I finally got around do doing this upgrade. Its really very easy to install the third radiator...its just messy as can be because theres no good way to drain the coolant without it going all over yourself and the floor. I guess if you have a real shop, its not a problem.

Also added some 1/4" opening, .065 stainless wire mesh for all three air intakes to reduce likelihood of a rock or other road trash damaging a radiator or a A/C condenser.



The wire mesh is very reasonable from mcnichols.com.

 

Good job well done.
