Check Gas Cap Indicators

Check Gas Cap

Here we show three versions of the Check Gas Cap Indicator symbols, one of the few things the average driver can do anything about. The first two image symbols, which are really a half a car with an unscrewed gas cap, can look like a water pitcher with a screw or bolt next to it. The version with the full car at least eliminates the optical illusion, although all the gas caps look like oversized screws.

• Before moving on, are you sure one of these is your symbol?? If yes, then continue on below.
• Otherwise return to our main Picture Symbols page or the Text Symbols page and scan again!

Why does this matter?

Because, if you ignore one of these lights, the Check Engine light will likely come on next. So, if you see this light, or the text image below, stop the vehicle in a safe place and make sure the gas cap is tightened properly (to at least one click).

Also, note that a loose gas cap is an air or vacuum leak. Other leaks in the fuel system may fool your car into thinking that its gas cap is loose. So, in older vehicles, check that the cap’s seal is good and replace the cap if the seal is cracked or otherwise damaged. It is certainly worth a look and very inexpensive to replace.

If that doesn’t do the trick, your dealer or authorized service center will be needed.
