Is a dual radiator cooling fan really that helpful ??

[southdave]

Clutch fan will outflow any electric fan that would fit. For a CUCV that's the best way to go IMHO. Electric fans are used on new trucks solely for emissions / efficiency reasons. I've used them in the past on hot rods where throttle response was important. Doesn't really matter on the old 6.2

Have to agree with Astro, the radiator is really taxed wirth atf cooler and engine oil cooler integrated into one hear sink... the engine suffer from uneven cooling and higher temp generated from IDI injection.
