🔧 Forte - Engine Air Filter Replacement

Replacing the engine air filter on your Forte keeps dirt out of the engine and helps maintain fuel economy and smooth acceleration. This is a quick job because the filter sits in an air box right in the engine bay.

Difficulty Level: Beginner | Estimated Time: 10-20 minutes


⚠️ Safety & Precautions

  • 🧤 Let the engine cool a few minutes before working near it.
  • 👓 Keep fingers clear of the radiator fan area in case it cycles on.
  • 🔌 Battery disconnect is not required for this repair.

🔧 Required Tools

You'll need the following tools for this repair:

  • Nitrile gloves
  • Safety glasses
  • Flathead screwdriver
  • Shop towel

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Engine air filter - Qty: 1

📋 Before You Begin

  • 🅿️ Park on level ground, shift to Park, and set the parking brake.
  • 🧼 Have a shop towel ready to wipe dust inside the air box.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the air filter box

  • Open the hood and find the black plastic air filter box connected to the large intake tube.

Step 2: Unclip or loosen the air box cover

  • Release the metal retaining clips around the air box lid by hand.
  • If your air box uses a clamp or screw, use a flathead screwdriver to loosen it.
  • Don’t remove the whole air box.

Step 3: Remove the old air filter

  • Lift the air box cover just enough to access the filter.
  • Pull the old filter straight out.
  • Use a shop towel to wipe loose dirt from the bottom of the air box.

Step 4: Install the new air filter

  • Place the new filter into the air box in the same orientation as the old one.
  • Make sure the filter’s rubber edge (gasket) sits flat all the way around. This prevents unfiltered air leaks.

Step 5: Close and secure the air box

  • Close the air box lid fully.
  • Re-latch the clips by hand, or tighten the clamp with a flathead screwdriver until snug (do not over-tighten plastic).

✅ After Repair

  • ✅ Start the engine and listen for any hissing/whistling that could indicate the air box isn’t sealed.
  • 🔍 Recheck that all clips/clamps are fully secured and the lid is seated evenly.
