Review on Prestone AS661 Engine Block Stop Leak with Kevlar: Powerful 16.5 fl. oz. Solution for Effective Leak Repair by Dustin Ramsey

Finally! A coolant leak remedy that really works! Over the years and on many engines I have tried every product that has ever been offered to stop minor leaks anywhere in the cooling system (certainly not in the water pump drains). All were also recognized ... crap, which did nothing to solve the problem. Nothing has worked before and no one I know has ever patched a hole/crack with other products. Guys I'm here to tell you guys I performed the Happy Miner's Dance after realizing that Preston's Triple Seal actually did what they said they did! Glory Hallelujah. I never thought I would live to see this day. Use it. IT WORKS OUT!
