I have a 2012 F-150 and last night the Gas Cap decided to fall off when I closed it after fueling up. The temps right now are 11'F so I am thinking I should leave it alone till it warms up to at least 32. Was wondering, does it glue on, or does it clip on? I tried for a little bit to re attach it, but heard to much creaking from cold plastic parts.

thanks for any help.
