'99 ram 1500 van water pump replacement

I'm attempting to replace a leaky water pump on a 1999 Dodge Ram 1500 Van
with the V6. I can't seem to find any way to lock down the pulley mechanism
in order to remove the viscous fan assembly.
I can see 4 concentric holes in the face of the pulley, but I really don't
see any way to lock into them to spin the 39mm nut without both mechanisms
interfearing.
Any help is greatly appreciated.
Thanks

I usually leave the serpentine belt on, put a big wrench on the fan nut, and
strike the wrench with a mallet.  The friction of the belt, combined with
the sudden impact on the wrench, usually breaks the nut loose.

Conversely, I re-install the fan first, holding the fan stationary and
turning the pulley to thread the spindle into the fan clutch, then
re-install the serpentine belt, and whack the nut once clockwise to tighten
it.

Absent the special tool to hold the hub, Tom's method works just fine.  If
you find that the hub still turns instead of the nut, you can create extra
belt tension by depressing the belt between the pulleys.

Thanks gents I'll give both a try.
As far as I understand it, the thread is reversed so I need to wack the
other way, yes?

No.  Right hand thread.
Just did one Friday.

Good to know, thanks.  My books say reverse thread - imagine how much fun it
would be following those instructions!

So thanks everyone for their input.  At the end of the day none of the
suggestions panned out so I got a pneumatic hammer and used a pointed chisel
to break the friction.  Worked like a charm!
Thanks again for the advise.

You need KD Tools #3471 (universal pulley holder) or #3472
(pulley holder and wrenches) as pictured here:

http://www.mytoolstore.com/kd/kdengi06.html#3471

If there are no bolts holding the pulley to the water pump hub,
you can slip two bolts thru the holes you mentioned and then grab
them with the universal pulley holder.

Autozone, NAPA, etc may have these to loan or rent...
