Blue Devil is worth the price. Flush the radiator as instructed, apply the solution, and drive your vehicle with confidence that Blue Devil will work
So far, so good. Blue Devil seems to be working, as I see no leaking from under the head or intake manifold. Haven't put many miles since treatment, so a little more time driving will tell. I did not remove the thermostat and replace with a new one, as instructed, but seems to have worked anyway.and engine runs cool. Blue Devil is definitely worth a try, especially for the cheaper price through EBAY.Read full review...

Nephews 1995 Honda Civic
My nephew's 95 Honda Civic. Blew between cylinder into the water jacket,so white smoke , leads to less water then overheats.
Blew out white smoke but not alot.
First of don't rush into pouring blue devil in. I've been wrenching over 30 years. Before you do it ;
1) Do a real radiator flush. I used Prestones Super flush. Cleans metal surface of head to block for better bonding. TRUST ME IT'LL WORK !!!!
2) Completely flush system out with water to rinse out Prestones Super Flush and just please follow the EXACT Directions.
3) With radiator empty ( and engine cold ), pour ( Blue Devil ) in the right amount needed for your vehicle , top off with water and top off overflow tank, start car and turn heater on HOT fan on high for the EXACT time no more no less......
My nephew is a happy camper. Now that being said he cruises all over on the Big Island and up that steep drive to Maunakea ( Big Island Hawai'i ) no problems.
Car never over heats , idle is smooth , little more umph in the motor, and everything is working like it never happened.
Believe what you want, flushing out your system makes perfect sense doesn't it ???? Same thing like painting a car, you sand it down and clean it paint sticks better. Like welding clean surfaces well the weld fuses much stronger. So too is the molecular bonding.
FLUSH WITH PRESTONE SUPER FLUSH FIRST. THEN USE BLUE DEVIL. YOU WON'T BE SORRY...GOOD LUCK TO ALL GOD BLESS FROM DA HAWAIIAN ISLANDS ...BRADDAH "D"

No doubt this works
I was very very very sceptical about using this because my car would overheat within 10min of just sitting at idle and I was dreading the point that I'll need to get the head gasket changed...so I seen couple vids online and came across a few a noticed the blue devil so I was like what the heck what do I have to loose so I offered it and followed its steps and all I can say is wow this stuff dose work...after a few days of just letting it run about 10minutes I was still scared to let it run longer...but then I had it sitting on for about 2 hours and the temperature stayed at normal the fan would kick on and off here and there but yha ran fine I even revved it up 5k 6k 7k....nope not one issue...I'm very satisfied with the outcome and all I can say is THIS IS SOME STRAIGHT VUDU JUICE FOR CAR ENGINES THAT OVER HEAT LOL 😁 GREAT GREATTT PRODUCT!!!!Read full review...

Blue Devil
Too soon to say if it worked, but I have seen improvements, one is antifreeze stays where suppose to be. Make sure to follow the instructions, and if your thermostat is on the bottom, you be flushing back out at the end, no biggy just dump back into the vehicle.
Highly recommend trying it.Read full review...

Bad Head Gasket Fix
My 1990 Corvette had typical symptoms of a bad head gasket. I followed the directions to a "T" using the Blue Devil. The billowing of steam out of the tailpipes, the bubbling of coolant out of the reservoir, the coolant in the oil, the sputtering running of the engine all ceased following treatment. I've been driving the Corvette daily now and it seems perfect again. It will be interesting to see how long the fix lasts.Read full review...
