Great product!

This stopped a very minor head gasket leak in an older audi within 5 minutes. So far it has been a week and not one drop of lost coolant, no sign of overheating, and zero bubbles in the coolant tank. I cautiously used just a half bottle for a four cylinder as others have recommended and it has worked properly. The coolant has turned darker and I will leave it on over the course of the summer. When the fall hits, I will completely flush the system, which is easy to do, and refill with the proper coolant for the vehicle. I did turn the heat on high to make sure that the coolant was flowing properly through the heater core. Even though it is summer, I run the heater on high in the mornings for a few minutes to make sure that it is still blowing hot air, and it is. Once the car gets warm, I switch over to AC. This product will definitely stop a MINOR head gasket leak very quickly, and possibly permanently. I went from using a gallon of coolant per week to none in the last week. For an older vehicle, it is a very inexpensive repair and definitely worth a shot!Read full review...

Did not work for me.

I used this product with a lot of positive spectations, but it did not work. I used it trying to fix a headgasket on my 1995 Land Rover Discovery, the pressure in the system continues, so I will have to change the headgasket on my engine.Read full review...

Did not make it worst but didn't fix the problem either

Did not fix my leaky head gasket problem in my 2006 Scion tc
After a few hundred miles this just got spit out of the overflow tank reservoir and I still ended up losing coolant which I have to refill once a week.Read full review...

I was replenishing coolant daily until I used Solv-Tec K-Seal

I was a little reluctant to purchase this after reading some reviews but the product worked as per manufacturer’s claims.

Works on small liquid cooled engines too.

I was loosing antifreeze on a small liquid cooled engine and could not find the leak. Added 1/2 of the container and the problem is solved.
