📋 Before You Begin

• Park on level ground and shift to Park.
• Turn the engine off and remove the key/fob from the vehicle area.
• Wipe dirt around the filler area using a clean shop rag so debris doesn’t fall into the filler neck.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Use a flashlight to see the cap and tether clearly if lighting is poor.

Step 2: Remove the old fuel cap

• Put on nitrile gloves and safety glasses.
• Turn the cap counterclockwise until it releases.
• Let the cap hang by the tether (the strap that keeps the cap attached so it won’t get lost).

Step 3: Inspect and clean the sealing surfaces

• Use a flashlight to inspect the rubber seal on the old cap and the filler-neck sealing surface.
• Wipe the filler-neck lip and surrounding area with a clean shop rag.
• Tip: Dirt on the lip can cause EVAP leaks.

Step 4: Install the new fuel cap

• Align the new cap with the filler neck and turn it clockwise by hand.
• Keep turning until you feel/hear it click and it’s snug.
• Tip: Hand-tight only—no tools.

Step 5: Close the fuel door

• Close the fuel door fully and make sure it latches.

✅ After Repair

• Start the engine and confirm there’s no fuel smell around the filler area.
• If you had a check engine light for an EVAP small leak/loose cap, it may take a few normal drive cycles to clear on its own after the cap seals correctly.
• If the light stays on after several days of driving, the issue may be elsewhere in the EVAP system.
