Hydraulic fan replacement how to?

Ive spent all day searching and yielded nothing so far.

So I was trying to replace a power steering hose today on my 4.7 Limited and I stripped the hydraulic fan module. The high pressure hiose connector is still good, however the threads in the module are smooth as butter. I was able to find the replace module and frame from a salvage yard without spending a $1000 plus for a whole new radiator/fan setup from Jeep.

I was wondering if anyone has a how to guide to remove and replace the hydraulic fan system. All i could find is the electric fan removal guides.

Re: Hydraulic fan replacement how to?

Welcome to the garage.
I removed my hydraulic cooling fan when I replaced the radiator. The fan assy is mounted with 4 bolts to the radiator. The two upper bolts are easy to remove, but the two lower are not. I remember that it was easier to remove/install the whole radiator/fan assy as a complete assy and then split it, but ofcourse I had to change the radiator in the first place.
So probably in your case you just remove all hydraulic lines and the connector and then first remove the two lower bolts. They are difficult to access and can only be turned a little bit each try. If both lower bolts are out, you can easily remove the upper two bolts and remove the fan assy.

Re: Hydraulic fan replacement how to?

Ok, only seeing now that you have the whole radiator/fan assy already out. It is maybe even possible to do a thread repair of the fan motor with a helicoil insert.
If you still want to change the fan assy, did you only get the motor itself or the complete assy?

Re: Hydraulic fan replacement how to?

It is quite simple, but not that easy. As I wrote before, the lower bolts are difficult to access and to get out. For the rest its quite simple. After installation you could remove the coolant sensor connector to let the fan go to full speed, and to get the air out more rapidly.

Re: Hydraulic fan replacement how to?

I only forgot to mention that disconnecting the coolant temp sensor connector will give you a check engine light and a fault code, which has to be reset afterwards.

Finally got everything fixed. After I replaced everything the damn pump broke so I ended up replacing that too. But those bottom bolts on the fan were a pain in the butt to get to..
