Our coolant seal treatment inhibits the formation of rust and scale, keeps the system clean, neutralizes pH imbalance, controls electrolysis and lubricates and seals internal, external and coolant-to-oil leaks. These pro-grade tablets fully dissolve in minutes and are harmless to ALL plastic, metals, aluminum, hoses and connections. It’s the strongest and most innovative treatment we make.


Install directly into radiator per dosage chart on package. If vehicle does not have a regular radiator cap, remove top hose where it connects to the top of radiator and install tablets in hose. Tablets may be crumbled or pre-dissolved in warm water for easier application.

Great stuff

This stuff works really great.

 by Ernie - Newport News, VA

I used your cooling system tablets to fix several large leaks in my moms 2005 Dodge Grand Caravan. The plastic radiator tank seals on the sides of her 2 year old replacement radiator were already leaking and wasn't covered under warranty. A $200 new radiator was too expensive for her to buy at the time. Within 3 days, the leak had completely stopped. Not even a small drip. I also used this in my Ford Ranger to stop some seeping from the water outlet gasket that I've replaced 4 times due to leaking. Completely stopped the leak within an hour. It's also a great bonus that the tablets correct the antifreeze PH, stops corrosion and lubricates the water pump bearings and seals. Bars Leaks cooling system treatment is an amazing product and I will recommend it to everyone. Thank You for such a great American made product!
