Fuel door issues can be frustrating, especially when you’re in a hurry to get back on the road. The fuel door on your 2021 Challenger is designed to protect the fuel tank from dirt and debris, but it can become damaged or malfunction over time. If you need to replace the fuel door on your Challenger, follow these simple steps.
To begin, you’ll need to gather a few tools. You’ll need a flathead screwdriver, a Phillips head screwdriver, and a new fuel door. Once you have your tools, you can start by removing the old fuel door. Use the flathead screwdriver to pry the fuel door open, and then use the Phillips head screwdriver to remove the screws that hold the fuel door in place. Once the screws are removed, you can pull the old fuel door off of the vehicle.
Now that the old fuel door is removed, you can install the new fuel door. First, apply a thin bead of silicone sealant around the perimeter of the new fuel door. This will help to create a seal and prevent water and dirt from getting into the fuel tank. Next, line up the new fuel door with the mounting holes on the vehicle, and then insert the screws. Tighten the screws until they are snug, but do not overtighten them. Finally, use the flathead screwdriver to snap the fuel door closed.
Identifying the Fuel Door’s Location
Establishing the Vehicle’s Side:
* Locate the steering wheel and determine if your Challenger is a left-hand or right-hand drive model.
* If the steering wheel is on the left, it’s a left-hand drive vehicle, and vice versa.
Identifying the Fuel Cap Symbol:
* Scan the instrument cluster (the panel in front of the steering wheel) for a small, triangular symbol resembling a gas pump nozzle.
* This symbol indicates the location of the fuel door, typically on the same side as the fuel tank.
Observing Exterior Markers:
* Exit the vehicle and inspect the exterior for a small arrow or indent near the rear fender, usually positioned horizontally or vertically.
* These markers often line up with the fuel door’s location and provide a visual guide.
