Fan Clutch removal

Anyone ever remove the fan from their 4.0L motor? Any tips? I know it has reverse threads. Just wondering if anyone had any troubles and or tricks to remove it.

Thanks
Rob

i didn't do it, but my hubby did. you have to remove the coolant overflow, that just clips onto the fan shroud. you have to unbolt the shroud next. there should be 4 bolts to do that. you have to remove the fan and shroud from the engine compartment at the same time. to remove the clutch itself, you need a spanner wrench. what he did was use a piece of angle iron w/ 2 bolts in it. you use that in the water pump pulley and then turn the big nut on the fan clutch itself.

Thanks Jessie.

I was out in the parking lot looking at it and was thinking a strap wrench on the pump pulley and a box end wrench the big fan nut. How did the angle iron and 2 bolts attach to the pump pulley. Did you drill it out and attach it to the pulley?

you gotta smack it off. find a way you can keep the pully from spinning and smack the pipe wrench or whatever you use with a hammer. once you have smacked it free it will come off easy.

there was 2 holes in the pulley that he stuck the bolts into. idk if it matters but it was on my '05 "X" 6 cyl w/ A/C. the pulleys should be the same though.

I understand what you did now. I'll have to look at it again, you're probably right.

I replaced mine two days ago .
Heres what to do get a big adjustable wrench and put it on the big nut on the clucth
and then a half inch (i think) wrench and put that on one of the pully nuts and twist it off that simple. by the way you will need a strap wrench to put it back on.
and you do not need to take off the fan shroud or anything els. once you have the fan with clutch attached out than you can seperate them and put your new clutch on and reinstall.

Jeep TJ 4.0L Fan Clutch

Good write-up and all you need to do is remove the overflow bottle.
They are reverse threads if I remember.

Got it!!!!
I used a strap wrench and a large crescent (adj end) wrench. It broke free quite easily. Thanks for the tips.

Fan Clutch Removal
1. Disconnect the negative battery terminal.
2. Remove the bolts that hold the fan to the clutch.
3. Pull off the fan and set it aside.

Use the large box end wrench with a 1/2" hole for a break over bar that comes in the fan clutch removal kit You rent from Oreillys. Put a break over in the wrench that fits around the sides of the bolt heads that hold on the pulley on for leverage. Then put the 36 mm wrench on the spine nut. Pull toward the drivers side with the break over and push toward the passenger side with the 36mm wrench for removal. Do the opposite to tighten. Tried to download pic of "wrench" around sides of bolts, with the fan off so You can see (not sure if it worked).
