I AM AMAZED
I couldn't see where the water leak was coming from but it was a consistent leak. I decided to give this Hapco Cooling System Sealer a try after trying many other brands from the auto parts store. It took a lot longer than the product instructions suggested for the leak to completely stop. Initially, the product slowed the leak but after driving for a while, it completely stop. I would highly recommend this product for cooling system leaks.
