Review on 🚀 Enhanced Performance Radiator Relief Coolant Booster for Water Cooled Engines, 16 oz. by Jordan Rini

Unfortunately that didn't work. I had high expectations after reading the reviews. I have a neat 12 Grand Sport Corvette and I don't race, but it's a daily drive. The engine temperature remains at 85°+ as before the additive (205°-220°). I haven't seen any difference in 2 months. Filled up according to instructions. Money down the drain and of course not back.
