Regular maintenance and using quality fluids goes a long way in preventing core failure. This is one Of the reasons I use JD Coolguard or Coolguard II, it has the least amount of metal loss and can be used in any system that I am aware of.
Check out the loss of metals due to erosion especially the aluminum.
