  • How does Bar’s Leaks Professional DiFM Cooling System Treatment 5 gram tablets stop a leak?

    It will seal external, internal and coolant to oil leaks. Once installed, the Bar’s Leaks particles shrink up to 15 percent. On an external leak, the tiny particles flow to the point of the leak. They then collect at the outside of the seepage and build inward. Internal leaks, the Bars Leaks particles will burn when subjected to the 5000°F heat of the combustion chamber to seal minor head gasket seepage and small cracks. On coolant to oil leaks, where coolant can seep into the crankcase contaminating the oil, the tiny Bar’s Leaks particles will seal the pores in cast iron and aluminum preventing this seepage.

    No, it will not damage the cooling system. It is harmless to ALL plastic metals, aluminum, hoses and connections. In addition, it is non-toxic. Tablets fully dissolve in minutes.

  • Will Bar’s Leaks plug my heater core?

    No, the tiny particles will pass through a 24-gauge mesh screen (this is like a screen door mesh) which is the spec for the BIG 3 car/truck manufacturers. They say that any product installed in the cooling system must pass through this screen. Bar’s Leaks is the only stop leak to pass this test and to be approved by the vehicle manufacturers. Note: If using Bar’s Leaks to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core.

  • “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!”
