🔧 Accent - Fuel Cap Replacement

Replacing the fuel cap is a quick job: you remove the old cap and install a new one that seals correctly. A good seal helps prevent fuel vapor leaks and can prevent an EVAP-related check engine light.

Difficulty Level: Beginner | Estimated Time: 0.1-0.2 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Open the fuel door on the rear quarter panel.

Step 2: Remove the old fuel cap

• Use nitrile gloves and turn the cap counterclockwise until it releases.
• Let the cap hang by its tether (the small retaining strap/cord that keeps it from getting lost).

Step 3: Inspect and clean the sealing area

• Use a clean shop towel to wipe the filler neck sealing surface (the smooth rim where the cap seals).
• Tip: Dirt here can cause EVAP leaks.

Step 4: Transfer the tether (if needed)

• If your new cap does not include a tether, move the tether from the old cap to the new cap by unhooking it and snapping it into the same spot.
• If the tether does not transfer on your cap design, install the new cap without it.

Step 5: Install the new fuel cap

• Thread the new cap on by hand clockwise until it’s snug.
• Keep turning until you hear/feel it click (usually 1–3 clicks). This means it’s sealed correctly.

Step 6: Close the fuel door

• Close the fuel door firmly.

✅ After Repair

• Start the engine and make sure there’s no fuel smell around the filler area.
• If you had a check engine light due to a loose/bad cap, it may take a few drive cycles to turn off on its own.
• If the light stays on, the issue may be elsewhere in the EVAP system (not just the cap).
