Fan in front of the radiator pushing air toward the engine.

I stand corrected , it is better behind the rad pulling. Don't know what I was thinking.

Bob,
Check the manufacturers specs on the fan. Most of the fans have a better CFM rating in "Pull' over "Push". I have a 2950 cfm Pull, mounted engine side of radiator, with a shroud. I have a 1900 cfm Push, infront of my radiator/condenser, which I use with the A/C or as a supplement.
Good Luck,
Bob

Hey thanks Bob,
The cfm is rated as 2450, I did read somewhere that pulling is better. I 'm rethinking as where to mount it, It will be fine inside engine compartment.
Thanks again, I really like this sight,,

IMO I think it's better to have it in the engine bay between the water pump and the radiator, pulling air through the radiator. Use a fan shroud if you can. I believe this is the most efficient way for a fan to work. (in most cases)

Doc here,

Mounted in the Engine Bay, Pulling air thought the Radiator..on to the engine.

Is not only The Best way, But the Way MOST Stock locations are mounted.

SOME of the pluses are,

• Better Cooling through the Radiator, From cool ambient air,
  More rigid Air stream on the Block and to evacuate the engine bay of static heat,
  
• Doesn't Tend to "Block" or break up air flow in "Off" or "Inop" Conditions through the radiator,
  
• Road "Fodder" (like plastic bags..ect..) Is least likely to become trapped in the blades.

Just my humble opinion..

Cool, no pun intended..
