    If You Have to
    My '92 SC400 was leaking cooling fan oil. It never completely shit out, but I thought, "Why not?" So I paid like $500 for this electric fan that while is lighter, does not keep the motor any cooler. I haven't noticed any kind of gas mileage increase (still at 23 on the highway and like 17 in town) or any kind of power increase (although it must be said I didn't expect much, but the forums gave me a bit of hope). I suppose this conversion is fine, but if my OE fan wasn't dying, I wouldn't have bothered. $500 is $500, man.
