[DeTomaso] Flex-a-lite question

[michael at michaelshortt.com]

How long has your radiator been in the car?
Hoe many water/ antifreeze refills?
Do you use tap water?

I had an overheating problem, tried everything, then sent the radiator out
to be boiled. Went from overheating to being almost too cool, have not
turned on the aux fan in over a year.

I have the Hall Lay down 5 core unit in brass with two sucker fans. I use
my fluid mix of 1/3 100% Peak 2/3 distilled water and water wetter.

        I've come to the conclusion the Hall Pantera Meriah fans are
     getting
        tired and are not up to the task of slow traffic cooling.
        I say this because in Summer/Winter I now always see a large jump
     in
        temp when I get into city traffic versus highway travel. 20-30
     degrees
        jump. Wasn't always that way.
        I would rather not remount the three-pass Quella/Ron Francis
     radiator
        for sucker fans, so I'm looking at pushers.
        Felx-a-lite offers model 440 as a pusher. 2500 cfm, S-blades,
     etc.
        But I noted the online-available PDF installation sheet groups
     the 440
        pusher and the 420 puller in the same section.
        It instructs the 420 puller to be wired red/red and black/black,
     fan to
        power source. And to reverse the wiring to red/black and
     black/red for
        the 440 pusher model. This tells me the fan blades are expected
     to
        perform whether rotating CW or CCW. But I've always heard blades
     are
        optimal for one direction only, and show reduced efficiency when
        rotating opposite to the intended function.
        I will try to talk with a Flex-a-lite tech about this on Monday,
     but in
        the meantime I'm asking for any of your ideas, thoughts and
        suggestions.
        Thanks,
        Larry
        ......and no, I don't know why my emails (at least in the
     archives) are
        now getting duplicated by the List software.
