🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the Air Filter Housing

• Use your hands to identify the large black plastic air filter housing on the driver-side of the engine bay.
• Follow the wide black intake tube from the engine toward the air box.
• The air filter is inside this box.
• Take a photo first.

Step 2: Loosen the Intake Tube Clamp

• Use a flat-blade screwdriver to loosen the metal clamp on the intake tube where it attaches to the air filter housing.
• A clamp is a metal band that tightens around the rubber tube to hold it in place.
• You only need to loosen it enough so the tube can move slightly.

Step 3: Remove the Air Box Cover Screws

• Use a T25 Torx screwdriver to loosen the screws holding the air filter housing cover.
• A Torx screwdriver has a star-shaped tip used on many GM fasteners.
• These screws usually stay captured in the cover, so they may not fully come out.
• Do not force them once they spin freely.

Step 4: Lift the Air Box Cover

• Use your hands to gently lift the air filter housing cover.
• Move the intake tube only as much as needed to create space.
• Do not yank on any wiring or sensors attached near the intake tube.
• Gentle movement prevents cracks.

Step 5: Remove the Old Engine Air Filter

• Use your hands to lift the old air filter straight out of the housing.
• Notice which side faces up and how the rubber edge sits in the box.
• If leaves or dirt are present, use a shop vacuum to clean the lower air box.
• Use a clean microfiber towel to wipe the sealing surface where the filter sits.
• Do not push dirt into the intake tube opening.

Step 6: Install the New Engine Air Filter

• Use your hands to place the new engine air filter into the air box.
• Make sure the rubber edge sits flat all the way around.
• The filter should not be bent, pinched, or sitting crooked.
• A flat seal keeps dirt out.

Step 7: Reinstall the Air Box Cover

• Use your hands to lower the air filter housing cover back into place.
• Make sure the cover tabs and edges are seated evenly before tightening screws.
• Use the T25 Torx screwdriver to snug the cover screws evenly.
• Torque to snug only, about 2-3 Nm (18-27 in-lbs)
• Do not overtighten because the housing is plastic.

Step 8: Tighten the Intake Tube Clamp

• Use the flat-blade screwdriver to tighten the intake tube clamp.
• Make sure the tube is fully seated on the air box before tightening.
• Torque to snug only, about 3-4 Nm (27-35 in-lbs)
• Do not crush or deform the rubber tube.

Step 9: Final Visual Check

• Use your hands and eyes to confirm the air box cover is fully closed.
• Check that no tools, towels, or debris are left in the engine bay.
• Confirm the intake tube clamp is tight and the tube is not loose.

✅ After Repair

• Start your Traverse and let it idle for 30-60 seconds.
• Listen for hissing or whistling sounds near the air box, which can mean the cover or intake tube is not seated correctly.
• If the engine runs rough or the check engine light comes on, shut it off and recheck the air box cover and intake tube clamp.
• No scan tool reset is required after replacing the engine air filter.
