    SAAB's antifreeze in no different than anything else. Its either
    Propylene
    Glycol (standard stuff) Dexcool, or the enviro stuff. Have a look at the
    label and figure out what's in it.
     

    Not quite true. Silicates Borates and Phosphates are common additives.
    They all settle out and can block cooling passages. That is one reason
    for the for the coolant change. Any coolant containing also has a shelf
    like. When was the last time you saw a "sell by" date on a jug of
    antifreeze? How long was that cheep antifreeze on the shelf? How long
    before it settles or gels? Silicates also bond to the ceramic seal and
    increase ware a few hundred percent.
    As for protecting aluminum and not protecting brass,please point me to
    your references

    Propylene Glycol is a food additive. The standard stuff is Ethylene
    Glycol.

    For a quick check of corrosion resistance of your antifreeze try sticking
    the probes of a high impedance volt meter, one in the coolant not
    touching anything else and one on the engine block, you might be
    surprised at the potential.
