Seized bolts? No problem.

I haven't actually used this stuff but I've read nothing but great reviews on the vintage car forums. Just thought I'd pass along the info.

Wow...looks good. I sure could have used that Saturday....

I'll have to check the autoparts store on the way home tonight....

Makes sense, especially with our aluminum engines, yes?

Just looked em up 15.68 a can here... might have to get me some me thinks....

If it will only work that good!!Someone who tries it please post your findings.It would be a godsend if it works especially on those pesky exhaust bolts.

Hi,

Do you think this would also come in handy for installing wheel bearings and such?


Thank you for your indulgence,

Me thinks it would. Seals might just slip in...

I have been banging on about this stuff for a while.
It does work...but you use a lot at a time. I pretty much used a can on 1 bolt.
Initially it was bought for its stated purpose, but I have used it help with electric motor bearing installs in the field.

Wow. If it works, great, but $15 a can is highway robbery. Couldn't you just use a can of regular compressed air turned upside down? That has the same "freeze" effect. Combine that with a can of penetrating oil and you just saved yourself $10.

I presume that this stuff is liquid nitrogen (or similar) to get the required -40 degrees. I don't think compressed air would get it quite that cold. It costs a lot more to get a broken bolt removed by an engineering shop.

Not sure if it is the same but I use it all the time for electronics. It might be a little cheaper.

I spent nearly 15 hours getting 4 broken exhaust bolts out of my 1100's head, and wrecked nearly $100 of tools (cobalt and carbide bits and one burned up dremel removing said carbide bit). Two of the four bolts were grade 8. $15 a pop would have been the bargain of the year if it worked!!!

yeah but will it chill a room temperature beer to frosty drinkability???

The Super Cold Spray 134 leaves no residue, so it must be different. Maybe the cooling stuff without a light oil mixed in.

Something else to try would be an ethanol + dry ice bath. The mixture sits at about -78C (-108F), and it costs very little. Get some denatured ethanol at the paint store. (The less water, the better. You could use Everclear but it's expensive.) Get a pound or two of dry ice. Put the dry ice inside a folded towel and whap it with a hammer a few times to make small pieces. Pour a cup or so of ethanol into a metal container. (Plastic or glass could break from the cold.) Use tongs or pliers to add a tiny piece of dry ice to the ethanol, which will instantly begin to boil. When it stops boiling, add a second piece. Keep adding pieces as the boiling subsides until it boils only slowly, and doesn't boil faster when more pieces are added. It is now super cold.

Be careful with this! While it isn't as dangerous as liquid nitrogen, it can rapidly cause permanent injury on skin or in eyes.

I think that it would be possible to jury rig something so that the cold mixture could be slowly poured on the bolt head. I would have PB blaster, or something similar near by to spray immediately on the bolt head.

Once the dry ice has evaporated, and the ethanol returns to room temperature, it is almost exactly as it was to begin with. Some water from the air has been absorbed into it.

(I used this kind of bath in grad school as part of the process of freezing cells in a manner that allowed them to grow again after being frozen in liquid nitrogen.)

Borrowed from another forum - "oh, its also good at chilling beer."
