🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air cleaner box

• Use a flashlight to find the large plastic air box and intake tube (this is the “air cleaner housing,” the box that holds the filter).
• On your Acadia, it’s in the engine bay on the intake side and connects to the engine with a large plastic/rubber tube.

Step 2: Unlatch or loosen the air box cover

• If your air box uses metal clips, open them by prying gently with a flathead screwdriver.
• If your air box uses screws/bolts, loosen them with a 7mm socket and 1/4" drive ratchet (or a Phillips screwdriver if yours has Phillips screws).
• Only loosen enough to lift the lid.

Step 3: Lift the air box cover

• Lift the cover straight up by hand. If it feels stuck, recheck for a missed clip/screw and use a flashlight to confirm.
• Do not yank on the intake tube; lift the cover just enough to remove the filter.

Step 4: Remove the old filter

• Pull the filter straight out by hand (wear work gloves if it’s dusty).
• Use a flashlight to inspect the lower half of the box for leaves/sand.

Step 5: Clean the air box sealing surface

• Wipe the rim where the filter seals using a clean cloth (no tools needed).
• If you see loose debris in the bottom, carefully lift it out by hand—avoid pushing dirt down the intake.

Step 6: Install the new filter correctly

• Place the new filter into the lower air box the same direction as the old one.
• Make sure it sits flat and fully seated all the way around (no gaps).
• A crooked filter can let dirt bypass.

Step 7: Reinstall and secure the air box cover

• Set the cover back in place, ensuring it mates evenly with the lower box.
• Close the clips by hand, or tighten the screws with a 7mm socket and 1/4" drive ratchet (or Phillips screwdriver if equipped).
• Tighten snug—do not over-tighten plastic fasteners.

Step 8: Final quick check

• Use a flashlight to confirm the cover is fully seated and all clips/screws are secure.
• Make sure no tools are left in the engine bay.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds. Listen for any hissing/whistling that could indicate the air box isn’t sealed.
• If you hear an air leak, shut the engine off and re-check that the filter is seated and the cover is clipped/tightened evenly.
