Re: Elec Fan Radiator Sensor.

I hadn't thought of Copper tube.
I may be able to find a piece here at work as there was some large pieces left after the last renovation.
I think I may try mounting a wet sensor in the return hose. As long as I keep it down around or below the 210 degree range it should be fine. So I'm thinking that if I pick up one of the G.M aftermarket wet sensors that trip at 195-200 range they will kick on when the returning coolant gets to the point that it needs the fan on.
I know 87-90 XJ's had the sensor in the radiator tank close to the return hose, IIRC!
  If I had thought of it I would have had a bung added to the lower radiator tank, but it is in and mounted and I fooled with it all last weekend to get it  how it needed to be with the G.M electric fan on in. I'm not pulling it out again!
