[s-cars] antifreeze/coolant color

[Gabriel Caldwell]

I would always err on the side of caution.  You have no clue what's in
the car and some antifreezes can react together creating sludge.  Flush
it and fill it with what was in there before.  If it turns out that the
green/yellow (?) stuff was OK then you are out what $20?  That's way
better than clogged up cooling passages IMHO.

Well, looks like a debate is inevitable.   :)

My mechanic, whom many of you have utilized in various ways, believes 
that the green VAG stuff is less corrosive than the pink VAG stuff 
(which came with my S6).  I can't comment on blue stuff.

In any case, if Stefan's mechanic is even remotely competent, he didn't 
put in anything inimical to the engine.  Whether it is optimal is 
another question.  So, flushing it before communicating with the 
mechanic strikes me as an action figuratively lying between overkill and

shooting oneself in the foot.
