🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Open the fuel door by hand.
• Use a flashlight to look for dirt or damage around the filler opening.

Step 2: Remove the old fuel cap

• Grip the cap and turn it counterclockwise until it comes off.
• If your cap has a tether (a small strap that keeps it attached), let it hang safely.

Step 3: Clean the sealing area

• Use a clean shop towel to wipe the filler neck rim where the cap seals.
• Don’t push dirt into the filler neck.

Step 4: Install the new fuel cap

• Place the new cap on and turn it clockwise by hand.
• Tighten until you feel and/or hear it click (usually 1–3 clicks). This is what makes the seal.
• If there’s a tether, make sure it isn’t twisted or pinched.

Step 5: Close the fuel door

• Close the fuel door fully until it latches.

✅ After Repair

• Start the engine and confirm there’s no fuel smell near the fuel door area.
• If you had a check-engine light from a loose/bad cap, it may take a few drive cycles to turn off on its own.
• If the light stays on after a few days of normal driving, the issue may be another EVAP leak (hose, purge valve, etc.).
