How to fix your Head Gasket for $100 with Blue Devil Head Gasket Sealer!

Trust me, this is nothing like stop leak. We all know that most "pour in you radiator fixes" are bad for your cooling system. Blue Devil Head Gasket sealer, being a chemical based sealant, will not clog your system like other products that leave clumping particulates in your coolant. I can hardly believe it, but it actually worked. Watch the video see how to do it!

[@bromikrock]

Forgot something, I asked blue devil if it was better to leave it in so it keeps working. They said you can but it won't keep working as the chemical reaction is heat activated. Once you run your car and heater for the 50 mins the chemical reaction of the blue devil is done and so is any repair that happened is finished. Leaving it in longer doesn't do anything. I ended up draining it and putting in new anti freeze. Hope that helps anyone who goes for it.

[@triodeamplification5568]

I've seen a lot of videos on head gasket sealers and I have to say yours is the most precise,specific and easily understandable. I always use distilled water. Never ever use City water tap water from your house. House water is full of minerals calcium lime and it will eat your radiator up! You took your time and it is a relaxing video to watch. God bless!

[@TrailBendersOverland]

Thank you!! I’m glad you found it helpful. Always do my best 😊

@@TrailBendersOverlandhey man great video! I honestly wish I found it sooner, but so many other videos come up before yours, which I really don’t understand that algorithm on anyone’s device, but I’m very happy that I did find your channel and this specific video along with the one year after video for this one. I don’t know if you’ll see this probably not because you do have a lot of subscribers and comments on newer videos. I’m sure that will pop up first but, I was wondering if you wouldn’t mind me putting in my phone number down in the comment until you get it and then I can delete it so I don’t have too much spam lol, because I do have a question about putting the blue devil in my Toyota and there’s just a couple steps that you did that. I have a question on, but only if you don’t mind, I don’t want to make you feel pressured or like you have to or something, so just let me know, thanks! I’m planning on doing it by Saturday 3/16/2024. I keep holding back because I’m so afraid to mess up

[@bromikrock]

Your vid was super helpful. Did a lot of research and the yellow blue devil seemed like the best to take a shot with. I did call blue devil for clarity on one thing which was making sure your engine is cold when you add the blue devil since the chemical reaction is heat activated. I initially thought when the instructions and even video said let engine cool and then add sealer it just meant don't open your radiator cap when the engine is still hot to avoid injury but the blue devil rep said wait at least 2 hours after the final flush before adding the blue devil. Finished it on Monday 9/26/22 and so far so good. Was a little freaked out because I was still getting some bubbles at the radiator cap that day after it was all done but I think that was just air in the cooling system working it's way out. I'll repost if it all goes south.

[@jeffreymortimer8241]

Am in the Bahamas where is hot all year round, did a head job 3 weeks ago and the gasket lasted about a week before I noticed it started to mix again I was about to sell my car for little to nothing and blue devil cost about $80 bucks just for the 16oz pour and go version of it, eventually the auto store dealer convinced me that it works, so I bought it and in no min I saw it starting to take effect and work, I would recommend this product to anyone who gasket fails.

[@terrywilson321]

I know this is an older video but I purchased the same product. Chased an issue for months replacing radiator, water pump, and thermostat. Found out that you can buy a block tester kit for $30 and it came back as a bad head gasket exhaust leaking into the antifreeze. I tried a product called Kseal which is a pour and go solution and it didn't work. I drain my entire system loaded in Blue devil ran for 50 minutes idle and now it's sealed. Hope that it stays still for a long time but nonetheless I am impressed.

you used this for a water pump leak? wth... next time replaced the water pump. pumps cost around $80-100. ask a cousin or guy friend to do it for you. Its a very simple job, Minimum 30 min job. Dont ever do this again if you know where its leaking from. You can damage your engine using this stuff, This stuff is ONLY for people who KNOW they have a head gasket problem and dont have the money for gasket repair which costs $2k-$5k's. This is ONLY a last resort. Thats ALL its intended for nothing else.

My nieces jeep uses 3.5 G of coolant and the bottle says to use half for a 3G system. I used half but I think I shouldve used 3/4 of the blue devil. No overheating yet but thats because it takes a full week to start overheating from coolant lost/burning up/evaporating. I did flush the system out today at least 3 times before giving her the truck back and told her to save her money for a gasket repair. Not sure if it was my fault or the product didnt work.

​@@TrailBendersOverland I have a Blue Devil update. I brought my car to Cloverdale Express Oil & Car Repair cloverdalexpress.com in Cloverdale California. The owner is Jennifer and wow was she knowledgeable and thorough. She and her mechanic Isreal first did a pressure test that showed good compression. They recognized the misfiring as a possible coil issue but found out it wasn't that by running a test on it. Then they used a mini-camera in cylinder 1 that showed her there was a tiny leak from the head gasket into the top of the piston causing the misfire by getting the spark plug wet and as soon as the car warmed up, the expansion of the metal made the leak go away which allowed the car to run like normal. A coolant flush and water replacement with Blue Devil was performed. The engine light has stayed off for 50 miles. I'm going to bring back in after 500 miles to follow up and add the radiator fluid back in if all goes well. I'll give you another update when I can.

