1109 Block Seal Liquid Copper Intake and Radiato

OMG thank you for this wonderful product!! I used it in my old skid steer which was leaking a lot and overheating. Replacing the radiator does not seem to be an option- it’s above my ability and can’t find a mechanic to work on it. I had tried other radiator seal products with unsustainable results. As a last ditch effort I ordered this Bar’s copper block seal and it WORKS!!!! It has been several months and is still working, I am so very happy. The cost is a bit higher than the other products that did not work. For any future problems I won’t waste my money on cheaper products, this product is totally worth the extra few dollars. In the end it has literally saved me hundreds of dollars.

No more minor leaks . Water pump no more noise.

I had a minor coolant leak coming out the passenger rear side of my block, about several drops after engine shutdown, small head gasket leak. I added a bottle of this stuff and it seemed to have stop the leak...been several months so far. So far, so good. 1997 Ford F150 4.6 V8 with 140k miles. Engine has never been apart.

Did what it said and stopped a block leak in a 2007 Mazda 3. I only needed to use half the container, so I still have some left for another leak down the line. Not much else to say.

Bars a is always a good product . Just used as stock this round.
