...... Im using 12-pt wrench, the only thing that will fit behind the clutch, I dont have a 6pt box end wrench.
A ratchet will not fit so forget using any type of stripped nut remover...
....Or how do I get the nuts off?

This is probably too late to help you now, but you might want to consider purchasing a set of Irwin Locking Wrench Vise Grips for the future - Item #8 - 4LW (4 inch in size) & Item #4 - 7LW (7 inch in size).

Wrenches | IRWIN

Constructed from the highest grade cast iron, forged and heat treated to ensure maximum durability, IRWIN® Pipe Wrenches are made for a variety of uses on the jobsite.

These Irwin Locking Wrenches come in handy when trying to remove stuck nuts & bolts. I've used the 4LW wrench / vise grip many a times loosening stuck fan clutch nuts along with stuck brake bleeder screws. The 4LW may be small in size but it fits in tight spaces and it's got the grip to remove any stuck nut or bolt I've run across in those tight spaces. The 7LW doesn't get much use, but it's there in case the 4LW is too small. Something to consider purchasing for future use....

I use a home-made extra long 10mm wrench, or the one someone made for me.

Ironically I searched Autozone online first for these studs. Nothing came up in the search. Their search is really bad for a company of this size.
The autozone nuts look like real metal too. These stock Nissan nuts I think are made from lead. There is no wrench that would work on these, they are doomed to be rounded off as the nut is going to round before the threads let go. It is a tug-of-war and the nut corners lose with such poor quality metal.

All done.
The fan roars to life upon start-up.
Then settles down, but after 30 -60 secs is still more roar than a cold motor needs. That's all the patience I had to wait right now. Will see how it does after a drive.
I put 40cc of oil in the clutch. No idea how much it takes, but not more than 40.

ebay oil

Mom's vehicle needs a new fan clutch. I realized after all this that it is not her AC coolant, but a hot engine. I will try to rebuild hers too. Chevy vehicle, so no idea on details...

no pics. not much to show except an open clutch.

That vice grip looks interesting, I had not seen one like it.

I usually interlock two wrenches if I need leverage. If I need more I have a good selection of pipes

Keep in mind the nuts were not stuck because of lack of torque, they were stuck because they rounded off. The little tiny 10mm wrench was all the torque it took to round them off. The metal was just that poor. A longer wrench only makes it easier to round them off, does nothing to remove the stuck nuts. Heat did not work, penetrant oil did not work, they had to be cut off in this instance.
thanks

They don’t round off near as easily if you use a 6 point wrench. I have never had a anything strip when using a 6 point because the grip is just too strong. I have had plenty of items strip when 12 points are used. That is the real solution here prior to starting the work.

I would strongly suggest for some folks to invest in better quality tooling.
For what you save DIY for a single job, you can add significantly to your toolbox.
If you have the right quality tool, you eliminate 99% of your troubles, and you won't be blaming the fasteners.

You are right on man, smoking like you got em... Quality tools are amazing. Invest, or at best find something at the flea market bin...

I find this Vise-Grips really handy, even for plumbing, Model 12LC. The Original™ Large Jaw Locking Pliers - Tools - IRWIN TOOLS

They're not the only ones !!! I needed a certain type of Glidden paint, knew Home Depot is their largest distributor. So I tried searching homedepot.com for that type of exterior paint, could not find it. I finally typed Glidden GL9611 into Google and then located it at the local Home Depot !!!!

Please see post #20.
M6 x 1.0 is correct.

Oh I dont know how I missed that, thanks a ton!

M6 x 1.0mm for sure, 10mm wrench. I didn't have ANY issues with my fan clutch nuts rounding on either my 1998 or 2004 Frontiers. I used to use blue Loctite on these, but then it was more difficult to simply unscrew the nuts after initial loosening, so when I swapped in new warranty fan clutches on both those this summer, I didn't use Loctite or sealant, just the 6mm nuts.

I would guess the truck with the rounded-off nuts had cheap aftermarket nuts on it....
