🔧 HR-V - Fuel Cap Replacement

Replacing the fuel cap is a quick job: you remove the old cap and install a new one that seals correctly. A good seal helps prevent fuel vapor leaks and can prevent a check engine light related to the EVAP system.

Difficulty Level: Beginner | Estimated Time: 0.1-0.2 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel filler door

• Press/release the fuel door the usual way, then open it fully.
• Use a flashlight to look for dirt around the filler neck opening.

Step 2: Remove the old fuel cap

• Put on nitrile gloves and safety glasses.
• Turn the cap counterclockwise until it comes free, then remove it by hand.
• If your cap has a tether (the little strap that keeps it attached), gently unhook it from the cap using your fingers.

Step 3: Inspect and clean the sealing area

• Use a clean shop towel to wipe the rubber sealing surface on the filler neck (the ring where the cap seals).
• Check the old cap’s seal for cracks or a flattened rubber ring.
• Tip: Dirt here can cause EVAP leak codes.

Step 4: Install the new fuel cap

• If equipped, attach the tether to the new cap by hand (no tools).
• Thread the new cap on clockwise by hand until it seats.
• Continue turning until you feel/hear at least one “click” (that click means the cap is tight enough to seal).

Step 5: Close up and verify

• Close the fuel filler door firmly.
• Use a flashlight to make sure the cap sits flat and looks straight (not cross-threaded).

✅ After Repair

• Start the engine and make sure the fuel door is fully closed.
• If you had a check engine light for a loose cap/EVAP leak, it may take several normal drive cycles to turn off on its own.
• If the light stays on after a few days, you’ll likely need a scan to confirm the exact code.
