Electric Fan Users. Quick Question.
Just curious for all of you guys that are running electric fans that are mounted to your radiator on the inside (pulling air through radiator). Since the core is in at a angle and the electric fan/fans point down towards the ground not the engine has anyone built or created any kind of air deflector that could be attached to the front cross member that would divert the air to blow across more of the motor and exhaust? Maybe this is a stupid idea but the factory shrouds direct the air flow to go across the motor? Just curious? Would it help vent heat out from under the hood better than just blowing straight down?

The water pump where the fan is mounted is directly in front of the motor so this is where the shroud is. It has nothing to do with the fan cooling the motor. It does little if anything blowing air onto the motor.

One other benefit..........
James,
I have a single 16" fan on a fibreglass shroud that I built myself. The fan is parallel to the radiator and of course blows down at an angle. Because of a Bubba'd "cut and shut" job on my transmission cooler lines, I cut the steel lines off near the fuel pump and used compression fittings to add new lines.
However, instead of going to the radiator, I put a 90 degree bend in both of them and ran them to one of those cylindrical transmission coolers with the radial fins. I mounted the cooler transversely just in front of the cross member so that the electric fan blows on it when the engine gets hot enough to switch the fan on. At other times, it relies on air picked up from under the car.
The system seems to work OK, but I haven't driven it on a hot day so far, but I can't see why it would not work. I don't believe that you need to have hot air blowing all over your engine if you can make it blow under the engine. The engine will get all the heat it needs from the burning of the petrol and the water in the jackets.
Hope this helps.
