Where is a good location to utilize a coolant thermostat for a set of electric fans. Is there a port to use or am I going to have to fab one???

Any other ideas. I was thinking maybe a tee fitting were the coolant sensôr goes.

I was told not to do that, the logic being that either you'd have to deal with it becoming an air pocket, or the coolant wouldnt actually be flowing past the sensor, creating a "hot" spot. Not sure how it would all work out, to be honest.

You could have a bung welded onto the upper radiator pipe, or use a radiator hose adapter from Summit, too.

Well then maybe the heater line that comes out the top of the housing. I tapped mine and used an fittings cause I was tired of it leaking I could put a tee there and put the thermo there

You mean the turbo coolant port?

No the turbo port comes out of the large radiator steel tube. The o ring fitting with a 90 on it that comes out the top of the thermostat housing. I always tap mine and use an fittings cause I have had problems with them leaking. But I could weld a fitting n the large tube also and come out we're the turbo line used to

Oh ok...gotcha. Ive been trying to find a 1-3/4" or 2" radiator hose adapter, but seems they arent made that large.

I got a 2 in steel hose splice barb. I might drill it and weld n a fitting instead. It should work fine in the top hose I hope. I need to extend it anyway since I relocated the rad. Anyway so I have to extend it. This seems the easiest.

Fab shop on my route told me they can do something similar when I am ready for it. IIRC, the switch I was looking at was M22 (huge), but they said they could do it.
