Here is my DIY kit to reverse flush and get nearly all of the old coolant out
http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/24272597/gotomsg/24272676.cfm#24272676Back on DeathCool...some of the OATs and HOATs employ 2-Ethylhexanoic acid as
the organic acid to prepare (etch) metal surfaces inside the cooling system for plating
a corrosion protective coating
That acid is also a plasticizer...meaning it melts or softens plastic. If there
is any plastic in any of the coolant system gaskets (this included the head
gasket)...it will soften it to then potentially have it leak...
So the question...is all of the 2-Ethylhexanoic acid consumed during
the etching process that turns it into a metal oxide or is there any
left floating around looking for something to etch? The what about
the metal oxide floating around in the cooling system? Will it stay
as is?
Nope...if O2 gets in there...they will then combine and or react with that O2
