John, sounds like the problem I had. You can try flushing with radiator flush or more drastic dilute muriatic acid (some might advise against this). My block was so full of scale I had to take the head off and clean the sludge out manually and with a hose. Of course it could be a much simpler probelm like a blockage in any of the water hoses, a broken impeller etc. I presume you've checked all the obvious problems. I found a huge chunk of silicon in the outlet hose from my water pump for example. Take off the water inlet plate that goes into the block and run the engine for a few seconds. Water should shoot out of the pipe coming from the water pump, if not your problem is upstream of here (although you still might have a partially blocked block of course). When I took the inlet plate off the block I found an almost solid 1-2 inch wall of scale impeding the water flow into the block. For more related info check out the previous discussion below.
