2005 Nissan Altima - Gas Cap

Nissan Altima Gas Cap

The fuel cap or gas cap on your Nissan Altima keeps the gasoline clean by sealing off the opening to the gas tank. This prevents grit, debris, and water from getting into the fuel, and prevents fuel vapor from being released to the outside air. You may need to replace the fuel cap on your Nissan if it is no longer tightening or sealing properly, if the Check Engine light is on, or if you can smell gas from the rear of your car. A missing, worn, cracked, or broken fuel cap can cause you to lose as much as 30 gallons of fuel each year. Debris in the fuel can clog your Altima's fuel filter or damage the fuel pump, so replacing your gas cap when you notice a problem might save you the hassle of additional repairs. Gas caps are easily replaced, and O'Reilly Auto Parts carries gas caps, including locking fuel caps, for your Nissan Altima.
