Radiator
 

What is the piece that holds the radiator called?

Are you talking about the radiator core support?

That might be it. Im looking for the piece but didnt know the name and didnt see anything that looked like it would be it.

Could you take a pic and show us so we know exactly what part you are referring to?

Once i get home from work ill go out there and take a pic im just making sure i hav everything

is this the piece that holds it on or there another piece?

That is your upper radiator support. Just type in the info for your jeep and radiator pupport.
