Had a cracked radiator where I needed coolant damn near every 40~ish miles. So it was a pretty decent leak.No money to fix it properly, so I grabbed this. It's held strong for the last 2 months with no issues so far of gunking up my system.I drive a beat up '02 Honda Civic. If it wasn't a beater of a car, I'd be too reluctant to try it. But, glad to say it does work.

4.0 out of 5 stars Just follow directions. If you need more put a small amount in.

It may take more than one bottle. Also Its better if you don't put antifreeze if AFTER the Bars If it needs antifreeze, put in before. It is pretty good. And follow directions about letting your car run for a short time. Its all on the bottle. It works better than the "Stop Leak" by Bars.

Worked great for me. I had a small leak in my radiator and this product worked. Really easy to use and fast acting.

Had a small leak and couldn't find it. This fixed it.

3.0 out of 5 stars I was hesitant

I decided not to use it after conducting further investigations. Some people said it clogs up their coolant system causing more damage and money down the line. I decided to find the reason for the leak and was glad I did because one of my flanges was made out of plastic and it had a crack so I replaced that with metal.

5.0 out of 5 stars Good

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.

Didn't work for me.

Had a small leak around the joint on radiator and this unfortunately didn't do the trick. Neither did anything else we tried. I guess it depends where the leak is. It did however make everything glittery.
