⚠️ Safety & Precautions

  • Work with the engine off and the car parked on level ground.
  • Do not smoke or work near open flames.
  • Keep dirt and water out of the fuel filler neck.
  • No battery disconnect is required.

🔧 Required Tools

  • Clean microfiber cloth
  • Flashlight
  • Gloves

  • Fuel cap - Qty: 1

📋 Before You Begin

  • Park on level ground and turn the ignition off.
  • Let the area around the fuel door cool down if the car was recently driven.
  • Keep the old cap in place until the replacement is ready so the filler neck stays clean.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

  • Press on the fuel door to open it.
  • Use a flashlight if the area is dark.

Step 2: Remove the old fuel cap

  • Turn the fuel cap counterclockwise by hand until it comes free.
  • If it is attached to a tether, let it hang safely to the side.
  • Do not force a stuck cap.

Step 3: Inspect the sealing surface

  • Use a clean microfiber cloth to wipe the fuel filler neck.
  • Check that the rubber seal area is clean and undamaged.
  • If you see dirt, wipe it out before installing the new cap.

Step 4: Install the new fuel cap

  • Thread the new fuel cap on by hand clockwise.
  • Keep turning until it clicks several times and feels fully seated.
  • Torque to hand-tight only.

Step 5: Close the fuel door

  • Close the fuel door gently.
  • Make sure the cap sits flush and the door closes normally.

✅ After Repair

  • Start the engine and check for any warning lights.
  • If the check engine light was on for an evap leak, it may take a drive cycle to clear.
  • Make sure the cap stays tight after your next fuel stop.
