📋 Before You Begin

• Park on level ground and shut the engine off.
• Make sure you’re in a well-ventilated area (outside is best).
• Wipe dirt away from the fuel door area using a shop towel so debris doesn’t fall into the filler neck.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Open the fuel door on the rear quarter panel.
• Use a flashlight to check for dirt or damage around the filler neck.

Step 2: Remove the old fuel cap

• Put on nitrile gloves.
• Turn the cap counterclockwise until it releases, then pull it off.
• If your cap is tethered (attached by a strap), let it hang without twisting the strap. Don’t yank the tether.

Step 3: Inspect and clean the sealing surface

• Use a shop towel to wipe the filler neck sealing surface (the smooth rim the cap seals against).
• Check that no dirt, rust, or cracks are present.

Step 4: Install the new fuel cap

• Align the new cap on the filler neck and turn it clockwise by hand.
• Tighten until it clicks several times (usually 1–3 clicks). This is the built-in torque limiter that ensures a proper seal.
• Confirm the tether (if equipped) is not twisted and the cap sits flat.

Step 5: Close the fuel door

• Close the fuel door fully until it latches.
• Use a shop towel to wipe any fingerprints or spilled fuel.

✅ After Repair

• Start the engine and confirm there’s no fuel smell around the fuel door.
• If you had a check engine light from a loose cap, it may take a few drive cycles to clear on its own after the seal is restored.
• Recheck cap tightness after your next fill-up (listen for clicks).
