Double amount keep heater off works
I doubled the recommended amount in a V6 engine. Drove it high in the RP m's with the heater off. Allow to cool overnight in my case, it was a couple of days and did initially it didn't seem I wasn't allowed to cool long enough. Although after sitting for a couple of days, it's still completely prior to us in the case, ill division was losing a gallon of coolant every hour after continuous highway driving.

HA FUNZIONATO EGREGIAMENTE
Ho prima messo a livello l'acqua nella vaschetta a motore freddo, ho tolto la quantità d'aqua dalla vaschetta pari al prodotto, ho versato il prodotto nella vaschetta , ho avviato il motore METTENTO LA STUFA A CIRLCOLO ARIA CALDA , ho fatto riscaldare da fermo il motore fino a 80 gradi poi ho circolato per 3/4 km . ho spento e fatto raffreddare 5/6 ore. dopo di che ho usato la vettura regolarmente. IL PRODOTTO HA FUNZIONATO. La vettura è una Fiat stilo SW 140cv Multijet con 450.000 aveva soffiatura alla testata che mi consumava circa 150ml di acqua ogni 100 km (un bel bichiere di acqua) cacciando fumo bianco dalla marmitta. Ora dope Tre giorni ho percorso circa 560 km NON CACCIA FUMO BIANCO NE CONSUMA PIU ACQUA: al momento va benissimo non so quanto duri . comunque ho rimandato la rottamazione!!!

Signed and Sealed
Used this on my 2005 Camry for a temporary fix on what I think is a head gasket or heater core issue. Made my car run better and will run through for 1000kms and reflush. Not a permanent fix. However will do until I decide if I want to buy another car. Great product and would highly recommend 5 stars
