No they were indeed referring to a hydraulic fan. Some year WJ’s have a hydraulic fan that runs off of the power steering pump, my old jeep had one. It also had a smaller electric fan.

 

[TazRango]

That's bizarre. I've never heard of that before. I thought they were referring to the viscous clutch in the belt fan...

 

[Dakota4Me]

Ya, it’s a really strange setup. It worked great on my Jeep but it also turned something non-critical into a crucial component and I don’t know about you guys but my power steering ALWAYS leaks. . . Even after I “fix” it.

 

[Muddy maki]

Clever idea. I was thinking of ditching my mechanical fan any way. Question though. Is the clutch to pully mount reverse thread? I think if I do this I might just space back the upper shroud instead of taking a chance on leakage.

The threads are normal right hand threads.

I forgot to mention too,there's one thing I think this mod needs to be truly complete. It'll probably take me a couple of weeks to get to it but I'll be sure to post it up when I get it done.

Soooo....... it's been a long couple of weeks huh? LOL

After doing the swap,the first thing I noticed was the open threads on the front of the water pump where the clutch fan used to be. Like this....

**Click Pics to enlarge!**

Well that just screamed "cover me with a billet cap!" I looked all around and never found anything,so I made these.

As seen,I made extras. I kept one,one has been traded and the other two I would sell. And if needed/wanted I will make more. Open offers,I'm not sure what they're worth. They are billet aluminum and they are threaded to screw directly on the pump. Not just a cover held on with a set-screw.

Do you still have the pictures? They aren't showing up and I'm interested in ditching the clutch fan.

 

[Racer 1966]

Sorry bro,I'll have to get that worked out. I used my ISP's service for web storage and now they have done away with it and didn't even notify me they were going to. EVERY pic I have up EVERYWHERE is gone. I'll have to locate them and get another host set up ASAP.

clutch fan delete, switching to grand cherokee as primary

What year/submodel/engine size did the grand cherokee fan come from?
Just out of curiosity, was it new or junk yard? And what was the cost? (if you don't mind)
"Plugged right in" - what plug? (someone mentioned a/c-pcm plug?) But since I plan on keeping the tiny a/c fan and replacing only the clutch fan (on water pump/pulley).. there is no free plug that I know of floating around in the engine bay to plug this e-fan in to.
Not to mention I would probably use a fan controller for something below +210*.. since I plan on running the JET 180* thermostat. Unless someone knows the optimal temp to run the fan at? (maybe a 2 stage (diff temps IDK? maybe [email protected]* [email protected]/215*, off at 190*) That's a whole other page)
Anywhoot, let me know when you can.

TL;DR
I too want to do this and can't wait until your photos are back.
There were a few specifics I was curious about ^
Is there an "optimal run fan/on temp" for the primary fan in the OE/Stock setup?

Pics are back up..

You can't keep the stock e-fan and put this on top of it, this replaces the stock fan and plugs into the stock harness where the old fan was. If you use a tuner (SCT, Superchips, etc), you can reprogram the stock setpoints for the fan and not have to use an aftermarket fan controller.

I can't tell you much about the fan itself,I purchased it used from caulk04 here on this forum. Cost me $50 if I remember correctly. This fan will NOT fit with the original a/c fan. I pulled it and that is the plug I am using. Eventually,I will get some pics/specs posted on the mounts I made when I pull the engine apart for head gasket swaps. May even make/sell some if someone wants them.

NOTE: The head gasket issue existed BEFORE this swap was done. I haven't noticed any issues yet just using this fan. I just have the stock temp gauge and it moves very slightly higher before the fan kicks in. Nothing I'll worry about.

Since my pics are gone from my update post,I'll mention it again here. After doing this swap it will leave bare threads exposed on the water pump. Since a lot of people like to dress things up,I made these caps to screw on and make it pretty. And I'll sell those too

 

[TazRango]

It's a 1999(?)-2002 Grand Cherokee 4.7. Part number is CBG4F250.

Actually I'll put that into the OP for you too.. :wave:

I am still deciding whether I want to do this fan or the Taurus fan, so I may want a set of brackets.. But what are you asking for those snout caps?

 

[mopar_man2013]

A fan like this?

Just for reference

Or this?

First one is right, but it includes the shroud which you don't need so theres no sense paying for it.

Second one is no good - in fact it's illegal for him to be selling it because it has been recalled. You want the one with an AB or AC suffix (2nd or 3rd revision), or the number I posted above.

The search results for your item number turned up zero on ebay. My luck. Haven't had time to see if any forum members have one for sale. Thanks for the extra clarification.

 

[TazRango]

There's a lot of hits off 52079528AB.. Just don't buy one that just says 52079528 without the suffix.

 

[Racer 1966]

How about $25 shipped for the pump snout caps?


Should someone call them out for the recalled part on eBay?
