B7100HST-D Cooling system: Should I use some flushing product?

[TerryKing]

Hi Everyone,
I did some searching.. Would appreciate your experience and suggestions.

NO cooling problem, but I am about to add a lower radiator hose heater and drain the system / refill 50% antifreeze. New hoses..

Should I run a flush cycle on the system with some "radiator flush" product while I can? What is the "FUR" that is mentioned in some of the manuals? Example:
-----------
When cleaning the water cooling system, the Kubota
Fur Inhibitor No . 20 is recommended to effectively
wash away the built-up fur .
-----------

Or if it ain't broke don't add MouseMilk?? What do you think?

Radiator externally cleaned with the right-angle blow gun nozzle someone posted about.(Phot0)

Vise crimp and hacksaw

Thanks!

NO, it's a thermosiphon system ( no water pump) so it will not circulate and clean anything.
A good water flush is all you should do with that system.
