    Die Flüssigkeit scheint zu funktionieren, auch nach über 4 Wochen kein Wasserverlust und keine Ablagerungen von Öl/Kühlmittelschaum im Öl-Einfüllstutzendeckel mehr. Kühlmittelverlust war ca. 1/4 Liter Kühlmittel auf 200 Kilometer, es war also ein kleineres Leck.

    Worked to a degree, still loosing water into the block after treatment but much reduced. Cylinder head gaskets now available so I will swap it out.

    Fast delivery and great price, looks like it's done the job as well. It's fixed the leaking until I get a newer car in 6 months. Thank you very much. Great seller
