Question about 2012 Chevrolet Impala LS Sedan 3.6L V6 FFV 6-speed Automatic
Gas cap ever tightens but no check engine light on, yet. I'm trying to prevent having an issue. Should I replace the gas cap?
Some gas caps have a built in slip preventing over tightening, so no engine light, no worry. The cap will feel like a ratchet effect when you tighten, so it slips at point it is sealed so you don't crush rubber seal. Not to worry as I see it.
