Coolant expansion tank question
Searched around but I couldn't find a clear answer.
Does coolant flow freely in and out of the coolant expansion tank when the engine is running? or is it a true auxiliary tank that the system only draws from when it needs more fluid?

You won't see any movement, like flow of liquid in the reservoir. Its only purpose is to supplied liquid when needed , allow expansion of fluid and air when Higher temperature is reach but it is good to know this reservoir is under pressure like the rest of the coolant system when heat builds up ...I think it is up to 14 or 15 psi.

So if I put an additive into the tank it will not free mix with the coolant in the whole system?
Is there another place you can get direct access to the system?

I was thinking about adding some Amsoil Coolant Boost. I added some to my tow vehicle today and it worked surprising well. It brought the normal running temp down about 15 degrees.
But if I can't add it directly into the Turbo's system I don't think I will do it.
What do you think?

Sorry I cannot help you with this one since I never added anything in the coolant system or into the fuel system. But , of course, be careful with any additive....

The long-life coolants (yellow or red) used in modern engines creates a special corrosion resistant coating in the coolant passages. Adding the old green coolant permanently alters this coating. You can never go back once you disrupt it. Flush till you flood the neighborhood, it's done.
I looked at the Amsoil product's webpage and it doesn't state that it's safe to use in extended-interval coolants so I'll assume it isn't. If it was, they'd state that it's safe, and increase their business.
It may decrease temperatures if that's the ONLY goal. Corrosion resistance isn't so important in "race" engines for which this product is marketed.
