📋 Before You Begin

• Park on level ground, shut the engine off, and remove the key.
• Let the area cool if you were just driving; fuel vapors are stronger when hot.
• Open the fuel door and locate the cap and tether (the small strap that keeps it from getting lost).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Use your hand to open the fuel door on the driver side rear quarter panel.
• Use flashlight to check for dirt or damage around the filler area.

Step 2: Remove the old fuel cap

• Use your hand (with nitrile gloves) to turn the cap counterclockwise until it releases.
• Set the cap aside and keep it attached to the tether if equipped.
• Wipe the sealing surface clean first.

Step 3: Inspect and clean the filler neck seal surface

• Use a clean shop rag to wipe the rim (the smooth surface where the cap seal sits).
• Make sure there’s no sand, rust flakes, or torn rubber stuck to the rim.

Step 4: Install the new fuel cap

• Align the new cap on the filler neck and use your hand to turn it clockwise.
• Tighten until you hear/feel at least 3 clicks (this is the cap’s built-in clutch that prevents overtightening).
• If your cap uses a tether, transfer/attach it the same way as the old cap (use your hands only).

Step 5: Close the fuel door

• Use your hand to ensure the cap is seated and the tether isn’t pinched.
• Close the fuel door until it latches.

✅ After Repair

• Start the engine and confirm there is no fuel smell around the fuel door area.
• If you replaced the cap because of a check engine light, the light may take a few drive cycles to turn off on its own.
• If the light stays on, the cap may not be clicking tight, or there may be another EVAP leak.
