Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather tools such as pliers, a lubricant spray, and a soft cloth.
Wear safety gloves to protect your hands.

2. Apply Lubricant

Spray a small amount of lubricant (such as WD-40) around the base of the fuel cap.
Allow the lubricant to penetrate for 5-10 minutes.

3. Attempt to Remove the Fuel Cap

Use a pair of pliers, wrapped in a soft cloth to avoid scratching, to grip the fuel cap.
Gently twist the cap counterclockwise while pulling it outward. Apply steady pressure without forcing it.
If the cap moves slightly, continue twisting and pulling until it releases.

4. Inspect and Clean

Once removed, inspect the fuel cap for damage or wear.
Clean any debris from the cap and the fuel filler neck using a soft cloth.
Check the rubber seal for cracks or deterioration; replace if necessary.

5. Reinstall or Replace Fuel Cap

If the fuel cap is in good condition, reinstall it by aligning it with the threads and turning clockwise until it clicks.
If damaged, replace it with a new OEM or compatible fuel cap.
