Yup, this thread is missing any discussion on LOCATION. LOCATION plays a big part... good luck over cooling that aw4 in southern california, or tucson where the OP is located.
It wont be this forums first facepalmable offense, nor the last!
Actually... I did point out where I mounted mine. Or, I should say re-mounted it during my "perfect engine temp" experiment.
The reason the factory mounts the aux cooler below the radiator is to keep it out from in front of the radiator. I know, I know, duh.
But, mounting it in front not only blocks air flow, it partially preheats the air going across the radiator. Moving mine out from in front of the radiator to under it gave me an immediate 5C drop in average engine temp.
