🔧 Silverado 1500 - Fuel Cap Replacement

Your Silverado uses a capless fuel filler, so there normally isn't a threaded factory gas cap to replace. To add protection, fit the Motorad MGC916 locking fuel-filler cover directly over the capless opening.

Difficulty Level: Beginner | Estimated Time: 5-10 minutes

Assumption: You mean the removable cover at the fuel-filler opening, not the painted exterior fuel door.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Fuel Door

• Press and release the rear edge of the exterior fuel door, then swing it open.
• Use the safety glasses and nitrile gloves while working near the fuel opening.

Step 2: Inspect the Capless Filler

• Check the filler opening for sand, dirt, broken plastic, or damage.
• Use the clean microfiber cloth to wipe around the outside rim.
• Do not push dirt through either internal sealing flap.
• Clean the rim, not inside the neck.

Step 3: Prepare the Locking Cover

• Use the supplied key to place the locking cover in its unlocked position.
• Check that the locking tabs move when the key is turned.
• No torque specification applies because the cover installs by hand.

Step 4: Install the New Cover

• Center the cover squarely over the capless filler opening.
• Press it into place by hand and turn it in the locking direction until fully seated.
• Use the supplied key to lock it, then remove the key.
• Pull gently on the cover to confirm it cannot be removed.
• Never use pliers. This job needs fingers, not horsepower.

Step 5: Close the Fuel Door

• Make sure the cover doesn't contact the inside of the exterior fuel door.
• Swing the fuel door closed and press its rear edge until it latches.

✅ After Repair

• Unlock and remove the cover once to verify that the key works correctly.
• Reinstall and lock it again before driving.
• If a check-engine light was caused by a capless filler sealing problem, a cover may not fix it. Inspect the internal filler seals for dirt or damage.
• No programming, scan-tool reset, or battery procedure is required.
