4.7 hydraulic fan

so i have a 2004 wj 4.7. those have a hydraulic fan and i want to switch to electric but what i’m seeing is the lines that run to the fan also run through the power steering like a big cycle. so does anyone know a way to loop the system so you can keep using the power steering without the fan or does someone maybe make a line that will work. i have no idea thanks.

You have to replace the P/S pump with one that does not have the lines for the hydraulic fan. Also, doing this will set a CL light, but there are ways around this, one of which keeps the control valve in the circuitry or is replaced with a resistor.
