I tested BlueDevil on a 1999 Ford Expedition that my friend was using to pick up his kids from school. It looked like the only place for this truck is a junkyard. It had antifreeze in the oil, a heavy smoke coming out the back, and overheating. The mechanic quoted him $2,000 to fix that blown gasket. I don’t think that car was worth that kind of money. He did try a few different sealers but they didn’t work. I suggested to try BlueDevil since it got many positive reviews. It was only $35 on Amazon. I started by flushing the radiator and put some new antifreeze although it was not required. I wanted to make sure that all the leftovers from the other sealers were gone. After following the directions I let the car idle for about 1 hour. By the end of 40 min the smoke and overheating went away. Today, 5 months later it is still running with no problems. My friend was happy he doesn’t need to get a new car right now.
Over 50 people reviewed this product giving it 4.1 out of 5 stars and over 340 people liked this product on Facebook.

Many consumers had very old cars that they thought would never get fixed by using a chemical like BlueDevil. They were pleasantly surprised when the vehicle started to work again. Most consumers said the product was worth the money and would recommend it to their friends and family.
“Fantastic stuff!! Overheating issues completely cleared up after adding to the cooling system. I would recommend this product to anyone.”
“Half-expected this wouldn’t work but it worked like a charm!! Great stuff – especially if you’re not up for monkeying with the thermostat and flushing repeatedly to remove all anti-freeze!”
“Great product, but you have to follow directions exactly. You must pour it in slowly or it will congeal. Worked for me on a 99 Dodge Intrepid with a head leak.”
“A Miracle in a Bottle! It worked on my truck with big 5.4L engine. Its been over a month now and no problems, the seal is holding up just fine.”