[@TrailBendersOverland]

My would drive normally for hours, then when I slow down to a stop it would start overheating. It would happen much faster when going up mountains or towing a trailer. Normal daily was almost entirely unaffected other than a slightly rough cold start in the morning. Blue Devil suggests if your engine can't idle for an hour without overheating then your head gasket might be too far gone. I'd probably still try it myself, since the alternative is much more expensive. Hope that helps!

I will do the procedure tomorrow, the thermostat housing is in one of those headache spots, so I just pulled the thermostat tonight, will rinse out the system tomorrow with a water house, & proceed.. I put the housing back on. Should I take the housing back off before rinsing or is it okay to rinse with it on? It's a real headache to get off, takes about 30-45 minutes, it's in one of those spots...ugh. A thermostat issue would not prevent the sealant from working, would it? Just in case I overlooked something concerning the thermostat, & still end up having to get a new down the road.. It's new, I wouldn't think anything is wrong with it though..

How is this repair holding up? Was thinking about trying the same thing

[@TrailBendersOverland]

It’s has been perfect. It’s been around 8 months now and I’ve done plenty of towing and pushing over mountains, which were situations where my issues would show up, and I haven’t had one issue since. It runs like new. I still can’t believe it. Just be sure to really follow the steps. Do the flushes, pour slowly.. etc.. I would recommend it to anyone who doesn’t have extreme symptoms.

[@matthewhooks452]

For a 4.0L V6 four runner, do you recommend the entire quart?

[@TrailBendersOverland]

I used just over half the bottle which was a tad more than they recommend on the bottle. I don’t believe it would hurt to use more, but I don’t think you need to.

[@chaseembrey6750]

My truck had water and coolant in my oil, will this fix my head if it’s that bad?

[@TrailBendersOverland]

Will the truck run on its own for an hour? That’s the main test. From what I’ve seen it might be too far gone for a solid fix by blue Devil. It’s my opinion that if the truck can run for an hour then it’s worth a try. If you do, make sure you thoroughly flush the coolant for using the blue devil.

[@jennygremillion8930]

Did you have to run the heater when you first poured it in and let it idle?

[@richardmartin2471]

Yes. On full blast

[@TrailBendersOverland]

You do need to run the heater so that the coolant will run through the heater core. However, you do not need to run it at full blast. Running it on low will allow the coolant to flow through and will not disperse too much heat. You want the heat to build up while you wait. Running the heater on high will rob you of some of that needed heat.

[@ryantrogdon3633]

@@TrailBendersOverland hey my heater is not working, I think because of whatever is causing my car to overheat, it was working before, so my question is will the work still?

[@matthewhooks452]

Would you recommend pulling spark plug #6 during the sealant process for better penetration? Thank you 🙏

[@TrailBendersOverland]

Damn! Hope you got a good deal on it. I'm getting ready to make a 1 year video on my experience. Long story short, this stuff worked like magic for me. Still running good as new! I would definitely leave your spark plug 6 in. The Blue Devil fluid needs heat and oxygen to solidify.. so you'll be needing that spark. There shouldn't be much water running through the cylinder with the engine on. Cold start is the worst cause the water has had time to build up.

[@matthewhooks452]

I got the shaft real bad. I appreciate you replying so quickly man. It’s definitely something I didn’t buy to want to pour money into, I bought it for work to keep miles off my tundra and something with better mileage.

[@TrailBendersOverland]

Also, I left the blue devil in for a few days, the company says it can’t hurt. But I didn’t fully trust that my engine got hot enough to make the chemical reaction happen, so I left it in and drove it around. Then I drained out enough water to add the coolant.

[@ClaytonMorrow]

Sorry if I missed this - did you do a full flush sometime in the last 6 months and get back to having antifreeze in your 4R? Do you still think the vehicle should be run for a few weeks with the water/Blue Devil as-is and then flushed? Looking to do this on my 4R and trying to plan my attack, haha.

[@TrailBendersOverland]

Good question. You didn’t miss anything. I probably could’ve talked about it more clearly. I actually let it run for a few months. That much time is definitely not necessary, it’s because I was pretty busy and never got around to it. Running it for a few weeks I feel is a good idea, not sure but it made me feel better about it. That said, within my first hour of driving I noticed a difference it how it runs and ever since it’s been amazing. That was around 8 months ago now. When I got around to putting the anti freeze in I didn’t do a full flush, just drained enough to add anti freeze. Blue devil says it’s perfectly safe to let it mix afterward.

[@l0rdraider1976]

You only used half of the bottle? Why not the whole thing?

[@TrailBendersOverland]

There’s a graph that shows recommended amount to use based on the size of your coolant system. If I remember right it’s on the bottle. I just followed the recommended amount.

[@jmreynolds255]

@@TrailBendersOverland did u have bubbling in your reservoir when u shut it off and could hear the water rush through your heater core. I'm asking cause I am having these symptoms.

[@TrailBendersOverland]

I had bubbling when on, shit off, water sounds in the heater core, rough idle with cold start, and random rough idle here and there. Daily driving didn’t cause any issues, but after a few hours of driving, or pushing up a big hill I would overheat when coming to a stop. This is from having bubbles in the coolant.

[@TrailBendersOverland]

The bubbles you see are from exhaust getting into your coolant.

[@TrailBendersOverland]

Also, be sure that your system doesn’t just need to be burped. Part on a hill nose up so your radiator cap is higher than your heater core. Run the truck for 15-20 min with the heat on. If the bubbles never stop coming then that’s a bad sign for your HG. If your daily driving is mostly normal, then this still will most likely work for you.
