Is blue devil transmission sealer safe to use on dual clutch transmissions?

i put this in one of my fleet vehicles the next day didnt make it 35 miles had towed to shop this stuff clumped up and took out aux water pump and thermostast and had to be flushed out cost $1745.00 for repairs

I had a severe leak even after replacing gaskets, worked great after usage

Good video love this guy

It's works great for my Corolla 02

Can I add Blue Devil after A oil change?

You 0:21

Why use happy smiling people who have nothing to do with this vlog . You loose creditability my friend. ,!!

Im scared -

This stuff turnes into glass from the heat of gasoline combusting when it squeezes through the leak in the head gasket into the combustion chamber. It is actually stronger than the head gasket itself.

Had an odd experience, installed a bottle in my Celsior and it was fine, the next day there was a TON of noise/aeration in my pump reservoir. I flushed it with MOC and conditioner and bled the system. Currently I do not see any leaks but it acted like I had no fluid in my power steering system. Again I’m driving it and I don’t see leaks but it was very odd.

You should have told me that before I did it😢 0:46

Hi does it work on Honda CR-V?

Did he say 15 or 50 minutes

How am I supposed to run my car without the thermostat attached. Dumb

This guy looks like he knows nothing about everything.

Just to be clear, once I’m done idling for almost an hour I can just put some antifreeze in the radiator, I do not need to drain the blue devil?

Very good product.I have used it and it's help me very much

What if you don't have a radiator cap all you have is a reservoir tank

Question is does thermostat have to come out

What if you don’t have a heart coil

Have a rear axle seal leaking . Is this OK to use in the rear axle since they use 90 or above oil?

So do you put Freon first then red devil product

Follow up on my earlier comment as of yet no issues with a 1999 Mitsubishi spider and still no issues with the 2008 dodge caravan that had a blown head gasket

Do i have to remove the old oil to?

That Devil works really good 👍

Is the radiator and where you put coolant the same place?

One thing that is not mentioned on the instructions label is the fact that you need to remove the thermostat before starting the treatment. This solution is not going to work on gasket leak to the manifold. How can u tell if that is the case by checking the exhaust pipe. If water steam and water is dripping constantly when the engine is hot and the thermostat is open then u know that is the case. In this situation do not waste ur money cause it won’t work. Besides this u must take ur thermostat out and flush the coolant system(the radiator and the heater)a few times to make sure the solution is going to circulate inside the system freely. The instruction on the bottle is not complete and correct. It is to some extent misleading cause u need to do it right to get results and to prevent the possible damage that it might put to ur car. As far as I concern this solution works temporally on small gaskets leaks.

Im planning on trying the heavy duty head gasket sealant but I feel i shouldntry to flush the system first because is be worried this may adversely affect the sealant. What should i do. I am not even sure if can run the car for 10 minutes. Ive been avoiding trying to get it too hot. Also i had a pin hole leak which was why i overheated and i ran the car for about 45 minutes at idle while trying to jump start another vehicle i thought i had no coolant at all because i had no heat and when i touched the radiator cap it didnt feel overly hot so i stupidly cracked the cap and i had a mini geiser. I tried to nurse the car to the closest parts store as it was pouring rain and the car went into the H and it stalled so i pulled over immediately and got towed. Luckily it was such bad weather and heavy traffic i guess there are pros and cons to this as i may have been able to get it to a lower operating temp had i been moving more air through the radiator. I got the car home and checked the oil immediately and luckily o didnt have the milkshake of death. I however couldnt get the car to run. It seemed starved for fuel. I added gas and scanned for codes and had a cylinder 3 misfire. I had a new coil and plug on hand which didnt really look all that bad. I would be able to occasionally get it to fire off but it would run bad and stall. Fast forward 7 days i didnt touch the car because i was mentally regrouping working on another car. But on the 7th day i just hooked up my jump pack and the car started asnif there was no problem until i checked the oil and duh duh duh milkshake. Its a 2008 infiniti g35x and im trying to figure iut if the coolant entered the oil a different way. The pin hole leak was in the poorly designed oil filter coolant hose which for some reason is a 10-11” metal section coveres in rust scale fortunately the pin hole was close enough i bought a slightly longer rubber line and for good measure i applied high temp water proof silicone around the pin hole before installing the new hose and double clamped it with regular worm gear clamps. Iv read these oul filter coolant gaskets can let go but im unsure as to weather the coolant can actually get into the oil there. Any help from anyone would be appreciated thanks.

So what he’s saying drain the old cooling out give it 1 gallon of water run it for like 10 minutes drain it. Add blue devil in and 1 gallon of water then run for about 15-20 minutes. Drain again and then put the right amount of coolant back in.?

what I have to pour it in the top radiator hose? Where is that at?

It’s specifically says not to pour it in the reservoir or overflow tank. If you don’t have a cap on the radiator, you take the upper hose off and pour it in there.

Does this remove rust?

Does this remove rust?

Is it necessary to burp the system right after installing the BD repair and coolant?

How much blue devil for 2.4 engine

I flushed my systems 7 times already had heat then lost it again. So can i use this product in my system that has dex-cool in it besides dumping it all out again. Maybe let it run in my system with dex-cool and not water? Or does it have to be water?

Drive for 6 hours or idle for 15 minutes wtf

So do you have to take the thermostat out or not?

There's BlueDevil pour-n-go head gasket sealer, BlueDevil pour-n-go coolant stop leak, BlueDevil pour-n-go radiator & blocksealer. You're using for gasket so does it matter which one you use?

Replaced all 3 seals on my polo 1.2 tsi and after all that excessive oil still spilling out my timing case cover also wetting the timing belt. After watching this video I'm quite certain it's the rear main seal especially after hearing the causes as well. I'll come back a few days later for confirmation

So after after draining the first water cycle do I put the plug back in add blue Devil and water on top of it? How much blue Devil do I use this came highly recommended from a autozone employee just bought the stang and I’m trying to restore the coolant system as well as saving the engine before any catastrophic damage

This stuff is crap. It clogged my heater core. Run as fast as you can away from this snake oil.

Would it work on a head gasket that is putting pressure on the coolant system??

My head is blowing steam, and cannot hold a thought, will BlueDevil Pour-N-Go fix it?

I used this on my Honda Odyssey. I had a small leak and after two weeks it seems like the leak has stopped. My only concern was that I am almost due for an oil change but after watching this video I feel better about draining the old oil with the additive in it.

I purchased this product in autozone after reading all the reviews . I followed instructions to the T. Pretty easy and hard to screw it up, I even watched their KZbin video on how to do it. Anyway, my 99 4Runner wasn’t that bad had a very small leak and only smoked at cold starts for about a minute or so.. after using this product it made my car run like crap and smoke doesn’t stop coming from tailpipe . Excessive smoke as well. This product made it worse . Before at least it was drivable with no issues. I called their customer service and they provided 0 feedback or opinion. Don’t waste your money.
