🔧 Camry - Fuel Cap Replacement
Replacing the fuel cap is a quick job: you remove the old cap from the filler neck and install the new one so it seals correctly. A good seal helps prevent fuel vapor leaks and can prevent a check-engine light caused by an EVAP leak.

📋 Before You Begin
- Park on level ground and turn the car OFF.
- Make sure the fuel door area is clean; use a clean shop rag to wipe dust away.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the fuel door
- Use your hand to open the fuel door.
- Put on nitrile gloves and safety glasses.
Step 2: Remove the old fuel cap
- Turn the cap counterclockwise by hand until it comes off.
- If it’s dusty, use a clean shop rag to wipe around the filler opening (don’t push dirt into the hole).
Step 3: Transfer the tether (if needed)
- If your cap is attached to a small strap (tether), move it to the new cap.
- If a clip is tight, use a plastic trim tool to gently pop it free. (A trim tool is a plastic pry tool that helps avoid scratching.)
Step 4: Install the new fuel cap
- Place the new cap on the filler neck and turn it clockwise by hand.
- Tighten until it clicks several times and feels secure.
- Clicks = proper seal.
Step 5: Close the fuel door
- Close the fuel door firmly with your hand.
✅ After Repair
- Start the car and confirm there’s no fuel smell around the fuel door area.
- If you had a check-engine light for a loose cap, it may take a few normal drive cycles to turn off after the seal is fixed.
