Pusher fan(s)

[Rapid Roy]

Wondering if anyone has added radiator cooling pusher fan(s) using belt driven fan or electric radiator fan. For instance adding one or 2 smaller fans in front of AC condenser for added cooling.

I did on my old Jeep because it always ran hot with the AC on and having no EGR. Worked great for bringing the temp down in the summer. Never needed one in one of these trucks.

Seems to me that a pusher fan or two mounted in the front would actually reduce the surface area of the radiator

The factory did this in many trucks powered by big blocks.  The single ~12" fan is controlled by a temperature switch installed in the right cylinder head via a relay mounted on the firewall.  I added one to my SBC with A/C and enjoy excellent results.  I wired mine to integrate engine overtemperature with A/C overpressure controls.  The forwardly mounted fan does not appreciably disrupt air flow through the radiator when idle.  I recommend this upgrade, especially when residing in hot climates.

My only issue is I can only add 1 or 2  9" fans in front of condenser due to the limited space because of the hood latch bracket. Bracket is at an angle inward from top to bottom and this is primarily due to that is where the grill mounts. I measured 10.5" on each side of the bracket and not much room for one behind bracket. I believe a 10" would be too large.

Here's the factory setup BD is referring to

As I mentioned about the limited space I have, if I mounted 1- 9" fan to passenger side should it be placed at lower corner of the condenser or centered?

Mount it for best fit.  Choose the fan based on CFM flow, the greater the better, but be realistic about advertisers' claims.  Any chance you could install a larger diameter fan?  If I get the opportunity, I will snap and post a "through the grille" pic of what I run.

Thanks. Cannot really get one larger due to the space. No room behind hood latch bracket.
