🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the old fuel cap

• Turn the fuel cap counterclockwise by hand until it releases.
• If it is stuck, use a clean shop towel for grip only. Do not use pliers.
• Inspect the cap seal and the filler neck for cracks or dirt.

Step 2: Install the new fuel cap

• Place the new cap on the filler neck and turn it clockwise by hand.
• Keep turning until you hear or feel several clicks.
• Make sure the cap is fully seated and the tether, if equipped, is not pinched.
• Tighten by hand only.

Step 3: Verify the installation

• Close the fuel door.
• Start the vehicle and confirm the fuel cap warning light is off, if it was on before.
• If the warning light stays on, drive normally for a few trips so the system can recheck itself.
