1989 Bronco 2 with some kind of water jacked leak into the oil... basically noted light-colored froth on bottom of oil fill cap and the coolant reservoir would drop over a week... Well, I put this in WITH the thermostat in place and it seemed to work well so far!, NO further coolant loss in overflow reservoir and temp stabilized.... So far, so good after about 1mo.

Product seems good, hole remains

Reviewed in the United States on August 21, 2010

The product is easy to use, and the instructions are simple. I'm pretty sure it would work too- I can see the substance gumming up on the surface of the water in my radiator.

Unfortunately, it did not work.

However, take my experience with a grain of salt- the hole in my radiator is at the very top, and sees very little water. I'm also running pure water mixed with water wetter, rather than coolant. Additionally, the hole was the size of a quarter, so I filled it with JB-Qwik. This reduced the leak to a pinhole hiding somewhere. I don't know if Perm-O-Seal is supposed to work alongside JB-Qwik though.

-2 stars for not working for me, but I'm pretty sure it would work on a normal radiator leak.

My car was overheating for a few weeks without seeing were the leak was coming from. My mechanic check out my car and said it could be so to worn head gaskets and he told me to try this product. I tried it and a week later, my car stop overheating. This product saved me thousands of dollars of costly repairs.

Don't follow directions. Does not work as says.

Didn't work Can't be used if there is fluid in the RAD. The JB will float to the to and even with the engine running as you fill it up it rises to the to of the RAD.

had a leak that was giving me fits...tried regular jb weld and slowed it down but did not stop it...so I gave this a try without any expectation for success....after a couple of days in the system I noticed I did not have a puddle under the vehicle....I do not know how long this will last but it did stop the leak....
