On each side of the block there is some small NPT plugs just forward of the bell housing that you can remove to drain the block. I have toyed with the idea of getting some NPT fittings with one end being a slip on fitting so that I can connect it to a water hose and really flush it out good that way. If you decide to do so, do it with a stone cold engine. Forcing cold water through a hot engine in that manner will do more harm than good.

Thanks kwik , thats what I was looking for ( an easy way to flush the block ) . What do ya think of the Cat antifreeze ? I think it comes premixed and you don't have to add csa to it .

I don't know enough about antifreeze formulations to be confident in the advice that I would be giving. I flushed my radiator out a while back and filled it up with Prestone green, a couple bottles of SCA for the proper cavitation protection and then found out that there is a Prestone black bottle that needs to be used instead. So now I have to take the first opportunity to flush it out again. 
You can be sure I will get it right the next time. I'll be exploring the Cat antifreeze myself and also Evans. Or I may just go with Motorcraft. I don't know yet.

I thought that the black bottle was just a pre-charged bottle of green anti-freeze, pretty much the same thing as just plain old green and the sca additive but I could be wrong. On mine I've flushed mine out real good and put the gold in and have had no problems at all. While I was at it I changed my upper radiator hose to go around the belt to prevent problems later.

prestone makes antifreeze for diesels that comes pre chared with the SCA additives. I have used it in my truck for 5k miles with no problems, oh ea it is green in color and is for the 01 and older.
