Elec Fan Radiator Sensor.

One thing I have see if you don't won't to place a hole in the radiator is 
to cut the top hose and place a piece of copper  tubing with a 
correctly-threaded bung and sensor in the middle of the hose.  Check with 
one of your local plumbing contractors for a short 6 to 12" piece of copper 
the size of your upper hose, they may give you a short piece they have 
laying around and might solder it for you, otherwise you will end up buying 
a 10 or 20 foot section from a hole sail house.  That's if you need a wet 
sensor, they have clamp on, type also.

Couldn't you get a sensor for a newer car, and add a correctly-threaded bung
to one of the rad tanks??   Problem is that most new car sensors are set
pretty hot.   Wonder if any import parts places (like Bap-Geon) have any
cheap universal thermo-switches?   Just had to buy a rad fan switch for my
Audi -- $54 thank-you-very-much.

I put the radiator in the American this weekend with it's electric fan in
place, Tight fit!.
I have a relay wired up in the relay center to power it.
Now I'm trying to figure out how to trigger the relay.
No place in the engine to add a sensor that I can think of.
My options are, to use the relay I have in place and trigger it with a
switch. Then I would add one of the adjustable t-stat systems as a main unit
and use the switch as backup.
The other thought is to get a piece of pipe and put a bung in it and use a
threaded snsor to trip the relay.
   Anyone have any thoughts on any of this?
Anyone know a good source for a threaded fan switch?
Autotronics makes a nice one that has a ground wire that would be needed
with the radiator hose mount, but the sensor itself is $80!

Thanks, guys
