Review on 🔒 ACDelco GM Fuel Tank Filler Cap - Genuine Original Equipment, Part #20882859 by Ryan Lindstrom

This is my second. Same size fits my 2006 Saturn and my 2008 Saturn. I've received the dreaded P0442 diagnostic code multiple times and noticed that my gas cap was loose. After I put it on, it stays nice and tight. My wife has the same code on HER car, but since the nice guy at the oil change shop "fixed" it for her, she doesn't think she needs a new cap. . I bought one for the next time that happens.
