Nalcool 2000 prevents high percentage ethylene glycol from getting gummy. The oversize radiator is shiny brass inside. One treatment, 1998 and the coolant will last damned near forever. I did a boil test on the thermostat and the engine iron looked like brand new (2016).
I remember one of the last things I did when packing the containers was to fill carboys with 48 cent per gallon Wal-Mart distilled water. SanMar could care less what the 35' containers weighed. Every car trip means ten gallons of distilled water. Mexican Customs opened one gallon and poured some into a palm and smelled it. I told them it was for my BiPAP machine. They abandoned curiosity in under 3 seconds.
Distilled water costs like sin down here. They call it liquido Para Baterias. Often costs a dollar and a half per pint.
I found the old DOW blue antifreeze the least offensive as far as garbage additives. With Nalcool 2000 it is quite a coolant.
A non issue with me. I have no desire to cross the border. Everything I want or need is stateside.
Far as coagulating coolant, My tractors all get changed bi yearly. Only time I've heard of that is when someone mixes red extended life with green gycol.
None of mine have alloy heat exchangers. All are aluminum with plastic top and bottom tanks.
