    ACDelco Cooling System Seal Tabs are specially designed to prevent a minor cooling system leak from turning into a major disaster. These small four Gram tablets are designed to dissolve into your cooling system sealing and preventing small radiator leaks and coolant loss due to casting porosity in engine components. The non-toxic organic formula also controls electrolysis, neutralizes pH imbalances, lubricates internal cooling system components, and inhibits the formation of rust and scale.


    • Professional-Strength formula for a permanent seal against microscopic leaks and porosity
    • Harmless to all plastic, metal, aluminum and hoses in the cooling system
    • Works with water and all types of antifreeze

    10-108 - ACDelco Cooling System Sealant Tablets is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from These work, plugged up my leaky freeze plug Had a leaky freeze plug, the one right under the motor mount too. Brand new motor. Engine builder said to try these but to buy the AC Delco brand. I also used water only in the system, no antifreeze as I think water only helps these tablets do their thing. A few heat cycles and 3 tablets did the trick, no more leaky freeze plug. Mine was dripping pretty good too, no more. I doubt these will fix a "pouring" leak but if you have a dripping type leak you should give these a try first. Thought I was gonna have to pull motor to fix.. whew!
