Replacing with an electric will not save you any power. yes you get rid of
the fan running from the belts, but you at an huge load to the alternator in
return. So you don't save power you just loose it elsewhere.
It doesn't put as huge of a load on the alternator as the mechanical driven
though. Many people who have does the swap report they can feel the
difference and dyno results in a couple hp gained. Flex-a-lite makes a
model specifically for s-10's and someone on one of the s-10 forums
installed the flex a lite dual fan.
"An huge load..."
Care to quantify?
I use electric fans on my hobby cars. I notice no "huge" loads on the
electrical or charging systems, even on older cars('70s).
You don't really gain that much in HP, but it certainly does free up a
little power and it's only about 1000 times safer.
I decided to switch to electric fans after watching one of those real-life
ER shows on Discovery channel. An older black gentleman came in and he has a
flex-fan blade embedded in his forehead. It seems he was tuning up an old
ford or something when it broke off and buried itsself in his head.
Since then, nothing but electrics for me :-]
