• Do not over-tighten the new cap; it should click and seal, not be forced.
• If the fuel door or filler neck area is dirty, keep debris out of the tank opening.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the old fuel cap

• Use your hand to turn the fuel cap counterclockwise until it comes free.
• Lift the cap away from the filler neck.
• If the cap is attached by a tether, leave the tether connected.

Step 2: Inspect the filler neck

• Use a clean shop towel to wipe the sealing surface on the filler neck.
• Look for cracks, dirt, or damage around the opening.
• A clean seal helps prevent warning lights.

Step 3: Install the new fuel cap

• Align the new cap with the filler neck threads.
• Use your hand to turn it clockwise until you hear several clicks.
• Keep turning until it is fully seated and snug.

Step 4: Close the fuel door and verify the seal

• Close the fuel door firmly.
• Start the engine and make sure no fuel cap warning appears.
• If a warning was already present, it may take a few drive cycles to clear.
