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
 

Did it run hot before you found the fan clutch failure?  Can you replace the fan clutch?  

I replaced both fan clutches on the two 240s I've had along with a new water pump and thermostat.  The needle points straight down, south.  175 fahrenheit.

The one I have now has a 280Z radiator and full plastic shroud off a 280ZX.  It runs 170 fahrenheit.

It's a lot easier to install a 280Z radiator than more electronics like the fans, to me.  The only drawback is the 280Z radiator hangs down 2 or 3 inches more.
