I honestly do not take any delight in giving a bad rating on any product.., but as long as we are relating to the subject of honesty, this product nearly destroyed my cars engine! I only had a minute leak, and even though I followed the the directions perfectly it clogged up the system so bad my cars engine almost exploded! I would never use this product again, nor would I recommend it. I do recommend K-Seal as I believe it is the best product on the market right now, even better than the over-rated and over priced Steel Seal. As I stated above I don't like to give bad ratings, and sometimes the truth hurts.., sorry, just being honest. Thank You.

Just not this particular size of bottle even though it was recommend for 4-6cyl cars it only work about 10mins after driving it when done following instructions. I have used the more expensive bottle which is twice the size and has a yellow label instead of white it worked excellent for about a month then it had a thermostat housing leak and my husband over heated it and blew the seal again I was just hoping I could save sum money and get the same results but you get what u pay for so get the the more expensive stuff.

This product has claimed to work on leaking freeze plug. It does not. It says it works as a blocking agent once it hits the air through the leak from hot to cold. It did no such thing. I basicly sat there and poured 30+ dollars of a blue liquid into my radiator and watched come right back out of the leaking freeze plug. Absolute garbage. Dont use on freeze plug. As to weather or not it works on head gasket i dont know. But for blue devil to he all over the web claiming to work on leaking freeze plug is a sham.

Seems to have work but I flushed my system 4 times with water then with chemical flush then water again then the blue devil in water. This product takes a full day to do properly. Don’t rush and it will do the trick.
