checked this morning and it was screwed all the way down and when I unscrewed it I couldn't pull it off

another thing I notice is after I turn my Jeep off there is a hissing sound coming from the engine when I'm outside the Jeep like the its releasing pressure, it lasts for a few seconds and then its gone.

You can't get the radiator cap out of the opening? And open the hood before you kill the engine so you can listen for what is hissing when a helper shuts the engine off. My guess is the hissing is from the radiator cap leaking... if so, it needs to be replaced with a new 18 lb. cap.
