13.  Remove the radiator by lifting it and pulling it in a rear direction. Disassemble the lower mount from the radiator core support center. 

NOTE

Because the air condition condenser is onto the front lower portion of the radiator, moving to the rear direction should be kept at a minimum.

since the core support is there is must be moved to the back. You wont lose the freon but just have to work it too the back being sure not to damage the lines for the ac.
