🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air box and clear access

• Use a flashlight to find the air box cover and the fasteners holding it down (usually metal clips and/or screws).
• If anything lightly blocks access (like a small wire loom), gently move it aside by hand. Do not pull hard on wiring.

Step 2: Release the air box cover

• Unclip the air box cover by hand if it has metal clips.
• If your air box uses screws, loosen them using a small flathead screwdriver.
• Tip: Don’t force it—recheck for missed clips.

Step 3: Open the air box and remove the old filter

• Lift the air box cover straight up (or hinge it upward, depending on your Malibu’s housing).
• Pull the old filter straight out.
• Use a shop towel to wipe out loose dirt inside the lower half of the air box.
• Tip: Don’t let dirt fall into the intake tube.

Step 4: Install the new filter (orientation matters)

• Compare the new filter to the old one to confirm the same shape and size.
• Set the new filter into the lower air box exactly the same way the old one sat.
• Make sure the filter’s rubber edge sits flat all the way around (no corners folded).

Step 5: Close and secure the air box

• Lower the air box cover back into place.
• Reattach all clips by hand, or snug the screws with the small flathead screwdriver.
• Do a quick visual check that the cover is fully seated (an air leak here can cause a check engine light).

✅ After Repair

• Start the engine and let it idle for 15–30 seconds.
• Listen for any hissing/whistling near the air box (this can mean the cover isn’t sealed).
• If a check engine light comes on, re-check that the air box cover is fully clipped/screwed down and the intake tube connection wasn’t disturbed.
