Engine Coolant

IME the blue stuff starts to go brown with rust once its no longer effective, not clear
Agreed, but the Parflu stuff I use looses its blue long long before it becomes ineffective.

I was talking about cooling systems that work? Or do I have to place caveats on every post I make to mitigate cars that aren't maintained properly?
I regularly get picked up on for not including every single little rare exception to a piece of information, why do you deserve a break? :p
