🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and secure the hood

• Wear the nitrile mechanic gloves and ANSI Z87.1 safety glasses.
• Pull the interior hood-release handle, release the secondary latch under the front edge, and raise the hood using gloved hands.
• Confirm that the hood supports remain fully extended before reaching into the engine compartment.

Step 2: Locate the air-cleaner housing

• Use the LED inspection flashlight to find the large black plastic air-cleaner housing at the front passenger side of the engine compartment.
• Follow the wide intake duct from the engine toward the housing if needed.
• The air-cleaner housing is the box that holds the rectangular filter.

Step 3: Loosen the housing-cover screws

• Use the Torx T25 screwdriver to loosen the captive screws around the air-cleaner cover.
• Captive screws remain attached to the cover after they are fully loosened.
• Turn each screw counterclockwise until it spins freely. Do not force or remove it from the cover.
• Keep steady downward pressure on the screwdriver.

Step 4: Lift the air-cleaner cover

• Use gloved hands to lift the cover only far enough to access the filter.
• Move the attached intake duct gently. Do not pull on the airflow-sensor wiring or disconnect its electrical connector.
• Support the cover with one hand instead of placing strain on the intake duct.

Step 5: Remove the old filter

• Use gloved hands to note the filter’s orientation, then lift it straight out of the lower housing.
• Use the LED inspection flashlight to check that nothing falls into the clean-air outlet leading toward the engine.
• Do not start the engine while the filter is removed.

Step 6: Clean and inspect the housing

• Use the portable vacuum with crevice attachment to remove loose leaves, dust, and insects from the bottom of the housing.
• Keep the vacuum nozzle away from the airflow sensor and clean-air outlet.
• Use the LED inspection flashlight to inspect the housing for cracks, water, or damaged sealing surfaces.
• Do not use compressed air because it can push debris into the intake.

Step 7: Install the new filter

• Use gloved hands to place the new filter into the lower housing in the same orientation as the old filter.
• Make sure the filter’s rubber sealing edge lies flat around the entire opening.
• Confirm that no corner is folded, raised, or trapped outside its groove.
• A flat seal is more important than pressure.

Step 8: Refit the housing cover

• Use gloved hands to lower the cover squarely over the new filter.
• Check that the cover sits flush and does not pinch the filter seal.
• Make sure no hose or wire is trapped between the upper and lower housing sections.

Step 9: Tighten the cover screws

• Use the Torx T25 screwdriver to start every captive screw by hand before fully tightening any one screw.
• Tighten the screws gradually in an alternating pattern so the cover seats evenly.
• GM does not publish a separate service torque for these air-cleaner cover screws. Tighten them evenly until lightly seated; do not overtighten the plastic housing.

Step 10: Complete a final inspection

• Use the LED inspection flashlight to confirm the cover is fully seated on every side.
• Use gloved hands to verify the intake duct and airflow-sensor connector remain secure.
• Remove the tools, lower the hood carefully, and press it closed using gloved hands.

✅ After Repair

• ✅ Start the engine and let it idle for about one minute.
• 👂 Listen for a whistle or loud air-sucking sound, which could indicate a loose cover or pinched filter seal.
• 🚨 Confirm that no check-engine warning appears.
• 🔍 If a warning appears immediately, switch off the engine and inspect the airflow-sensor connector and intake duct.
• 📅 No dashboard reset is required. Record the mileage and replacement date for maintenance tracking.
