🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the old fuel cap

• Use nitrile gloves to keep fuel smell off your hands.
• Turn the cap counterclockwise until it releases, then lift it off.
• If your cap has a tether (a small strap that keeps it attached), let it hang.

Step 2: Inspect the filler neck sealing surface

• Use a flashlight to look at the rim where the cap seals.
• Use a shop towel to wipe away dust/grit from the sealing surface.
• Clean seal surfaces prevent EVAP leak codes.

Step 3: Install the new fuel cap

• Place the new cap onto the filler neck.
• Turn clockwise until it clicks several times (typically 2–3 clicks).
• Confirm the cap feels snug and cannot be turned easily without clicking.

Step 4: Close up

• Close the fuel door firmly.
• Use a shop towel to wipe any fingerprints or light fuel residue.

✅ After Repair

• Start your Sportage and verify there’s no fuel smell near the fuel door.
• If you replaced the cap because of a check-engine light (EVAP leak), the light may take a few normal drive cycles to turn off on its own.
• If the light stays on, you may need a scan tool to clear the code and/or confirm there isn’t another EVAP leak.
