I am looking to install an electric cooling fan switch in the upper thermostat housing . anybody know where to purchase one, and what temp would I want for the fan to come on with a 180 degree thermostat .also what about the thread size if anybody knows that . thanks

You can buy a simple thermostat kit and the thermostat switch should fit in the position for the thermotime switch on the 280ZX thermostat housing.-

I think the sizes are as follows. You should be able to find a M12 easy enough or tap the 1/4" out to 3/8" NPT.

Temp gauge: M16×1.5mm

Thermotime: M14×1.5mm

Water temp: M12×1.5mm (for fuel injection control)

Water temperature switch: 1/4" BSPT. (Not the same as NPT. Has 19 threads per inch and NPT has 18.)
