🔨 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 clearly see the cap and sealing area.

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 has a tether (a small strap that keeps it attached), let it hang freely.

Step 3: Inspect and clean the sealing surfaces

• Use a flashlight to inspect the rubber seal (gasket) on the old cap; cracks or flattening means it was leaking.
• Wipe the filler neck sealing surface with a clean shop towel to remove dirt.
• Tip: Dirt on the neck can mimic a “bad cap.”

Step 4: Install the new fuel cap

• Place the new cap onto the filler neck.
• Turn it clockwise until you feel it fully seat and it “clicks” several times.
• “Clicking” is the cap’s built-in clutch that prevents overtightening.

Step 5: Close up and verify fit

• Close the fuel door by hand.
• Use a flashlight to confirm the cap sits flat and the tether (if equipped) isn’t pinched.

✅ After Repair

• If you had a check-engine light from a loose/bad cap, it may take a few normal drive cycles to turn off on its own.
• If you have a scan tool, you can clear the code after confirming the cap is tight.
• After your next fill-up, tighten the cap until it clicks to prevent future EVAP leaks.
