Hat einwandfrei funktioniert
Hab es beim Audi Cabriolet 2,6 von 1994 angewendet, da die rechte Kopfdichtung einen Schaden hatte (Kühlmittel gelang in den Brennraum von Zylinder 3). Es hat einwandfrei funktioniert. Hab 4 Monate danach erst die Kopfdichtungen erneuert. Bis dahin lief der Motor wunderbar ohne weiteren Kühlmittelverbrauch.

Works
This stuff does work, how long for I don't know time will tell. Bought for my partners car as she was losing water somewhere, I put this in following the ideal procedure water out, engine flush, and adding back into the system, allowing to circulate round the engine. She's not lost any coolant upto now and its been over a week. Was very sceptical being a 40 quid bottle over what could be an expensive repair job but upto now it seems to have done what it needs to.

E' come tirare una monetina...
Non ha funzionato su una Punto 188 1.2 8v del 2000: la temperatura dell'acqua sale ed entrano gas combusti nel circuito del refrigerante, perche' la guarnizione di testa e' rotta. Pur avendo drenato il vecchio refrigerante e usato solo acqua e SteelSeal e pur togliendo il termostato per far circolare subito il liquido, non ho ottenuto la sigillatura. Peccato perche' chiedono 450 euro per firare la guarnizione di testa.
