How To Open Gas Tank and Cap on a Chevy Malibu?

To open gas tank and cap on a Chevy Malibu, locate the fuel door release lever on the driver’s side floorboard, pull it, and the fuel door will pop open. Finally, unscrew the gas cap and lift it off the tank.

1. Finding the Gas Cap Door

Knowing the location of the gas cap door is the first step in accessing the tank. Luckily, finding the gas cap door on your Chevy Malibu is straightforward. For most models, the gas cap door is located on the car’s driver’s side, typically behind the rear door.

Finding Car Gas Cap Door

To locate the gas cap door, start by looking at the side of the car marked with a gas pump symbol. This symbol is usually located on the side of the vehicle, near the back. Once you’ve identified the gas pump symbol, check the area immediately behind it for a small door or panel.

2. Opening the Door

As mentioned, the gas cap door is typically located on the driver’s side of the vehicle, behind the rear door. Once you’ve found the door, you must push on it to release the latch. It’s important to note that the gas cap door latch can vary slightly depending on the year and model of your Chevy Malibu.

In some models, you may need to push the door inwards, while in others, you may need to pull it outwards. If you’re having trouble releasing the latch, consult your owner’s manual or speak with a Chevy dealership representative for assistance. Once you’ve successfully released the latch, the gas cap door should open, thus giving you clear access to the gas cap.

3. Unscrewing the Cap

Before unscrewing the gas cap, ensure that the car’s engine is turned off and that you are in a well-ventilated area. This will help prevent fire or harm from inhaling gasoline fumes.


When unscrewing the gas cap, grip it firmly and turn it counterclockwise until it is loose enough to remove. It’s recommended to keep the gas cap in a clean and safe place to prevent it from getting lost or contaminated.

Unscrewing Gas Tank Cap

If the gas cap is difficult to remove, do not use excessive force, as it could break or damage the cap or the gas tank. Instead, gently wiggle it while turning it counterclockwise to help loosen it.

4. Refueling

Regular unleaded gasoline is widely available at gas stations and recommended for most Chevy Malibu models. On the other hand, E85 is a blend of ethanol and gasoline that contains up to 85% ethanol.
While both fuel types are suitable for the Chevy Malibu, it’s essential to use the fuel type recommended by the vehicle’s manufacturer. Using the wrong kind of fuel, such as diesel in a gasoline engine, can cause severe damage and thus result in costly repairs. It’s also important to note that E85 may not be compatible with all Chevy Malibu models, and using it in a vehicle not designed for E85 can result in engine damage.

Another crucial aspect when choosing the fuel type is fuel efficiency. Regular unleaded gasoline is typically less expensive and more widely available than E85. However, E85 may offer a higher octane rating, which can improve the vehicle’s performance and fuel efficiency, especially in some specific Chevy Malibu models.

When refueling your Chevy Malibu, insert the gas pump nozzle into the tank opening. The pump should automatically shut off when the tank is complete, but be sure not to overfill the tank, as this can cause fuel to spill out and create a fire hazard. It’s also a good idea to avoid topping off the tank, as this can lead to fuel being pushed into the vehicle’s evaporative emissions system, causing problems over time.

5. Replacing the Cap

When you replace the gas cap, turn it clockwise until it clicks, indicating securely fastened. A loose cap can prompt the “check engine” light to turn on, decreasing fuel efficiency. Additionally, a loose gas cap can result in fuel vapors escaping from the tank, harming the environment and contributing to air pollution. So, take a moment to ensure the gas cap is appropriately tightened after refueling to avoid these potential problems.

6. Closing the Door

After filling up your tank, replacing the gas cap and tightening it securely is crucial. This will prevent fuel leaks or vapor emissions, which can be dangerous and wasteful.

When screwing the cap back on, turning it clockwise until it clicks is essential. This will indicate that it is properly fastened and securely sealed. A loose cap can cause a “check engine” light to appear on your dashboard and can also result in reduced fuel efficiency.

In addition to securing the gas cap, closing the gas cap door is essential. Push the door until you hear a clicking sound, indicating it has latched securely. Not only does this protect the gas cap from damage, but it also prevents any debris or dust from entering the fuel tank. This can be especially vital to keep in mind if you frequently drive on dusty or gravelly roads.

Furthermore, a securely closed gas cap door not only keeps debris from entering the tank but also helps maintain your Chevy Malibu’s overall appearance. It gives your car a tidy look that can make a big difference in its appearance.

7. Understanding Gas Cap Warning Light

A loose gas cap might seem like a minor issue, but it can cause significant problems for your Chevy Malibu. A gas cap that is not secured tightly can cause fuel vapors to escape and cause a malfunction in the vehicle’s emissions system. This can result in the check engine light appearing on your dashboard, indicating a problem with the engine or emissions system.

If the “check engine” light switches on, it’s essential to address the issue promptly by checking the gas cap and ensuring it’s tightened securely. A loose gas cap can also trigger a warning light, indicating that the cap is faulty and needs replacing.

Failing to address a loose gas cap can lead to decreased fuel efficiency and reduced engine performance. Over time, this may result in costly repairs and maintenance issues. In some cases, a malfunctioning emissions system can also lead to environmental damage, affecting air quality and health problems.

8. Carrying out Gas Cap Replacement

Firstly, it’s crucial to purchase the correct type of gas cap explicitly designed for your vehicle’s make and model. This can be done by visiting a local auto parts store or shopping online at a reputable retailer.

Carrying out Gas Cap Replacement

Once you have your new gas cap, it’s important to park your vehicle in a safe and secure location with the engine turned off before beginning the replacement process. The gas cap door is typically on the vehicle’s driver’s side, marked with a gas pump symbol.

To open the gas cap door, push on it firmly to release the latch and swing the door open. Next, unscrew the old gas cap by turning it counterclockwise until it comes off. Keep a firm grip on the old gas cap to avoid dropping it into the tank.

Now, take your new gas cap and screw it on clockwise until it clicks into place. It’s vital to ensure the gas cap is tightened securely to prevent fuel vapors from escaping and causing issues with your vehicle’s emissions system.

Finally, close the gas cap door by pushing it closed until it latches securely. This will help prevent the door from opening unexpectedly while you’re driving.
