good product

This stuff works great! sealed the blown head gasket on a Kia Rio

Impressed. No Problems

I used this on my 2004 Jeep Grand Cherokee 4.7 liter, worked as advertised, read the directions 3 or 10 times, follow the directions and it will work for coolant leaking into the exhaust system.

Excelente producto y buen precio

Received as described . It works for small leak ( cylinder Head )

I cant begin to explain how helpful this product is in plugging leaks temporarily til the leak can be repaired!

21 year truck overheating and blowing antifreeze back into the reservoir either this stuff was going to work or head to the bone yard , happy to say still driving truck and running fine. Just amazed how good it works that was a month or more ago

Great product. It stopped a mild head gasket leak, and after a couple of days- eliminated the mild white smoke coming out my tailpipe. The key is strictly following the directions, and wait a few days for it completely work. If you properly diagnose the problem, and follow the directions without deviating- it works great! Highly recommended!

Help with the problem we had!

Good

Seemed to of worked

Okay so I got this product from a local Walmart. This stuff works magic I know many mechanics that recommend this specific kind. So one down side tho. I used it on my 2006 Honda Accord 4-banger. So this car was overheated and melted the head gasket. Unfortunately I did not realize this because I just replaced the coils and i drove it till it blew up. According to my iodb2 scanner it blew a hole in all but ones cylinders head gasket. I did not want to pay 1100 dollars or have a full day repair I used this stuff it worked a miracle. Took 15 minutes repaired it almost instantly after the thermostat opened. Sadly the sealant got in the oil and messed with some vtec sensors. Still don't have a head gasket problem. I gave this a good review because it works miracles for a head gasket just don't let it get in oil!!!

Had a radiator blow while driving for a move. It turned out that my head gasket had a small leak and combustion gases were over-pressurizing the coolant system. After replacing the radiator, I put some of this in and followed the directions. No more bubbles in the coolant. It has been about 500 miles of driving now and the seal is still holding.

Back in September of 2019, my 2003 Infiniti G35 sedan's radiator finally burst spilling and splattering hot coolant all over the ground. Replaced the radiator with a new one and also changed the thermostat. The car's temperature gauge kept going beyond the half-way point after a few miles of driving before pulling over to the shoulder. The diagnosis was ultimately a head gasket issue, which would involve quite a bit of money and time without the vehicle. So, decided to give Bar's Leaks 1111 Block Seal Permanent Head Gasket Fix 24 oz. a try, and it is now August 2020, and still no overheating issues nor white smoke from the tailpipe. This is a real review for those doubters, and I'm not getting paid for this review and is unsolicited.
