š Before You Begin
- Park your Sorento on level ground and shift to Park.
- Pop the hood and support it securely.
- Locate the air filter box (the black plastic box connected to the intake tube near the front/side of the engine bay).
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the air filter housing
- Use a flashlight to find the air box lid and its clips or screws.
- If your air box uses metal clips, release them by hand; if theyāre tight, gently pry with a flathead screwdriver.
- If your air box uses bolts, remove them with a 10mm socket and 1/4" drive ratchet.
- Donāt force the lid; check for hidden fasteners.
Step 2: Remove the old air filter
- Lift the air box lid just enough to access the filter (you usually donāt need to remove the lid completely).
- Pull the old filter straight up and out by hand.
- Use a shop towel to wipe out loose dust from the bottom of the air box.
- Do not drop dirt into the intake opening.
Step 3: Install the new air filter
- Place the new engine air filter into the lower half of the air box.
- Make sure the filterās rubber edge (gasket) sits flat all the way around; no corners should be folded.
- Align the filter the same way the old one came out (some have a specific top/bottom orientation).
Step 4: Close and secure the air filter housing
- Lower the air box lid into place.
- Re-latch the clips by hand, or reinstall the bolts using a 10mm socket and 1/4" drive ratchet.
- Snug the bolts (do not over-tighten plastic). Torque to 5 Nm (44 in-lbs) if you have a torque wrench.
Step 5: Quick final check
- Confirm the lid is fully seated and all clips/bolts are secured.
- Make sure no tools or towels are left in the engine bay.
ā After Repair
- Start the engine and let it idle for 30 seconds.
- Listen for any whistling or hissing (can mean the air box lid isnāt sealed).
- If you hear a leak, shut it off and re-check the filter seating and latches.
