DexCool Maligned?

In this litigious society, if DexCool was even 1% as bad as its detractors claim, GM and Texaco would both be out of business by now! GM has used this stuff for a generation now. '
Where Dexcool fails is in iron-block engines that suck air into their cooling systems - older design engines with unpresurized overflow tanks which can suck air in past the radiator cap. In those cases, the oxygen in combination with the coolant chemistry produces rust, which clogs everything.
But Saabs have had full pressure overflow tanks since at least the days of the V-4. There's no way air gets sucked back int othe radiator past the overflow. Most of today's engines are that way as well.
As for G06, it's organic acid based chemistry is essentially the same as what's used in Dexcool, but the sebacic acid chemistry doesn't last as long, and to it they add seal-abrading silicate.
I used Dexcool.
