The biodegradable orange stuff is OK. It is phosphate free. I've been
running it 5 years and so far no problem. But, I change the coolant
every 24 months without fail. I also add a bottle of Redline WaterWetter
to the coolant when I change it.

The orange coolant loses it protective qualities for aluminum over time
and becomes corrosive. Change it often enough that the coolant is not
allowed to move into the no protection/corrosion zone. Also, be sure to
maintain the coolant concentration at the 50/50 level. 50% Water/ 50%
Coolant. Better to use distilled water for coolant mix as well.
