I have read a few post on changing from green to gold coolant and was curious about the advantages?

There are better coolants than the "Gold".
I recently spoke with a cooling system engineer at Ford. The Gold is Ford's universal coolant that they use in all their vehicles now, mostly gassers. Apparently the "one size fits all" approach simplifies owner and Ford tech confusion, reduces the different types of coolants Ford shops need to carry, it's convenient, and reduces coolant expense for FMC.
However, it doesn't mean it's the best coolant for your diesel engine and cooling system, regardless of how popular it is or how hard it is pushed here at TDS. /ubbthreads/images/graemlins/crazy.gif
The "Gold" will contain silicates. These silicates "wear out" quickly, and eventually distract from the other inhibitor properties of the coolant. Thus the shorter operating life and shelf life when compared to other extended life coolants. These silicates also form drop-out, which is an abrasive contamination. This is known to be a contributing culprit to the many water pump failures we see here at TDS.
The Gold will contain a less robust inhibitor package for heavy duty diesel engines. You won't find it meeting the heavy duty diesel specs of other V-8 diesel makers like CAT, Mack, Detroit, or Cummins. Even International does not recommend it in the T444E (Powerstroke). They factory filled with the red Texaco ELC. And don't forget that like all ELC's, the "Gold" won't meet your ESE-M97B44-A coolant spec.
So if you're looking for advantages, look for a coolant that is silicate, phosphate, and borate-free. No drop out contamination worries. Your cooling system and water pump will thank you. These coolants will remain maintenance-free for 300K miles, not just 50K or 100K like the Gold. They will have a more robust inhibitor package specifically designed for heavy duty diesel engines. They'll meet the specs of the big guys, and agree with what International uses in this engine.
I've listed many of the popular brands over and over, but the mods never post them or include them in the coolant flush procedures. /ubbthreads/images/graemlins/rolleyes.gif
