You might not believe this but a loose fuel cap can cause a lot of trouble. Your fuel cap is designed to create a vacuum seal and when it cannot do that, your car, truck, or SUV will get a little cranky. How your gas cap becomes loose is two-fold: You might not have screwed it on tight or it’s old and cannot seal tight anymore. If the problem is the latter, you’ll need to replace your fuel cap. United Auto Care shares the signs that the fuel cap is too loose so you can make sure to get a new one when you need it.
You Can’t Get it To Tighten
Perhaps you didn’t screw the gas cap on tight but it wasn’t your fault. You keep turning it until it clicks but it keeps releasing after the click. This means the gas cap is worn and cannot tighten properly anymore. If this is the case, you might not be able to tighten until it clicks or, as mentioned a second ago, it might click but then release. Replace your gas cap if cannot get it to tighten and seal.
You Smell Gas All the Time
If you smell gas at any time coming from your vehicle, pull over to a safe space, stop, turn the engine off, and call for a tow. You should never smell gas coming from your car, truck, or SUV, and if you keep driving, you could ignite the fuel and start a car fire. If the problem is your fuel cap, the gasoline you smell is the vapors coming from your gas tank. Gas vapors ignite, so have the cap replaced ASAP.
Your Check Engine Light Won’t Turn Off
If you’re driving along and everything seems fine yet your check engine light comes on and won’t turn off, your gas cap could be loose. Pull over to a safe space and check the cap. If it’s loose, tighten it to see if the check engine light turns off. If you know you tightened it tight the last time you filled up your car, truck, or SUV and it came loose, you need a new cap. Pick one up at the local auto parts store.
