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!

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.

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

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.

I love shopping at Walmart and I love blue ***** at work. Great had my truck running back in order in no time

Fix the problem, made another, but not really sure about if it made another. I have been dumping in head gasket sealer of different varieties so that might've caused the water pump to don't put in your reservoir whatever you do radiator only or even your hole connected to your reservoir, maybe too slow poorget it good in there before you start the engine then cycle engine and let it idle for a long time I run the heater we will see small and crack, but the crack gets bigger. Eventually, the head gasket seal will give away.

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!!

I was recommended by a few people to try this product. I followed the directions EXACTLY and it didn't do the job.

I didn't do my research before using this product until after. I had a little coolant seeping through head gasket before. After I had a full blown leak everywhere immediately. I should have stuck with gm seal tabs as they are highly recommended! Don't ruin your engine with this blue gunk. Now I'm $1800.00 in the hole with a new head gasket replacement. Best luck my people

it clogged up my entire radiator and heater core and hoses. do not use a used as was if you do use it definitely flush first did not recommend it
