📋 Before You Begin

• Park the Equinox on a flat surface, set the parking brake, and turn the engine off.
• Open the hood using the hood release inside the cabin, then release the hood latch at the front of the vehicle and secure the hood prop rod.
• Locate the engine air filter housing: it is the black plastic box with a large intake hose near the front/driver side of the engine bay.
• Make sure you have the new air filter handy before you open the housing so dust doesn’t blow into the air box.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Open the hood and secure it with the prop rod.
• Find the engine air box: a black rectangular plastic box on the driver side front of the engine bay with a large accordion-style hose going to the engine.
• Look for any clips or bolts on the top cover.

Step 2: Identify fasteners on the air box cover

• Most 2.4L Equinox models use a combination of metal clips and/or 10mm bolts on the air box cover.
• Check all sides of the cover so you don’t miss a clip or bolt.
• Remember where each fastener goes as you remove it.

Step 3: Release the clips and remove bolts

• If there are clips:
  • Use the flathead screwdriver to gently pry and release each clip holding the cover.
  • Flip the clips away from the cover so they don’t snap back.
• If there are bolts:
  • Use the 10mm socket, 6" extension, and 1/4" drive ratchet to loosen and remove each 10mm bolt securing the cover.
  • Place the bolts in a safe spot so they don’t fall into the engine bay.
  • Reinstallation torque (if specified): 3 Nm (27 in-lbs) — this is just snug, not very tight.

Step 4: Lift the air box cover

• Gently lift the air box cover upward. It may be hinged on one side, so open it like a book.
• If it feels stuck, check again for any hidden clip or bolt before forcing it.
• You do not need to disconnect the big air hose for this job; just tilt the cover enough to access the filter.
• Move slowly to avoid cracking the plastic.

Step 5: Remove the old air filter

• Note how the filter is sitting in the box: which side is up and which side faces the engine.
• Grab the filter by one end and pull it straight up and out of the housing.
• Be careful not to drop dirt into the bottom of the air box.
• You can take a quick photo to remember orientation.

Step 6: Clean the air box

• Use the small soft brush to gently loosen dust and debris in the bottom of the air box.
• Use the clean shop rag to wipe out loose dirt. Do not use water or cleaners inside the air box.
• Make sure nothing falls into the air intake opening leading to the engine.
• Clean box helps the new filter work better.

Step 7: Install the new air filter

• Compare the new filter to the old one. The size and shape should match.
• Place the new filter into the air box in the same orientation as the old one. The rubber sealing edge should sit flat all around the edges of the box.
• Press gently on the edges to make sure it is fully seated and not twisted or folded.
• No gaps should be visible around the rubber seal.

Step 8: Refit the air box cover

• Lower the air box cover back into place, making sure the cover edge fits into any grooves or tabs on the lower half of the box.
• Check that no part of the new filter is sticking out or pinched by the cover.
• If the cover does not sit flat, open it again and re-check filter seating.

Step 9: Secure clips and bolts

• If you have clips:
  • Snap each clip back into place by hand. You should feel or hear a click.
• If you have bolts:
  • Install each 10mm bolt by hand a few turns to avoid cross-threading.
  • Use the 10mm socket, 6" extension, and 1/4" drive ratchet to tighten the bolts until they are just snug.
  • Torque to 3 Nm (27 in-lbs) if you have a small torque wrench. Do not overtighten; the cover is plastic.
• Go around the cover once more to confirm all clips/bolts are secure.

Step 10: Final checks

• Look around the air box and intake hose to make sure nothing is loose or disconnected.
• Remove any tools or rags from the engine bay.
• Lower the hood carefully and make sure it latches fully.
