    Got a leak? this will plug it quickly well worth the money

    This product works and does not take much time to stop engine coolant leaks.

    Product Works!

    I was as skeptical just from the looking of these tablets. The car is a 96 Buick Skylark, transverse engine, with the leak coming out just below the crankshaft pully. This leak was dripping at a rate that would drain a gallon in approx. 30 minutes. We put two tablets in, drove 20 miles, let is sit for 1 1/2 hours. Started up the car and the leak was gone. 3 weeks later and still no problems.

    Great Product!!

    Got the GM sealant tablets. Read all directions. My vehicle does not have a radiator cap. Crushed tablets, dissolved them in warm water and poured in coolant overflow tank. Drove around for forty minutes. LEAK GONE. Great product!!

    No Coolent Leaks

    Restored 1987 Buick Grand National not leaking Coolent. I put the tabs in a shop rag and gave them a couple of whacks with a dead blow hammer and installed the results in my lower radiator hose; the concept came from the Buick Grand National forum with the idea being that the tabs would go through the engine block before they went through the radiator - no leaks.
