    Really seems to work.

    I have a 2000 Ford explorer. Developed a bad head gasket and was literally spewing water off the front of the motor. I parked the vehicle for 6 months as I didn't have the time or money to get it repaired. I came across this product so I thought I'd give it a try, and wow!!!! Two or three minutes after adding this product the spewing completely stopped. I couldn't hardly believe it. So far so good.... Two thumbs up.

    A Product that WORKS!

    Not sure where or why the coolant system in the MB E320s develop leaks but they do! A bottle or two of K-seal seems to take care of the problem. Add the K-seal, add coolant and water at a 50/50 ratio and then drive the vehicle for twenty miles or so and the K-seal does its job!

    There are not many things you can rely on

    However Solv-Tec K-Seal you can rely on to do it's job. With in Ten Minutes it got my leak fixed and it is still leak free. The price was nice not too expensive and took delivery with in a week. You just can't beat it and at the price you've got to try it.

    Great product. Worked as advertised

    I've been chasing a very small leak for months now and could not locate it. I used one bottle of K-Seal and no more leaks. I was skeptical at first, but after a few weeks, I have not lost an ounce of fluid. Awesome product; would definitely buy again.
