🔧 Palisade - Fuel Cap Replacement

Replacing the fuel cap on your Palisade is a quick job that helps prevent fuel vapor leaks and can stop a check-engine light caused by an EVAP leak (often from a loose or bad cap). You’ll remove the old cap, install the new one, and make sure it clicks tight.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Use your hand to press the fuel door (it’s a push-to-open style) and swing it open.
• Put on nitrile gloves and safety glasses.

Step 2: Remove the old fuel cap

• Turn the cap counterclockwise until it releases, then lift it off.
• If the cap is attached to a tether (a short retaining strap), let it hang—don’t pull or twist the tether hard.
• Tip: If it’s stuck, twist slowly and steadily.

Step 3: Install the new fuel cap

• Place the new cap onto the filler neck opening.
• Turn it clockwise until you hear/feel it “click” several times and it stops tightening. This clicking is the cap’s built-in clutch that prevents overtightening.
• Gently tug the cap to confirm it’s seated and not loose.

Step 4: Close the fuel door

• Close the fuel door by pressing it until it latches flush with the body.
• Wipe any fuel residue off the area with a clean rag if needed.

✅ After Repair

• Start your Palisade and confirm there’s no fuel smell around the fuel door.
• If you had a check-engine light from a loose/bad cap, it may take a few normal drive cycles to turn off on its own.
• If the light stays on after a few days, the EVAP leak may be elsewhere and will need a code scan.
