Reminds me of what car dealers do, then sell the car to some innocent person. Never put this shi_ in any car you care about. Fix the car properly or make a decision to use this then run it into the ground.

Just something to point out if you read the bottle it specifically tells you to only use half the bottle if your cooling system is 3 gallons it goes by coolant capacity

Didn't do a compression test, therefore didn't properly diagnose a head gasket leak. Fail. I'm guessing there was a leak in the intake manifold causing coolant to enter the engine through the intake, which is a problem easily fixed by these sealants.

Completely follow directions.
Flushing, disconnect heater core, slowly adding sealant and running at high RPM per DIRECTIONS.

Why do they call it Blue(gives you the blues) Devil(not a trustworthy character, evil) if it works???  And why does it cost so much ($55 at WalMart) is the Devil greedy? I don't trust the devil blue or red in my engine.

If people really knew what chemical is in the bottle they would understand why it works most the time! Do exactly what the directions says, what the heck you got to loose your car is shot the way it is. Spending 1,500 or 50 bucks, no brainer. Too many good reviews for it to be crap!

Steel Seal for Cadillac Nothstar engines is $250 the other Steel Seal is $89.99 Just Google it and go to the site. I been seeing and hearing about that BLUE DEVIL here on YouTube and to each as own.... it's just something how something in a bottle that cost $10-60 sitting on a shelf can fix a major and costly repair in less than an hr.(wow) Using any of the miracle wonders in a bottle is like playing Russian Rulet...Powwww You go to jump in your car one day and that shit don't start cause the motor done locked up on that ass and the crazy part is it didn't give no signs that it was about to happen and your ass far as hell from home looking stupid needing a tow truck to get the fuc home or somebody to come get you.

I bought this last week for my 2004 Hyundai Sonota. It worked like a charm. It smoked for about 10 minutes then it totally stopped. Engine Compression went from 30 to 120psi. I was totally impressed.

It worked on my 97 seville for about 3 weeks until i stomped it i guess it blew the crap out of the hole.dont punch your engine you might be okay :{ im gonna try k&w block seal.mine isnt even bad the car runs great no missing just uses a little bit of water every few days.i have a 20 pound radiator cap on it cause it was leaking out my overflow hose which means it was building up more pressure than my 16 pound radiator cap could handle

BEWARE! I took my car in to be diagnosis for a SMALL water leak found under the car after it had been sitting for two days....my Mechanic pressure tested and concluded that it was leaking from the back middle of the head gasket, he put in Blue devil stop leak and my car overheated on the 4 mile drive home!? It had NEVER overheated until that drive home from the mechanics shop. What could cause that? I asked him if he thought it was the stop leak clogging the thermostat and he said NO. Sorry and hung up the phone! I ended up having my radiator blow open on me and after having it replaced by another mechanic (who said it did not have a leaking head gasket,) the car still over heated and we had to put a rebuilt engine in it. Because the stop leak had clogged the engine ports. I would not recommend anyone put this in their car!!

When they say "top it off with water" do they mean the radiator should only have water (not coolant) and Blue Devil or coolant and Blue Devil. I have a new radiator and fresh coolant so I'm curious

Used Blue Devil seal good for differentials

I had a damp spot on my middle rear differential seal decided to use this crap as preventative care; 8 days later it ate itself through the right hand left hand and middle seals fluid everywhere; took to a rear end specialist had to replace all seals the mechanics had never seen anything like it my entire rear seals had been softened up to the point they did not exist. $1000 in damage paid

The modern cars are not like the used to be. Taking the thermostat out was a routing thing, easy to get to. On my Dodge Intrepid they have the thermostat hid away behind the alternator. You have to take the alternator out to get to the thermostat and taking the alternator out is a major job. I used K&W Nanotechnology. Taking the alternator out is recommended, if you can. It worked pretty good with the thermostat in but I ain't putting anti-freeze until I absolutely have to next winter because from previous experience and what I have heard these sealers start going bad again once you put antifreeze in.
