🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air filter box

• Use a flashlight to find the metal retaining clips around the air filter box lid.
• Release the clips by hand; if a clip is stubborn, gently pry it with a flathead screwdriver (medium).
• If your Sierra 1500 has screws/bolts instead of clips on the lid, loosen/remove them with an 8mm socket and 1/4" drive ratchet.
• Tip: Don’t force the lid—recheck for hidden fasteners.

Step 2: Remove the old air filter

• Lift the air box lid enough to access the filter (you usually don’t need to remove the whole intake tube).
• Pull the old filter straight out by hand.
• Take note of how it sits in the box (the new one must sit the same way).

Step 3: Clean the air box sealing surface

• Use a clean shop towel to wipe out loose dust/leaves from the bottom half of the air box.
• Wipe the rim where the filter seals so the new filter can seal tightly.
• Do not let dirt fall down the intake tube opening.

Step 4: Install the new air filter

• Place the new filter into the air box, making sure it sits flat and fully seated in its groove.
• Check that the filter’s rubber edge (seal) is not folded or pinched.

Step 5: Close and secure the air filter box

• Lower the air box lid into place, making sure it lines up evenly all the way around.
• Re-latch the clips by hand, or tighten the fasteners with an 8mm socket and 1/4" drive ratchet (snug only; there is typically no published torque for the air box lid fasteners).
• Do a quick visual check that no wiring or hoses are trapped under the lid.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds.
• Listen for a hissing/whistling sound (can indicate the air box lid isn’t sealed).
• If you hear a leak, shut it off and re-seat the lid and filter.
