    So despite the 110* degree heat index today in Chicago... I decide that its a good idea to head out to the local yard to find my 2 new dual speed Ferd Elec. fans! Sure as hell was hot out there, but within a few minutes, I found two decent candidates for extraction. Went back to the car for the 10mm socket and wrench, yanked the fans, paid $50 for BOTH fans, and headed home! I still can't believe that I paid $80 for the junk "parts-store special 2200cfm fan!" The single fan that I installed on the front of the radiator (pusher) SMOKES the old electric I had!

    I still plan to install one more identical "puller" fan inside the engine compartment, but after a brief test in the driveway with only the "pusher" running, the temp. stayed down much longer than it EVER had sitting in the driveway! I actually held 210* for quite some time! That's unheard of with my BBC! I can't wait to see what I can do once I get #2 installed!

    As for wiring... I plan to have the puller run in "low" once swtiched power is supplied, and "high" will be triggered off of a thermostat with constant power. This way, the truck will cool itself off even without the ignition turned on.

    Having said that, I need to look into a dual batt. setup prior to winter time, so I don't have to worry about smoking a battery, and not being able to get her started! I dont know that I could push start my 6200lb Blazer by myself! /forums/images/icons/blush.gif /forums/images/icons/laugh.gif

    Looks like I will have my cooling issues resolved VERY SOON! /forums/images/icons/wink.gif

    The DONORS were both Taurus's... mid 90's. Only 2 10mm bolts to remove, and one electric something or other to break off to get the fan out. Other than that, I chopped the fan's harness after the plugs, so that I could still unplug them if necessary. I bought 2 30amp universal relays, 2 30amp external breakers, and will reuse the thermostat from the old setup to make it all happen.

    I am still thinking on how to mount the puller fan, but it'll come to me sooner than later! /forums/images/icons/wink.gif

    Only the pusher is installed... unfortunately, only the HIGH speed is reversable... so the pusher will only be functional if the thermostat kicks in! Otherwise the puller will always run in LOW mode, and will kick in high along with the pusher when the temp hits ~195*.

    These fans really crank. I can hardly hear the 454 over them! /forums/images/icons/blush.gif /forums/images/icons/cool.gif

    And to answer your question... they are ONLY used as pullers from the factory... but I learned quickly enuf that you can reverse the HIGH speed! /forums/images/icons/cool.gif

    What happens if you make a custom bracket that goes inside your shroud so you can mount it like a pusher, but its really pulling? Or just fab a shroud with this type of arrangement?

    Prob #1 - I don't have a stock shroud anymore... used the elec one, with no luck.
    Prob #2 - BOTH FANS won't fit on the inside... they measure 18" across the short side...

    I plan to make some kind of hangers for the puller, that will screw into the top of the radiator... and then something else that will locate the lower hangers to the factory shroud bolt locations.

    Also, having one puller and one pusher, I get better coverage than I would have using only one fan in its stock puller position... I'll give it a try. If I smoke the pusher from running it in reverse, then I'll have learned a $25 lesson that I can share with everyone else here! Otherwise, I gained HUGE cooling capacity. /forums/images/icons/wink.gif

    I've got the thermostat jabbed thru the lower driver's side of the radiator fins. The POT that controls the temp. trigger for the fan is attached to the driver's fender for now... I might move that over to the pass. side tonight.

    Think that's a good place for it, or should I locate it somewhere else? /forums/images/icons/grin.gif
