I didn't replace any hoses when I changed tha radiator because I put new hoses on about 1-2 years ago and they still seemed pretty good. Even with the engine running they don't seem to be sucking down like anythings pulling on them...but they don't seem to be pumping up either.
I'll go to my local Jeep dealership today and get myself a MOPAR t-stat. And I'll check my engine this morning and see if the system is pressurized. It was a cold night so nothing should come out of Rad cap.
