>The fan that is on my red Spit has the following note in the installation
instructions:
"NOTE: These electric cooling fans are designed to PUSH or PULL
air,
depending on the installation. Fans are preassembled in the PULL
configuration. If your application requires that you push air,
please follow the steps listed below-
(A) Remove the retaining clip "C" and fan blade.
(B) Turn the fan blade over and realign to properly fit over the
roll pin in the motor shaft.
(C) Press fan blade in place and reinstall the "C" clip on the
motor shaft."
The installation onto the radiator makes the fan motor face the radiator in
either case. So Reversing the blade id the only thing that is required to
make the thing push or pull as required.
I'm still stickin' to my story!

Here we go again. Instuction manuals with omisions. Did they describe the
wiring? The wiring must be polarized to rotate the fan in the correct
direction.
Try an experiment:
Mount the fan on the bench so that it is facing you. Since it is
configured in the PULL configuration wire it up to PULL air. Observe which
direction the fan is turning. Let's assume it is turning counter
clockwise. Now reverse the blade. Without reconnecting the wiring power
it up and see that it is still turning counter clockwise. Also note that
it is still pulling air. Also notice that it is now moving considerbly
less air than before. This is because the blades are not rotating in the
direction they were designed to turn. In order to make it a PUSHER you
must ALSO reverse the wires.
So, it is 1 AND 2 not 1 OR 2.
BTW Congratulations on winning FTD! :-D
