I used a Hayden fan controller on mine it has a clip and a push in type sensor for the rad.

 

Ya, I had a probe type sensor on mine and the probe lost its resistance so the fan is on constantly now. I would like to replace the bleeder plug on the upper coolant hose with a screw in sender. I just don't know the size of the bleeder plug.

 

OK got you and understand. its not a hyden is it because they have a lifetime replacement on the just giving a heads up if you do.
