interesting coolant stuff

[rfkellner@snet.net (Rick Kellner)]

The site below has some extensive discussion on coolant, anti freeze and
corrosion inhibitors.  It also discusses the mix used in VW and who
makes it.  Here is a quote about 1/4 of the way down the text.=20

      Info from Marketing Service:
        BASF makes a 'generic' brand of GUARANTEED Phosphate Free
        coolant called ZEREX EXTREME 450.  It has been approved by
        VW, BMW, MB, Audi, Saab, and Volvo.  It is also GUARANTEED for
        four (4) years and 50,000 miles.  They said you CANNOT mix this
        with any other coolant; you must flush the system and fill with
        the new coolant/water mix."
