Re: coolant

Huw;

    Sounds like the coolant you were using was degrading the metal
components in your cooling system.
    I just drained 8 year old, 258k km Audi coolant from my '91 200q. The
coolant looked brand new and the cooling passages ( those I could see with
the water pump out) were spotless.
    The 150k km Audi coolant I drained from my old '86 5kcstq to replace the
heater core was the same and the internal passages in the heater core were
also spotless.
    The Audi coolant is expensive, but I think it's worth it in the long run
to avoid internal corrosion.
