It's certainly a nuisance that the clamp wasn't supplied, but it's a very simple device that could easily be fashioned from a scrap piece of metal. Use my images posted above to get an idea of how it needs to be shaped and where it needs to be located.
It's not "mandatory" to use the clamp, but by not doing so you risk breaking the seal between the timing cover and the block. If that occurs you'd have a whole lot more work ahead of you.

The pulley is just held on with four bolts. Leave the belt in place until you've loosened those bolts.

Stupid question, I'm trying to remove the bolts but of course the pulley is turning !? What is the trick?
Concerning the clamp I've nothing to create this piece, where is it possible to buy one? Can I borrow it to a nice soul, I'll send it back directly after replacement and of course pay for shipping!?[This message has been edited by pommejaune (edited 07-20-2014).]

Notice that some of the water pump bolts extend into the water jacket. It is very important to use Permatex (or similar) sealer on the threads and apply a small dab under the bolt head before you tighten. Also follow the Torque sequence and torque tightening specs for each bolt. The Torx bolts can be especially fragile and should be replaced if they show rust erosion. Replacing the water pump and getting a quality leak free seal can be a tricky job, so take your time and follow the recommended procedure and everything will work out. When I replace a water pump on a 30 yr old engine, I also replace the cover seal gasket and the front oil seal but do not consider this unless you have the tools to pull the harmonic balancer.

As Patrick said, leave the belt in place until you've loosened the pulley bolts. You can press down on the belt with one hand to prevent the pulley from turning, while breaking the bolts loose with your wrench and other hand. Or, jam something soft between the belt and pulley, like a small piece of rubber hose. As it's pulled in between the belt and pulley, it can stop the pulley from turning.

Hello Dennis Lagrua, Firefool,
Thanks for the information, I've of course anti-seize and sealent ... but I'm still fighting to remove the pulley.
Firefool, I've tried blocking the pulley but this is not possible, the bolts are very hard, possible that they have been tighten with a machine?!
Is there another way to block the backward rotation?
My self-made clamp .... 
Thx

pJ, I'm afraid that "clamp" you made won't do a thing. The timing cover needs to be held absolutely rigid against the block when the water pump is pulled off the timing cover. Only if your water pump practically falls off will your "clamp" hold. Otherwise, there's a chance that the timing cover will pull away from the block, and the seal will be broken. It wouldn't take much movement to do that.

Yes remove the two bolts to detach the alternator from its bracket. And then remove the alternator bracket from the block/head.
And I know you're excited, but please delete the duplicate post.  [This message has been edited by Patrick (edited 07-20-2014).]

One bolt, as stated earlier in this thread.

I'll also mention that bolt # 4 in the diagram posted earlier is the only bolt that requires sealant on the threads. I used anti-seize on all the rest.

I recommend using Permatex® Aviation Form-A-Gasket® on both the gasket and the threads of the #4 bolt. I've used this stuff for 40 years.
