🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Pull the hood-release handle near the driver’s footwell.
• Move to the front of your Malibu, release the secondary hood latch, and raise the hood.
• Use the installed hood support system to secure it fully.

Step 2: Locate the Air-Cleaner Housing

• Use the small inspection flashlight to locate the black plastic air-cleaner housing on the driver’s side of the engine compartment.
• Identify the large intake tube running from the housing toward the engine.
• The housing cover is the removable upper half of this box.

Step 3: Loosen the Housing-Cover Screws

• Use the Torx T25 screwdriver to loosen each captive cover screw around the air-cleaner housing.
• Captive screws remain attached to the cover after they are loosened.
• Loosen the screws evenly until the cover is free. Do not force or remove the intake tube.
• Keep downward pressure on the screwdriver to prevent stripping.

Step 4: Remove the Old Filter

• Wear nitrile work gloves and safety glasses.
• Carefully lift the housing cover only as far as needed.
• Note how the old filter is positioned, then lift it straight out by its rubber edge.
• Avoid dropping dirt into the clean-air opening beneath the cover.

Step 5: Inspect the Housing

• Use the small inspection flashlight to check the lower housing for leaves, insects, or loose debris.
• Remove loose debris carefully by hand while wearing nitrile work gloves.
• Do not push dirt into the outlet leading toward the turbocharger.
• Inspect the housing edge and confirm that no wiring or hoses have been disturbed.

Step 6: Install the New Filter

• Place the new engine air filter into the lower housing in the same orientation as the old filter.
• Press around the filter’s rubber sealing edge with your gloved fingers.
• Confirm the seal lies flat inside its channel with no folds or raised corners.
• A raised seal can allow unfiltered air inside.

Step 7: Refit the Housing Cover

• Lower the cover squarely over the new filter.
• Check that the cover is fully seated and the filter is not pinched.
• Start every captive screw by hand with the Torx T25 screwdriver.
• Tighten the screws gradually in an alternating pattern.
• Torque to 2.5 Nm (22 in-lbs). This is inch-pounds, not foot-pounds.
• If a torque screwdriver is unavailable, make the screws gently snug without forcing them; the plastic housing can crack.

Step 8: Perform a Final Inspection

• Use the small inspection flashlight to check that the housing seam is even on every side.
• Confirm all screws are secure and no tools remain in the engine compartment.
• Lower the hood and press it closed firmly.
