repair

• Check that the housing cover is fully closed around its entire edge.
• Confirm that the intake tube and nearby electrical connectors were not disturbed.
• Remove all tools from the engine compartment and close the hood securely.
• Start the engine and let it idle for about one minute. Listen for an unusual rushing or whistling sound that could indicate a poorly seated cover.
• No electronic reset, scan-tool procedure, or filter programming is required.
