- As seen in our previous video using the Mini-Ductor Venom. We were asked how it worked on exaust bolts.. so here is a look.

I have a 2009 6.2 GM motor that needs new exhausted manifold bolts! Nice! Oll have to get me 1
would love to see this pull old manifold bolts out of a FE motor, THEN i will truly be impressed
I love at 1:08 when he realizes he can't use it on that bolt
It's worth noting here... do NOT reuse these bolts/nuts after heating them.
I'm sure you guys know better, but some viewers may not.
Correct. This video was originally done just to show friends/ family. And Correct, using those bolts was never an option.
It's worth not having to deal with broken bolts.
Can you explain why not??
@@derakc.2783 You're heat treating the metal. It become softer losing its intended strength after heating it up
I bought one of those things specifically to remove an M6 bolt whose head snapped off when I attempted to remove it. I was able to get about a turn out of it with repeated heating and liberal use of penetrating oil, but then it just froze solid with the block, and eventually snapped off.
@@sorryimajerk735 Yes, of course. I ended up making a little custom fixture to allow me to drill it out very accurately on center. I must have put over ten hours into removing that single bolt.
Do you still use torches for bolt removal or does the induction heater take care of everything?
It takes care of everything what’s the point of the tool if you still use the torch
Yes, still use a torch when needed. This tool is used way more in our shop.
Many places on special intrest vehicles where a flame could NOT be used. Our later videos give a couple examples.
fancier looking equivelent to a 19.99 BernzOMatic... I like it!
How does it actually work? I thought metals expand when heated so should it be tighter?
Sorta, the bolt isnt stuck because its too tightly pressed against the bore, its because dirt, rust and other material has worked its way into the threads cause it to seize. do to differential expansion (the whole doesn't get all hot at once, so i doesn't expand all at once) helps break up the stuff holding the bolt in place
Rust expands making it almost like a glue bond heating it reduces the rust to carbon enabling the removal.
How big can the bolt head be? Would like to put on a brush guard but bolts are rust welded in place. Yes, I know I would be replacing the bolts.
There are many different size tips for all kinds of Applications. Look up Induction Solutions.
Can you use this on steel exhaust manifold bolts into an aluminum block without damaging / warping anything?
Nice and a A Thumbs Up Liked.
If you get an induction tool, wear thick leather gloves not vinyl dirt gloves, things get hot
Pussy
How does heating the bolts make them looser? Shouldn't they expand, thus making them harder to remove?
Heat makes the bolt expand, since it cannot expand sideways in the hole, it expans upward and thus removes the torque that was on the bolt when it was installed. Some bolts that are very rusty and the threads have been seized this thing will not work on.
Although this inductance tool is very useful it's limited to the size bolt head it will fit. An oxygen and acetylene torch works just as well on any size bolt. Heating and expanding the bolt breaks the rust bond making it easier to remove.
Multiple sizes of attachments for all sizes and types of situations.
And as most say, " use a torch ".
Check out the video we posted where flame would destroy a 54 Corvette steering wheel.
@@sorryimajerk735 Anyone can be a mechanic if they have the right tool. It's the guy who can do it without the right tool who's the real mechanic.
@@jamescosta9120 To be a smart mechanic and a stubborn idiot are two different things.
@@jamescosta9120 even if i gave you the tools to do a timing chain job you wouldnt accomplish anything.
@@jamescosta9120 That's just not true haha
Nice.
Does it come with a right angle adapter for tight space?
You can bend the attachments.
maybe im a skeptic.. but i would like to see you try one bolt without the tool, and one with..
Are you skeptical of using a torch? It’s physically the same action, applying heat to the bolt, just in a much more localised, controlled area. In so far as just heating ferrous metals go, an induction tool like this is quicker and better than a torch that people use for the same activity 💁🏼♂️
@@dylanshandley1246 tbh i am skeptical of heat to be begin with. Ive used it and it doesnt do much. Nore do penetrating fluids.. every bolt ive sprayed with pb blaster and so forth and let soak.. when i unbolt then finally the next day or hours later.. the penetrating fluid didnt even get 1 or 2 threads down lol. Project farm did a video on penetrating fluids and i never saw any fluid get into the threads.
I know heat is auppose to break the rust weld of the bolts.. but wouldnt a hot exhaust manifold already do that when the engine is cycled lol..
Only thing i can see heat doing is making the bolt weaker when you try to take it off.
Just stating ny experiences working on classic cars for 14 years. The best thing i noticed to get bolts or whatever out.. Is impacts. No i dont meanan impact wrench but i mean a dead bow from a hammer on a bolt head or whatever usually does more than heat. Besides a bolt threaded into any metal wont get hot that far down the bolt. The head or block ect whatever will just act as a heatsink.
Heating a bolt will also make it larger than the diameter of the hole it goes in.. So it might actually make it harder to get the bolt out. Freezing them might work better actually.
@@jeepsblackpowderandlights4305 when you heat a bolt, it does obviously expand, but by doing that it’s compressing whatever is gumming up the threads so that when the heat does sink into the surrounding area and expands that a bit, while the bolt is smaller because of the heat that it’s sunk into the surrounding metal, it’s got a larger gap between the thread itself and the bolt itself, allowing something like a penetrating oil to slowly wick down along the thread through that small gap, making it all the more easy. The best bet I’d wager, is to heat the bolt up so that it sinks all the heat into the thread where its making contact and expanding that a bit, and then using an upside down air can or something to try and quickly cool the bolt so that there’s a significant difference between the ID of the hole, and the OD of the threads.
@@jeepsblackpowderandlights4305 I kind of have to agree with you. I do find that heat works but you really have to heat the bolt till it’s basically red hot. Also because the two objects are different coefficients, when you heat up just one object, they expand at different rates. This is part of the reason why I think welding a nut on works so well. If all you are using is a propane torch I don’t think it will do much.
@@ryanjohnson8340 exactly !!! Just getting it smoking like this tool does doesnt do much.. i saw a video of this tool being used.. and th3 guy could hold the bolt only 2 inchs down the threads... that doesnt show me anything.. but all this does it heat the head of the bolt.. imagine if its in the head which absorbs the heat like a heatsink.
Hanging that motor by only one top bell housing bolt is expecting a bit much.
No penetrating oil as one sits under the motor........
The penetrating oil cannot travel against gravity and if it did the threads would be pretty wet or burned off by the mini ductor. Use ya brain.
You're supposed to say if this was paid or sponsored in any way.
Was not paid for by anyone but myself. Lol.
Video was originally just to show direct friends/ family.
Now on the cats
how is this better than a torch? never mind i read the comments, works in special situations only where you cant use a torch. w/e
Tool prob won’t fit in most places while working on the car
Has many different attachments for different sizes and situations.
