240Z fan clutch radiator

[datsunnyit]

Hi all
the standard 240Z fan clutch for radiator fails.
Is necessary replace with new modern fan or 2 fans with thermostat.
Any experience, suggestions link for vendors.

The electromechanical thermostat or the electronic sensor (NTC), at what temperature has to be calibrated?

If a fan is used as recommended diameter?
If two fans who recommended diameter?
you have pictures?

other important info ?

thanks

Why not replace with another viscous unit? they're available on ebay.
Personally, I think the viscous ones are more effective and reliable than electric.

If you go electric, I think I had 12" and an 10" together. I had a thermostatic switch in the thermostat housing, right next to the coolant temp sensor. The switch was set at 88 deg I think. The switch is for a Volvo 240, and I had to tap the housing out to M14 to fit it.
something like this one: http://www.ebay.co.uk/itm/FEBI-0110...el:240&hash=item43f880503e:g:zpEAAOSw65FXr~JH
