What is the difference between pink and green anti-freeze? I have 3208 T/As...

The color.
I know that answer may look stupid but...

Don't mind me but this is not quite true.Green antifreeze contains Glycol and cannot be used for winterizing as you cannot dump it into the water when starting your engine. Green should only be used in your fresh water cooling (also orange). Pink antifreeze is used for raw water systems and potable water systems.
Unless I'm missing something with the original post this is very common knowledge.

Folks using "drinkable " AF to winterize the boats fresh water system will do best by filling the lines and leaving them full.
If you simply flush with the pink goo some will be left in lines and devices , where it can go solid.
This means in the spring it may take a week and multiple flushes to soften the dried out AF and have clear water .

You stole my answer.
Very glad to meet another great mind lol

Continuing with my ignorance theme...
Why can’t propylene glycol be used in an engines cooling system?
Heat resistance.
Ethylene glycol is more resistant to heat (higher boiling temperature). Propylene glycol is decomposing when exposed to oxygen in air and heat and become corrosive (acidic).
Theoretically anything can be used for cooling engine, the most basic one is simple water. Difference is efficiency, durability and protection.

Propylene Glycol is the vapor you see from a person with an "E-cigarette". It is 80-90% of the ingredients they are "vaping" How smart is that?Lou is correct. Ethylene glycol which is dyed green, yellow or orange is used in engine cooling systems and is very toxic. Dogs have been known to die from lapping up a puddle of it.
Propylene glycol which is usually dyed pink is used for winterizing water systems and is reasonably safe to drink (a little).

I have a small leak on the port engine and I am trying to hunt it down. Sitting static, no leak. Running where the system is pressurized I get some drops below the engine on the outside of the port engine. Hard to get too, but I will find it.
