I ran a mid'80s police car oil cooler in front of the radiator like it was in the Crown Vic. The engine ran hotter than before or since I removed it. The frontal area of EB radiators is about 1/2 the Crown Vic radiator's area, so any blockage of incoming air cripples the cooling abillity. I may try remote coolers for both engine oil and transmission fluid, but I can't afford to put anything in front of the radiator where it often gets over 100 in the summer. For now the engine and transmission are doing OK. If I want to add AC, the condenser coil would also have to be mounted remotely. The good news is that EBs without AC are more comfortable than any non-AC car or truck I've driven, except my M38 Willys Jeep with no top.
