🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Fuel Door

• Use your hand to open the fuel door on the left rear side of your HR-V.
• Make sure the area around the fuel filler opening is clean.
• Use a clean shop rag to wipe away dirt around the cap before removing it.
• Keep dirt out of the tank.

Step 2: Remove the Old Fuel Cap

• Wear nitrile gloves and safety glasses.
• Use your hand to turn the old fuel cap counterclockwise until it comes loose.
• If the cap has a tether, unclip the tether from the fuel door by hand.
• A tether is the small plastic strap that keeps the cap attached to the vehicle.

Step 3: Inspect the Fuel Filler Neck

• Use a clean shop rag to gently wipe the sealing surface where the cap tightens.
• Check for dirt, rust, or damage around the filler neck opening.
• Do not push the rag into the fuel filler neck.
• If fuel smell is strong, pause and let the area air out before continuing.

Step 4: Install the New Fuel Cap

• Attach the new cap tether to the fuel door by hand if the replacement cap includes one.
• Place the new fuel cap onto the filler neck.
• Use your hand to turn the cap clockwise until it clicks.
• Continue turning until you hear at least one clear click.
• No torque spec is used for this cap; tighten by hand only.
• Do not use pliers.

Step 5: Close the Fuel Door

• Use your hand to close the fuel door firmly.
• Make sure the fuel door sits flush with the body panel.

✅ After Repair

• Start your HR-V and confirm there is no strong fuel smell near the fuel door.
• If a check engine light was caused by a loose or bad fuel cap, it may take several drive cycles to turn off on its own.
• A drive cycle means normal driving where the vehicle warms up, runs, and shuts off again.
• If the light stays on after several days of normal driving, scan the vehicle for codes before replacing more parts.
