🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Press the fuel door to open it.
• If the door is dirty, wipe the area with a clean microfiber towel.

Step 2: Remove the old fuel cap

• Turn the fuel cap counterclockwise by hand until it comes free.
• Lift it off the filler neck.

Step 3: Inspect the seal

• Check the filler neck for dirt, damage, or a torn seal.
• Clean, dry surfaces seal best.

Step 4: Install the new fuel cap

• Place the new fuel cap on the filler neck.
• Turn it clockwise by hand until it clicks several times and feels fully seated.
• No torque spec applies because this cap is hand-tightened.

Step 5: Close the fuel door

• Close the fuel door firmly.
• Make sure the cap is not pinched or sitting crooked.

✅ After Repair

• Start the vehicle and check that the fuel cap warning is gone if it was on.
