Also, I've heard that Dex-Cool should *not* be used in any vehicle with a brass radiator. (I don't think any VWs came from the factory that way, but I've seen aftermarket brass rads for them.) I've heard two different stories on this -- that the Dex-Cool actually corrodes the solder joints, or that it simply doesn't protect them from corrosion. Either way, bad news. |
