I need to replace my fan due to damage on the old one. Can I do this without removing the fan clutch. It looks to me I just take off the 4 bolts on the back and might have to remove the shroud. I tried the search but only found the fan clutch removal. Thanks
No, you gotta put the fan removal tool on the nut behind the fan, and then spin it off. I wish it was that easy as pulling the four bolts (unless I've been doing it the hard way all along LOL)
If you do have to remove the fan and clutch here is a video of water pump R&R. The first part shows how to remove the fan and cutch assembly and tools needed. LINK
Ok, thanks guys. I got the part on order so will be doing it next week. I still don't quite understand why you can't remove the four bolts. Don't those hold the fan on to the clutch?

the fan mounts to the back of the clutch so the clutch had to slide through the fan before you install the clutch on the water pump.
Order of removal for me:
1: drain and remove coolant tank, you could try clamping off the large hose running from the tank to the radiator but you may have to drain the radiator enough to get the water level below the opening in the outlet of that hose.
2: disconnect fan clutch from water pump or just break it loose so it's only held on by a few threads
Spin it on/off with an air hammer. It's not that tight.
huh? yes an air hammer would get it off in a pinch but a fan clutch removal tool can be borrowed or made pretty easy. Sometimes even a strap wrench can get the job done.
I am not too sure I would want to hit my water pump and fan clutch with an air hammer , or any kind of hammer for that matter. unless I had exhausted all other solutions and it was seized.
To each their own but the fan only needs a tap to come loose. Just trying to save someone the aggrivation of tracking a special tool down.
BTW - this is the way i was shown buy a certified navistar diesel tech.

Thanks for the tip. I might do it that way. I read in another thread a couple of guys recommended doing it the same way.
I had to change my water pump in the driveway, so luckily I had a piece of 1/8"x4" steel laying around, I cut it out to make a wrench for the nut on there fan. The belt held it pretty good to loosen it. I just disconnect the screws holding the coolant container and swing it over in between the battery and a/c compressor and then loosen up the shroud, and you can either drop it down, but it's easier to pull it up and out. Once you do it the second time only takes like 10 minutes. I can now pull a turbo in about 20 minutes LOL- it gets easier with practice

Thanks for all the advice guys! I was hoping not to drain the reservoir. It seems like a pretty easy job once you get the fan clutch off.

good to know, the more I think about it the better sense it makes. Thanks for posting!!
