How do the auxillary fans on the radiator work?
Mine do not seem to be coming on. And the temp guage goes from about 180 then drops completely back
to cold.

The fans work with the temperture if the temp gets too high the fans go on. They will also go on with turning the ac on. With the temp going from normal to cold then replace the thermastat. It keep the heat in the range of 160 to 195 degrees. With some models even ranging higher.
