My 02 civic overheated three times! Bought a bottle for 29$, flush the the system and put the whole thing in. NO MORE OVERHEATING.

Can you give direct instructions for those who have to add the coolant to the top radiator hose?? Do we add water inside the hose with the blue devil?? Or pour the blue devil in the hose and the water in the reservoir??

Do I need to change my oil after applying the duke blue devils head gasket sealent

When you over heat the engine you can potentially damage the thermostat. Replace it.

Not sure how long this will last but my Mitsubishi Pajero had a blown head gasket and still going strong 6 months later no loss of coolant and the motor i have been driving hard with a caravan i recommend this product the mechanic said he followed the instructions to the T and has always had great success .... Question BlueDevil what timeframe would you see this lasting for ?

[deleno]

Hi there, did you say let engine run for 15 min, or 50 min.? Thanks

[tonyluna]

works great 💯 ford 2011 lariat 5.0L
now lets see how far it goes

[godatgaminggames]

Are you suppose to check again after this? Just a questiin

[kevinehrhardt]

So after i add water to the system and the blue devil let it run for 50 minutes. Then let it cool. Then do i need to drain all the water back out and add the recommended amount of coolant back in?

[mariahhothan]

Do i leave the hose coming from the overflow tank in/on while its in the idle phase or do i just let it sit sucking in air?

[arturoromero]

Hi i need help new to this.... Been working on my car and i noticed that it does not look like it has a headgasket so i was wondering of i can just install the blue devil fluid? Or what do i have to t
Do? Trying to safe money here. Cool videos. Just a noob here. Thanks and god bless.

Is there a way to use this product, if there is not a radiator cap available..? I have none, so I can't pour the product slowly (i read that I can't pour it through the plastic container..).
Thanks in advance!

[CaseeColdd]

Do you top off the reservoir after putting the blue devil in the radiator?

[CoogiMane]

Is there any recommend instructions for apply a full bottle longer than the 50 Minutes recommend time of idle?

[Percocet]

If I added blue devil a while back and need a coolant flush will the blue devil flush out as well??

[ingolfurarnar]

Why do I need to remove the thermostat?
And why can't I use the old one again if it's working fine?

[kimberlysmith]

If my oil is milky do I have to change the oil before letting it idle? Yesterday someone put it in for me and we didn't change the oil and my battery died. So my friend came over a few hours later and crunk it up and let it idle for a little bit to charge my battery but said we couldnt let it idle for the whole fifty minutes because we didn't change the oil. If it's milky do I have to change it? And will it not work now since I put the Blue devil head gasket sealwr in yesterday?

Is Simple Green Heavy Duty cleaner a comparable flushing agent?
