🔧 QX60 - Fuel Cap Replacement
Replacing the fuel cap on your QX60 is a quick job: remove the old cap and install a new one that seals correctly. A good seal prevents fuel vapor leaks (and can prevent a check-engine light related to the EVAP system).
Difficulty Level: Beginner | Estimated Time: 5-10 minutes
⚠️ Safety & Precautions
- Work in a well-ventilated area; fuel vapors are flammable.
- Engine OFF and no smoking/open flames nearby.
- Avoid topping off the tank after the pump clicks off.
- Battery disconnect is not required.

📋 Before You Begin

- Open the fuel door.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Remove the old fuel cap
- Put on nitrile gloves and safety glasses.
- Turn the cap counterclockwise by hand until it comes off.
- If it’s tethered (a small strap that keeps it attached), let it hang or unhook it carefully by hand.
Step 2: Inspect and clean the sealing area
- Use a flashlight to look at the filler neck opening.
- Wipe the sealing surface with a clean shop towel.
- Don’t drop dirt into the filler neck.
Step 3: Install the new fuel cap
- Place the new cap onto the filler neck and turn it clockwise by hand.
- Tighten until you feel and hear it “click” (typically 1–3 clicks). Hand-tight only.
- If equipped, reattach the tether by hand so the cap won’t get lost.
Step 4: Close up
- Close the fuel door firmly.
- Use the shop towel to wipe any fingerprints or fuel smell from the area.
✅ After Repair
- Start the engine and confirm there’s no fuel smell around the fuel door.
- If you had a check-engine light for a loose cap, it may take a few drive cycles to turn off on its own.
- If the light stays on, the cap may be incorrect or the EVAP system may have another leak.
