📋 Before You Begin
- 🅿️ Park your Forte on level ground, select Park, apply the parking brake, and switch off the engine.
- ⛽ Verify that the replacement cap is an emissions-compatible cap made specifically for your Forte.
- 🕐 If the vehicle was recently refueled, wait briefly for any spilled gasoline to evaporate.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the Fuel Door
- Wear the fuel-resistant nitrile gloves and ANSI Z87.1 safety glasses.
- Pull the fuel-door release lever located on the floor beside the driver’s seat.
- Open the released fuel door by hand.
Step 2: Remove the Old Fuel Cap
- Turn the old cap counterclockwise by hand until it comes off the filler neck.
- Let any brief pressure release finish before fully removing the cap.
- Inspect the filler-neck sealing surface for dirt, rust, or damage.
Step 3: Release the Cap Tether
- Locate the small tether anchor attached inside the fuel-door area.
- Use the small nylon trim-removal tool to gently release the tether anchor from its mounting hole.
- A trim-removal tool is a nonmetallic lever that releases plastic clips without scratching paint.
- Do not pull directly on the tether because it may break and leave the anchor behind.
Step 4: Install the New Tether
- Compare the new cap, sealing gasket, and tether with the removed cap.
- Press the new tether anchor into the original mounting hole by hand until it is fully seated.
- If needed, use the flat side of the small nylon trim-removal tool to press the anchor evenly.
- Confirm that the tether is not twisted or trapped by the fuel door.
Step 5: Install the New Fuel Cap
- Place the new cap squarely onto the filler neck by hand.
- Turn the cap clockwise until it clicks at least once. There is no numerical torque specification; the cap’s clicking mechanism controls tightening.
- Stop after a clear click.
- Close the fuel door and press it until it latches flush with the body.
✅ After Repair
- ✅ Make sure the fuel door opens, closes, and latches normally.
- 🔍 Check that the cap gasket sits evenly and the tether does not interfere with the cap.
- 🚗 If a loose-cap warning or check-engine light was already on, it may take several normal driving cycles to turn off after the leak test passes.
- ⚠️ If the light remains on, the evaporative-emissions system should be scanned for diagnostic trouble codes.
