Highly recommended

Great product! It saved my radiator actually I made it through the heat of the summer. It took a second bottle of it before it worked completely but my truck had a sizable leak so it was still better than replacing the radiator. I am very satisfied and suggest using it because convenience and value. It saved me a lot of money and time. Thank you

Best product for engine leak

Had a very small leak (nothing visible) in a ten year old van with well over 100K. Only used half the container and no more leak. Dont expect this to fix a visible leak like a hose or radiator.

just be aware. this product does freeze. we were in a weather pattern where we'd have several really warm days followed by several really cold etc. and i was unaware that this product would freeze like it did. not good for your vehicle to say the least! but its seems to have helped none the less.
