📋 Before You Begin

• 🅿️ Park on level ground, turn the engine off, and remove the key.
• Let the area around the fuel door cool down if the car was just driven.
• Wipe any dirt around the fuel filler opening using a clean microfiber towel so debris doesn’t fall in.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• With the car unlocked, press the fuel door to pop it open (it’s a push-to-open style).
• Use a flashlight to check the area is clean and undamaged.

Step 2: Remove the old fuel cap

• Turn the cap counterclockwise by hand until it releases.
• If your cap is tethered (attached by a strap), let it hang; if not, set it on a clean spot.
• Wipe the sealing surface (the round lip the cap seals against) with a clean microfiber towel.

Step 3: Install the new fuel cap

• Place the new cap on the filler neck and turn it clockwise by hand.
• Keep turning until it fully tightens and you feel/hear it “click” (that click means the seal is set).
• Hand-tight only—don’t use tools.

Step 4: Close the fuel door

• Press the fuel door closed until it latches flush with the body.
• Use a flashlight to confirm the door sits even and closed.

✅ After Repair

• Start the engine and confirm there’s no fuel smell around the fuel door.
• If you were replacing 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 after a few days, you’ll want the codes scanned to confirm the issue is resolved.
