Today I swapped my 4.7 wj over from a hydrolic fan that gave me issues with high vibrations. To an electric mid 90s ford Taurus fan(high flow rate)
The biggest problem is I have a tow package so it's linked in with a extra cooling radiator and then ran threw the fan. I went down to the local junk yard and pulled a pump off a 4.0 wj (has the same mount but different hoses that all fit the same steering box. But it has no hydro fan. Then I just swapped it in and am going to make a mount for the taurus fan out of the shroud of the old fan. Currently running with no fan till I finish the mount and electrical set up (running to a switch into the cab)

 

Massive! Increase in steering power! So much easier to steer! The old pump is for sale for 30 buck it was swapped out less the 7000 miles ago the guild was still new colored so pretty new pm if interested

 

I know this is an old thread, but Im new to the Grand Cherokee, and I have run into the Hydro fan failing on me, now I would like to go this same route but I got a few questions.

1st. Can I use the same power steering pump? Basically it has a high pressure output and a return line, so I'm thinking of just routing the 2 line thru the steering box and eliminating the hydro fan, and cooler.

2nd. Can I hen just go with an electric OEM fan, should be same size from the Laredo WJ right?


Thx

 

My 04 4.7HO came with both fans.

 

what a mess! I can see why anyone would want to change that out.


I recommend using a solder gun to make cuts to fit the fan. much smoother and more precise than a saw.
