🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Find the large black plastic air box with a big intake tube attached to it.
• The filter sits inside this box, usually held by metal clips and/or small screws.

Step 2: Open the air filter housing

• Release the metal retaining clips by hand (flip them open).
• If your air box uses screws instead of clips, use an 8mm socket with a 1/4" ratchet to loosen them.
• If a clamp or clip is stubborn, gently pry with a flathead screwdriver (medium).
• Don’t force it—plastic gets brittle with age.

Step 3: Lift the cover and remove the old filter

• Lift the top half of the air box enough to access the filter (you usually don’t need to remove the whole lid).
• Pull the old filter straight out.
• Take note of how it sits (the rubber seal edge should match the shape of the box).

Step 4: Clean the air box sealing surface

• Use a clean, dry rag (or your glove) to wipe dust and leaves out of the lower half of the air box.
• Do not let dirt fall into the intake tube opening.

Step 5: Install the new air filter

• Place the new filter into the lower air box exactly like the old one.
• Make sure the filter sits flat and the rubber seal is fully seated all the way around.

Step 6: Close and secure the housing

• Lower the air box lid back into position.
• Re-latch the metal clips by hand.
• If equipped with screws, tighten using an 8mm socket and 1/4" ratchet until snug (do not over-tighten; it’s plastic).

✅ After Repair

• Start your Sierra 1500 and let it idle for 20–30 seconds.
• Listen for any hissing/whistling that could indicate the air box isn’t fully closed.
• Take a quick look to confirm all clips/screws are secured and the intake tube is seated.
