I manufacture a radiator fan controller here in Southern California for a Datsun shop called Mikes Z Shop in Whittier. The owner's name is Mark and he has a web page at www.mikeszshop.com that has been purchasing my controllers for about a year. He has found that these controller work and has just about zero problems except when audio radio shops mis-wire the controller and it stops working.
He has a lot of Z owners and other cars that were convert to an electic fan controlled by Auto Cool for best cooling in the summer and cars with after market AC systems.
This controller is very simple and easy to install and you can mount it under the hood, under the dash, or in the trunk. It has a black knob on the front that you can control the operating temperature of your radiator.
This first Auto Cool is a on off controller with an internal 30 amp relay. I am working on a pulse width modulated that is pure analog NOT A microprocess based controller. I will be having the printed cirucit board started in a few days. The prototype has been completed - now to get the package completed and into the market.
