I had a leak in the radiator of my car and I used your product and today saved a lot of money. Before that, I have to buy a gallon of coolant every week and now I don't buy coolant any more, I forgot when was the last time I had to buy it. After that, I bought your products for engine and transmission and used them. My old car is working quiet and it is saving gas, I don't know the exact quantity but I know that I am saving money in gas. I am very happy with your Cooling System Repair (part 1150) blue and black product in the clear double sided bottle. You guys are the best, thanks again.

I had a substantial drip coming from the water pump. Your product was able to seal it after a 20 drive. Thank you for a great product.

Let me preface by saying I don't know much about cars. I only know that I've had horrible luck with them. I've done a lot of work and maintenance on my Ford Escape 2005. The first time it was overheating, was because the fans were broken. After I got them replaced, the car ran good until it got a leak somewhere in the reservoir/tubes to the radiator. For months I had to keep dumping coolant/water into the reservoir EVERY SINGLE TIME I needed to get to work or even just go down a few blocks cause it would start leaking badly after just a few minutes of putting it in

I tried for weeks to find the leak but could never find it. I was skeptical that the Cooling System Repair (1150) was going to work, but I tried it at the recommendation of a friend. I am happy to say that it definitely works. In my case my car is still overheating but at least a lot less faster, and I haven't had to add any coolant or water for a week now. Just remember to SHAKE WELL!
