BlueDevil Automotive Head Gasket Sealer Pour-N-Go

Blue Devil Head Gasket repair is the real deal! Super easy to use, worked instantly! seems expensive at the $ 30.00 I paid for the small bottle I bought but compared to the $2,000.00-$3,000.00 to have it fixed in the garage not to mention the wait time of 2-3 weeks before they could even get to it, I was able to drive my car no more than 30 minutes after applying Blue Devil!

I had some bad head gasket leaks, oil in the coolant, coolant loss, oil dripping on exhaust manifold, rough idle, stalling. Blue Devil Head Gasket Sealer has cleared up most of the problem. But it took a little bit of driving each day for several days. Anyway, no more oil in coolant, no more coolant loss. Rough idle improved but not entirely gone. Probably that has another cause other than leaking head gasket; still I'm hoping it will get better.

Price at Walmart was the cheapest I found at any retail seller including EBay. This is the highest rated head gasket sealer . Many videos on the this product on YouTube

After finding out I had a small head gasket leak in my 2017 Chrysler Pacifica I tried K-seal and it did not work. I had to flush the entire system properly and then used the blue devil pour and go and follow the exact directions. This is important! Short answer is it works!!!!!

This product really works so simple to use. My heater core had a leak and kept putting steam on the windshield after following the instructions, added to the truck water system, the problem has been resolved for now, and I know this is just a temporary fix, but still really helps, and saves money in the winter, cause I need heat. If I need to redo the process again I will, but its been 1 month and holding. The cost for heater core replacement $3200, this product $45, if I need it again, still worth it, it would take 75 times using this to equal the replacement cost, so, each and every other month, I will reapply the product, and roll with it. Great product for my vehicle.

Worked well, I don't know how long it will last but it will get me by until I can make proper repairs

The product stopped my leaking head gasket! However, it also stopped up my heater core! The company recommends preflushing anything that could accidentally get clogged. I'm not sure if that would have kept my heater core from getting clogged.? Thankfully, I was able to forcefully flush my heater core and save it! The product looks like little Styrofoam ball pieces after it came out of heater core! I'm thankful my radiator was newer and didn't suffer blockage! Great product! Use with caution!!

Followed instructions on the bottle and now my whole cooling system is damaged and needs either hard flush or radiator replacement and possibly head gasket replacement

poorly packaged... product leaked out during FedEx shipping

didn't fix my head gasket
