Review on Replace 15794103 Compatible Pontiac Saturn by Mark Adams

This is not a genuine GM or Saab factory part. My mistake was that I didn't notice the word "compatible" and/or "replace" in its description, nor did I notice the brand: Allmotorparts. It is made in China, although some AC Delco parts are also made in China. However, this cover will not work exactly like the original factory cover. After turning the factory cap clockwise until it clicks into place, a stop/lock will appear preventing you from turning the cap counterclockwise without force. This replacement cap does not have such a stop, but it does have the same spring action (albeit weaker) as the factory cap, holding clockwise pressure against it. On a positive note my Check Engine Soon light did not come on after a few days of driving which was the main reason (fault code P0442) for the purchase.
