on the head? I just installed a be cool electric fan on my SBC 283. I have a sensor location on the intake manifold for the temp gauge. I need one for the temp switch now also. I was told there is another location on the head.

There should be a location between the center two exhaust ports-

I tried that port on the head--fans would never shut off--my thought was that the switch is sensing the head temp and not the coolant temp--

If you have to use the adaptor that came with the switch>>>the sensor probe does not protrude into the coolant flow.

If you have another location on the intake maifold--(I would put it there)

Well I have another spot behind the carburetor but I wasn't sure if that taps into the coolant. Any idea if it does cause I would love to use that spot.

Head located sensor will indicate hotter, a good sensor switch is adjustable for that purpose.

I am pretty sure that the tapped hole behind the carb is for vacuum.
Power brakes, Tranny modulators, Vacuum Accys. etc

If you have no sensor plugs in the heads between the exhaust ports,
and only 1 hole in the front of the intake (that is not used by the heater)
You may be able to use a thermostat housing with sensor holes in them.

I am not sure how this would work----but you give it a try

(if you don't want to use the head route)

Yup it seems the intake one is the only one. I did think of maybe drilling a hole in the neck and tapping it. I'll have to check and see if they sell something like this already. Thanks Bryan!

No need to do that, just purchase a t-stat housing that has a 3/4" NPT hole in it for a sensor.
