BLUE DEVIL POUR AND GO HEAD GASKET SEALANT

Definitely patched my head gasket problem. Follow the instructions to a T and it seems to have improved the state of the engine. Initially, I was still having rough starts (probably due to the remaining coolant within the pistons) but overtime this has improved. Only time will tell how long this lasts. 5 Stars. *Note* If your car's coolant is leaking into the oil (milkshake looking oil) do not use this product as this can cause clogging within your engine which could lead to an engine replacement completely nullifuing this as a cheap solution to an expensive problem. This product works by using the high engine temperature, changing the state of this solution to a soild, to seal the head gasket. The oil is exposed to these tempertures leading to a clogged system. Please check before using. I'm far from an expert so do your own research to ensure this product is right for you. Good Luck

My car was losing coolant through steam probably head gasket issue. Believe it or not I've used more than 250 litres of coolant and distilled water in my car in the space of 4 months. I had to risk and use this blue devil pour & go gasket sealer after reading reviews online and watching youtube videos. I followed the steps in the bottle except removing my thermostat which was a risk. Its been a week and no more coolant loss, no more gurgling noises in the system, No overheating, steam has drastically reduced, at times no steam at all. Car was like a chimney before even after driving for hours steam was still emitting. I must admit for now the product from bluedevil seems to work very well.

Didn't work at all

My beloved Mitsubishi Galant Sport which I have owned for 8 years developed a leak in the head gasket and it was looking like curtains for it as the repair cost would have probably exceeded its value. It was using about a pint and a half of water a day, running on 3 cylinders at start up and bubbling air back up through the cooling system. Luckily I found out about head gasket sealants and it seemed Blue Devil looked like the most reliable. I simply followed the instructions (white label) - slowly poured it into the cold radiator with the engine idling, heater on max and left it for 50 minutes. It did its job brilliantly straight away. This was less than a week ago but it has been running sweetly since, has not used any water whatsoever, not misfired once and I have no bubbling back- pressure through the expansion tank, and the engine management light has gone off. The only thing I did differently to the instructions was that I had already taken the thermostat out a couple of weeks before, just to keep the temperature down. Obviously I cannot say how long this will last but I can say that this product is bloomin' BRILLIANT. What annoys me is that my local garage that I have used for most everything for several years didn't bother to tell me about the existence of head gasket sealants - and they must know about the stuff - even though they knew that I would not have the gasket replaced as it was uneconomic and was totally depressed about the situation. Maybe they will have a couple less customers from now on.

i bought this one because it had the most "good" reviews and since i have used it I haven't had any more problems so it seems to have done the job.

Worked a treat would highly recommend

Very good, excellent

did the job

Ich bin begeistert. Ich fahre einen 7er BMW von 97 mit dem 4,4 liter V8 und musste nach einem Wasserpumpen Totalausfall auf der Autobahn leider feststellen, dass der Wagen nach der reperatur viel öl und kühlwasser gefressen hat, soweit Probleme mit der Motorkühlung im allgemeinen hätte. Er ist auch relativ unrund gelaufen und hätte CO2 im kühlsystem. Also verdacht auf ZKD oder schlimmer. Da der Wagen Aber schon 400k auf der Uhr hat wollte ich jetzt keine 2-3k in Eine reperatur investieren. Durch einige (amerikanische) YouTube videos bin ich auf dieses zeug hier aufmerksam geworden und habe mir nach einige recherche gedacht ich probiere es mal aus. Nun was soll ich sagen, der Wagen läuft wieder wie er soll und das nun seit über 1000 Km. Auch kein flüssigkeitsverbrauch mehr. Bin mal gespannt wie Lange er so weiter macht. Ist halt keine reperatur für die ewigkeit. Das Zeug hat auch nichts zugesetzt oder verstopft, es läuft alles so wie es soll. Ist das geld echt wert 👍

Easy to use

It’s really work within 1 hour , I had KIA forte 2016 with blown head gasket which making pressure in coolant system. After I use it problem solved without opening Engine.

Works wonders to seal the air gap effect about 6 hrs.

Easy to use. I had a slight leak in my head gasket on my 2.5L 2004BMW Z4 which would pressurize the system. Pressure remained even after system went cold and there were foaming bubbles in the coolant so I knew it was a slight leak. Blue Devil fixed that and now no bubbles / foam in coolant and no retained pressure in cooling system after cooling down over night. It now remains to be seen how long this fix will last.
