Induction Heater

[Paul]

Anyone has used induction heater to loosen rusty bolt/nut?

I need to change the oxygen sensor on my Nissan Versa. I do not have acetylene torch.
During my research, I came across induction heater.

I found 2 products:
Bolt Buster
Mini-Ductor

Yes it works but for the cost you could pay a garage many times over to remove it for you, Personally I use a 3/8th impact gun with a flare nut crows foot to remove stubborn 02 sensors. if you cant remove it will the tools you have buying that section of exhaust used is also another way to go, OEM exhausts are only a few bucks per section at breakers yards and for the hassle it can it save may be worth it.

this and your favorite penetrating oil. worked for everything I have used it on. Keep in mind Mapp gas blows propane out of the water, it will get cherry red easy and fast.

Thanks for the ideas guy.
There is a pick-n-pull yard in my city. I may try that.
I will keep MAP gas in mind when I need to remove rusty nut or bolt.

I used penetrating oil and my impact wrench to remove rusty nuts when I changed the muffler on my 91 Civic 3 months ago.

For the price of an inductive heater you should definitely just buy a oxy/acet torch they are way more useful. IDK what I would do without mine.

If you can’t afford it MAPP gas can be a good option. MAKE SURE you get a good torch head (one that creates a swirl flame) it will really increase the heat output. I’ve got a ton of use on my TS8000 and it’s been awesome. I just used it yesterday to braze a rod to a bolt because I didn’t feel like getting out the welder or my oxy/acet torch.

Drive around and get the exhaust as hot as possible. Then use the MAPP gas to add as much additional heat as possible. If it still won’t come out, try cutting off the body of it with a hacksaw or something then use a regular socket and impact on it.
