Review on 🌡️ BG Universal Cooling System Sealer: Efficient Solution for Overheating Engines by Jermaine Munajj

I have a small leak in the plug and what appears to be a small leak in the heater core. This product has no sealed. General Motors uses crushed walnut shells as a leak stop agent (AC Delco tablets). I suspect BG uses the same product, puts it in a solution and labels it. I don't have any proof, but the fact that the BG product is "organic" and brown as a pill pushes me in that direction. All of this to say that we know leak prevention products suck and I got what I expected.
