Review on 🔒 Authentic GM Fluid 12378255 Cooling Seal Tablets - 4 Grams, Pack of 5: Genuine Quality for Your Cooling System! by Pranav Osman

Replaced the water pump on my Corvette 95 only to notice a small drip on the bottom of my radiator as the system was flushed and there was new coolant ( green) I tried 3 of them in the upper radiator hose, warmed up the car until the radiator fans started up at 227 degrees, running time 15 minutes, the next morning there was still a small drop of coolant on the floor, let it cool down for the night, the next day was the weather good, so drove at 25 minutes speed on the Autobahn, checked the next morning, the leak was tight, so far satisfied, time will tell when the outside temperatures will be in the 80-90s, hope for the best ,,,
