Re: convert to electric and clutch fan

I think you had mentioned it before, but what was the problem with the hydraulic cooling fan?
The hydraulic cooling fan setup is superior to the electrical/mechanical fan setup and gives less parasitic losses (so more hp)

Re: convert to electric and clutch fan

If you would remove the hydraulic fan solenoid, you will end up with a check engine light. Also not sure if you can just use the PCM output to switch the electrical fan. To me this conversion seems to be more of a headache then a cheap solution.

Re: convert to electric and clutch fan

There is a way to run a ford electric fan, but idk if the hydraulic part stays.

Re: convert to electric and clutch fan

I have been contemplating this issue also. I suppose it depends on just how
smart the PCM is and whether it would recognize the difference between the
solenoid and a relay. Both would show a closed circuit, the difference
being that the electric fan always runs at full speed, thereby cooling the
condenser at engine low/idle speeds.

Re: convert to electric and clutch fan

Maybe that the solenoid from the hydraulic cooling fan can be substituted by the pwm relay from the 99-03 electrical fan system. In that way the fan could work on multiple speeds, depending on the coolant temps.
