📋 Before You Begin

• 🧤 Put on nitrile gloves to avoid fuel smell on your hands.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Use your hand to press the fuel door open.
• Use a flashlight if lighting is poor.

Step 2: Remove the old fuel cap

• Use your gloved hand to turn the cap counterclockwise until it comes off.
• If there’s a cap tether (strap), let it hang so it doesn’t scratch paint.

Step 3: Inspect and wipe the sealing area

• Use a clean shop towel to wipe the filler neck sealing surface (the smooth rim where the cap seals).
• Check for dirt, sand, or cracks on the old cap’s rubber seal.
• Clean sealing surfaces prevent EVAP leaks.

Step 4: Install the new fuel cap

• Thread the new cap on by hand clockwise.
• Continue turning until the cap clicks (usually 1–3 clicks). Do not force past the clicks.

Step 5: Close the fuel door

• Use your hand to close the fuel door until it latches flush.

✅ After Repair

• 🚗 Start your Telluride and confirm there’s no fuel smell near the fuel door.
• 🛠️ If you had a check engine light for an EVAP “loose cap” issue, it may take a few drive cycles to clear on its own.
• 🔍 If the light stays on after a few days, you may need a scan for stored EVAP codes (there could be another leak).
