Thanks all for responding. Brad the dual sensor is cool - way more
sophisticated than my set-up. I have one fan on auto and the ability to
run one or two fans manually. The truth is that I will probably leave
the set-up as is. If it gets on my nerves I will make a change -
probably making it switched. Just finished cleaning up my painless wire
harness on the entire car. I originally had the car rewired in '91. We
disconnected everything on the car, cut the wires to the proper length,
removed unneeded wires, and soldered/srinked tubed all connections. I
will post pictures on my web page.http://www.larrywilliamsstuff.20m.com/

the second fan. Have one fan come on at 190, and the second come on at 210.
That way you will lower the drain on your battery and still get max cooling
when you need it. Also, where is your sensor mounted?
If the sensor is in the head, this would explain the 9 minute run time as it
takes a really long time to cool down, and there is no water circulation
when you are stopped unless you install an electric water pump too! If the
tem sensor is on the radiator, then you will only have the fans running when
they can do much of anything about the temperature.

I have dual fans on my BB with a temp sensor in the alum head. The
sensor is set at 190 to activate. Currently at this time of year the
fans do not come on while the car is moving, but when I shut it off the
sensor will read a higher temp in the Alum head and start one fan and
run for about 9 min. I'm considering installing a higher temp sensor to
prevent the fan from running while the engine is off. Of course this
will effect running temps by making the fans come on at a higher temp.
How high of a temp would you guys allow the motor to get to before the
fan come on. I can run one or two fans manually if I chose
while driving
