Cooling fan - Variable speed
« on: September 19, 2019, 12:45:02 pm »
Hi All.

I have a old Triumph Spitfire 69┬┤with an (build in) Ford V6 2,8i engine and Vems to control the engine and a single speed cooling fan, and it runs with no problems.
VEMS turns the fan on and off with no problem....

Now I would like to install a new radiator and variable speed cooling fan.
So when the engine is 85 degrees celcius the fan starts at wery low speed and when the engine gets hotter the fan accelerates, along with the celcius degree.
and finaly max fan speed at 100 degrees C.

Have anyone tried this and what relay do i have get, do I have to set the VEMS controller to ????
