Review on 🔋 Phosphate Free Zerex G05 50/50 Antifreeze/Coolant 1 Gallon - Ready-to-Use and Prediluted by Mike Hamelin

I bought this system cleaner/coolant flusher for my 2011 Corvette GS. After a fairly complex physical cleaning and flushing of the system, this material came back exactly as the factory material. Same color and service rating, including factory recommendations. After a year; No problem. The engine runs as intended and stays cool. Serious damage can occur on these vehicles if the cooling system is not kept clean or if an unapproved coolant is used. I used to think about buying a Corvette until I heard a horror story about coolant getting into the transmission because the store drained the radiator and filled it with cheap replacement coolant. The acid has eaten the aluminum in the heatsink!
