Good suggestion. The grille is clear, and the condenser is, in my opinion, quite clean: no bugs and just a few rocks (the are behind the aux. fan is clear too, as is the back side of the condenser and the front of the new radiator). Attached is a picture I just took of the condenser.
maybe replace that one with an OEM one, 16 lb comes out to about 1.1 bar. the OEM specifies a 100 cap (1 bar). worth trying since you've done/tested everything else. the 100 cap will make the cooling system run at a little lower pressure
