Yes, keep in mind you want antifreeze for an open loop cooling system, you don't need coolant. Just trying to keep the liquid inside from freezing.
Propylene glycol is the non-toxic potable water system antifreeze I prefer, ethylene glycol is a coolant and is toxic although the base chemical is also biodegradable. We don't need to use ethylene glycol IMO, propylene glycol is sufficient.
Put this stuff in straight, don't try to mix it with water, it's already pre-diluted.
If it has salt in it as an ingredient it's gonna be corrosive, can't imagine why any reputable company would put salt in any antifreeze. So, you could taste a drop to see if it's salty, it should taste sweet like the sweetener in white wine.
Food Grade propylene glycol is used in many processed foods, and as a laxative.
