Dear Torana friends,

 

I wonder if there is a manufacturer who builds aluminium radiators with a thread connection for a electric fan switch ?

 

Otherwise where did you place it ?

Aluminum is the hard bit. Plenty of switches around but not a lot of ally bosses/nuts to weld in.

Best spot is in the manifold near the thermostat. Take a look at where most EFI systems put their temperature sensor.

 

edit: same place as the gauge sensor.

 I drilled and tapped the lower thermostat housing

fitted a 90-95 NO Switch for my thermo fans

Same.
Seems a lot of the older temp senders are
1/8 NPT taper thread.i.e you need a special tap.
Although I notice on the VDO sheets, there's now a few metric threaded ones as well.
