Your Nissan's Fuel Tank Cap is a car part that is often neglected. You remove the Fuel Tank Cap, top of your fuel levels, and then tighten it back into place with every trip to the pump, but you likely don't give this part another thought.
The Fuel Tank Cap serves an important purpose in the performance of your Nissan as a whole. For starters, it seals off your fuel tank and keeps outside dirt, water, and other harmful debris from getting into your fuel. But, it has another purpose, too. The Fuel Tank Cap is an integral part of the EVAP, or evaporative emissions system, within your Nissan.
When your engine is running, the fuel in your vehicle heats up and emits dangerous byproducts. However, with a properly working Fuel Tank Cap, the EVAP system can safely contain these exhaust gases to stop them from leaking out into the air around your vehicle.
If you aren't able to click your Fuel Tank Cap onto your fuel tank, or if it becomes loose after being tightened, you're likely dealing with an old or damaged cap. Since this component is also part of your EVAP system, your check engine light may come on if your gas cap is loose or broken. Other indicators of an old Fuel Tank Cap include strong gasoline odors while you drive and decreased fuel efficiency with no significant change in your travel behaviors.
There are several downsides to a Fuel Tank Cap that's no longer functioning correctly. A Fuel Tank Cap that doesn't fully seal may push harmful emissions into the atmosphere, and it could also create a domino effect of other issues in your Nissan. A broken Fuel Tank Cap can reduce your Nissan's engine performance lead to poor gas mileage, and cause fuel leaks. It's wise to replace your Fuel Tank Cap immediately once you notice that it is not operating as it should.
Replacing an old Fuel Tank Cap is simple, and you can do it at home. Just be sure to shop genuine Nissan parts online to enjoy a perfect fit for your model and trim.
