How to Check a Fuel Cap
- 1). Open the fuel door on your vehicle. Some cars require you to push a button by the seat or in the glove box, while others allow you to open it manually.
- 2). Grab the fuel cap and turn it to the left to remove it from the tank.
- 3). Replace the fuel cap, making sure that the threads on the cap and tank line up correctly and the cap is not skewed to the left or right.
- 4). Tighten the cap until you hear several clicks, indicating that the cap is correctly secured.
- 5). Close the fuel door.
