🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air box

• Locate the air filter box in the engine bay.
• Release the air box cover clips by hand. On this truck, the cover is usually held by metal or plastic latches.
• Keep the lid level to avoid spilling debris.

Step 2: Remove the old filter

• Lift the cover enough to access the filter.
• Pull the old air filter straight out by hand.
• Check the air box for dirt, leaves, or debris and wipe it clean with a shop rag.

Step 3: Install the new filter

• Place the new filter into the air box in the same position as the old one.
• Make sure it sits flat all the way around the edge.
• Do not force it if it feels crooked.

Step 4: Close and secure the air box

• Lower the air box cover carefully.
• Snap all retaining clips back into place by hand.
• Check the cover seam all the way around to confirm it is fully seated.

✅ After Repair
