In the real world especially Diesels and industrial engines these problems are very common and well known. Just Google them and look for some fun you tube videos. All Ford power stroke owners know about the cylinder cavitation erosion as the coolant flowed through the cylinder walls. Diesels use special antifreezes and/or supplemental additives to prevent the erosion problem. Similar to "water wetter".  However, the pure glycol approach is not the ultimate solution.

There should be no steam pockets in your cooling system unless it has not been maintained properly.  For steam, the temperature of the water has to exceed its boiling point at the pressure of the system it is in .  Your cooling system runs at a higher pressure than atmospheric, hence it can heat to a higher temperature without the water vaporizing.  If there is a leak in the system, then there may be steam.  But the leak is the bigger problem, and brings about overheating due to coolant loss.  If there is a leak in the system, the stuff being promoted will not prevent coolant loss and overheating.  it will just be a more expensive loss.

Shysters are really good at setting up false targets that they claim their product avoids.  Most often, those are problems that don't exist in the real world.  Have you had steam pockets in your cooling system?
