Can I remove 40 year old seized bolts using an induction heater?

- Using a Solary Magnetic Induction Heater, I successfully removed all 12 of the 40 year old exhaust manifold bolts on this PRV V6 motor.
The induction heater I used was bought on Amazon and is simply amazing. It prevented me from snapping any of the bolts off and having to drill and tap new threads:

Ordered one last week, used it on a Cummins ISX today, tried everything to get a flare nut off, nothing worked. Broke out the induction tool, and within two minutes, the 22mm flare nut was off. Worth every penny!
What the name of it?
@@mujeebshahwali5072Amazon, look for any of the induction nut heaters with the blue hard case. All the same manufacturer. They work.
And you hadn’t destroyed the hardware with the other methods? That’s experience, right there.
Wow! 40 year old bolts may be our new record! Thank you for the review. Our H7E induction heater is a convenient solution to stubborn nuts and bolts 😊
Send me one to test 👋🏻

I use 1 everyday doing alignments on tie rods and camber bolts among other fasteners quite often. Probably in my top 3-5 favorite most convenient tools to have.
I would think you would compromise the integrity strength of the steel
@@dontbeakaren6145 that might be true but i don’t think daily driving excedes even the reduced strength
@@dontbeakaren6145 the strength of steel returns to normal once cooled back down. I’m a welder, I should know..
This tool is especially good if you’re going to replace the bolts and hardware anyway just in case 😉 👍
@@cruisethewhip as a welder you should know welding makes steel weaker especially in the haz. It's known that steel begins to soften around 425°C and loses about 60% of its strength at 650°C. This is why heating or bending any metal causes microscopic fractures and stress points. I would never reuse a heated bolt that would compromise the integrity of its strength especially a bolt that is under stress or pressure from moving parts. Also for an example there's a reason why motorhead bolts snap when removing them cuz they've been heated and cooled multiple times.
I used one today to free a 60 year old seized track rod end (1964) - brilliant bit of kit!👌🇬🇧🏆
That tapping is exactly what an impact does. Just in slow motion. And without snapping off the stud.
Fyi... Smacking the wrench with the palm of your hand leads to nerve damage over many years. Learned that one the hard way.
If you wire wheel some of the rust off it will heat up alot faster!
thanks for the tech homie!
A spritz of penetrating oil on the dry rusted threads would have helped.
I do that tap think too. Works great. I dont have your heater but use a torch.
Hint put oil on after heat it will cool it quicker and get sucked in the threads as cooling air contracts.Makes a major difference.
Could it catch fire from putting oil on it when the bolt is still red hot?
@@faYte0607 Yep it does if your on orange or red heat, for a second or two. Obviously common sense says, petrol fumes, thinners, flammable gas in the immediate zone is a no no. Ive 50 years experience in oxy acetylene torch use whilst it will get the job done there is orders of magnitude more risk of fire, with moderate common sense an induction coil is of minor risk...hell i bought one!
Great video, sir. I am currently working on my used Pontiac g3 2010 and am changing the rusty brake lines and fittings for new ones. Can I use this to heat up and remove the old brake line screws? I have been already spraying PB blaster and already tried nut and bolt extractors. Also, I am new to car DIY, if that detail is important.
amazing .
Looks fun
Also, just from the past 30 years of experience with anything electrical, it would’ve heated that bolt to a glowing red hot miniature sun in probably less than a minute, if you didn’t use a general use extension cord and plugged directly into the outlet…. You could also use a super heavy duty 10ga. or heavier extension cord. You’ll still lose a little bit using one at all, but much less than the standard gauge cord you’re using…. Just food for thought… thanks for the demo!!
Thanks for your comment Mark. I posted a question on Amazon to find out the length of the cord and what gauge/length of extension I should use. Neither the puchasers or the seller responded. I'm going under my car to remove/replace the O2 sensors and the cord looks only long enough for bench work applications. Cheers
I need one of these I have broken so many manifold bolts and header bolts
I bought one and it broke almost immediately. I wonder if the more expensive ones are better quality? They look the exact same though. Do any of them have a warranty?
Сэр, я очень доволен этим видео, чувствую, что оно помогло мне в работе, и я очень благодарен.
I'm buying one!!!
interesting, I haven't seen one of these tools until a couple years ago. But the concept has been around for many years. I had a small heater like this almost 40 years ago, that you stick the metal coil in a cup of water or coffee to heat it up. I think it cost like $8. Whereas the bolt warm by a company that Snap On tools sells one like this for over $500.
The water heaters have a similar shape, but those aren't induction heaters, just resistance heaters. The shape of the water heaters is just an easy way to get more of the heating element into a small size.
@@hwingerrr5680 explain....in detail the difference how these operate. don't get all technical on us.....dumb it down to where we can all understand it. 🤨
I’ll try…the coffee heater is designed to electrically short in a safe manner. The short heats the coil which heats the coffee. Remember that you must keep the hot coil submerged in liquid, or it will overheat and break.
The bolt remover works by running an electrical current through the coil which forms a magnetic field. When this field is placed near another metal object it will heat it up but, the coil stays cool(ish) because it was only generating a magnetic field. Just like an induction cooktop.
@@Chevroletcelebritywires(metals) have resistance so they release some of the energy as heat. The coffe heater mentioned above works by heating up a wire that you put in the water via this resistance. And induction heater archives this by magnetic fields that induces currents in the metals, heating them up by resistance. Basically the first thing, but wirelless.
I see this tool is 200 for the 8 coil and 245 for the 10 coil
I’m considering buying one of them.
That nut should have gotten red hot,and it didnt
thank you
Shouldn't you shock the bolt with water after you heat it? My understanding is the heat is breaking the bond between the bolt and block unlike heating a nut which the point is the heat expands the nut and therefore comes off easier. Since it's a bolt you don't want it to necessarily expand.
It was a nut he was heating, not a bolt. Did you watch the video?
What if oil is still in the engine
Impact wrench on the proper torque setting would have that off in 5 seconds
Hands as hammers 🙈
Does it also work on a bolt head through a bushing that’s seized in the collar? Or only on nuts
It works on bolts and nuts. I don't know if longer bolts will work as well as it will only get part of the bolt glowing red hot. I don't know how much of that heat will transfer down the bolt.
@@jlattin21 That would make for an interesting experiment. Thanks for the response
@@jlattin21 should work as well as a torch, so not that great.
It would be the same as using a torch. A torch would also only heat the head, but of course the heat travels to the threads
Is there any tool like this for sale large back hoe attachment pins?
Is it something that a regular gas torch wouldn't do ?
Mostly heat concentration. A torch would likely do the job but you risk heating the cylinder head more broadly. If tolerances are tight (some engines inexplicably have no exhaust gaskets from the factory), it's probably best to minimize that.
Indeed. Since my last comment, I purchased and used an inductor and I must say that it works fairly well. Love that thing now. :-)@@kylezalewski8948
These are nice for working around heat sensitive materials like wiring harnesses, rubber hoses, o-rings and seals, etc. Great for tight areas where a flamethrower just causes too much collateral damage.
Гайку нужно разогревать до красна,а так вывернули шпильку,чем добавили себе работу,да и прибор слабоват.
It removes seized nuts not bolts
I'm need the
That’s not a 40 year old engine
You're right. Since it's from a 1981, it's now 42 years old and not 40.
I didn't see a bolt removed, that looked like a nut. a torch would have been a lot faster.
Oii
Will this easily get off my crankshaft bolt?
It certainly wont hurt. As long as you can get the heating element around the bolt, it should be able to heat it up until it's glowing.
