Help needed w/ radiator cap
 

Hi Guys,

9-3 Aero not driven since yesterday. Absolutely cold. I unscrewed the radiator cap to add antifreeze. It came right off, but I frankly don't see how to place funnel and pour. I'm thinking the outer cap came off easily and the interior part of the cap is stuck tight.

How the heck can I remove it to add coolant?

Thanks!

I have the same problem. It looks like the plastic yellow cap has become detached from a black inner cap; this inner cap is blocking access to add more fluid. I tried twisting off the inner cap with channel locks and a piece of the lip broke off. Didn't want to proceed further until I learn more. Anybody?
