Seized bolts? No problem.

...........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.........

Or you could just spend $15 and do it safely.

Yep, I too will vouch for this stuff - helped me when pulling another set of carbs apart - just wish I had it for the first set!! You do use a lot, but as Zooks inferred, look at the bigger picture. Think you guys in the US only pay about a tenner a can too!

Well last week I spent 2 hours gettin 3 exhaust manifold flange bolts apart on the drivers side of the Caprice...ended up breaking them off to do it.

Yesterday I stopped at Autozone and they had the CRC version...
Freeze Off only $5 a can.

I just tried it on the passenger side exhaust, just as rusty, just as hard to reach and let me tell you...this stuff is awsome...
15 minutes and all three are out...

I will forever have a can of this stuff around.

Hey it's £67.93 over here in the UK - good old UK rip off in action again:

I hope that chills and awful lot of beer.

(Actually I can get it for £6 locally, but that high price was the top line on UK Google).

It's got a place in the workshop for sure but don't expect miracles.

Probably the beer keg sized version - you know, for when a lot of friends stop by

[Hammered]

Ive got a case thats froze up. I may buy a can just to see how well it will do on some for the parts.

No it's just a can or aresol propellant.. Just like the canned air for cleaning computers but they put a dip tube in to shoot liquid propellant.

The liquid boils at room temperature, it's the same process your air conditioner uses for cooling your home.

Canned air.. Flip it upside down.. spray something like a soda can.. Feel the cold

FYI Liquid Nitrogen is -321°f.. That will get your nuts loose

Apparently it works.

I was changing my ignitor yesterday which is mounted on the right side of the battery. One screw was badly stuck and I couldn't get a impact on it without removing lots of parts. Tried tapping the back of the screwdriver with a hammer. No luck. Sprayed it with wd40 and went and had a beer on the back deck. After 20 minutes or so I went and tried the screwdriver and hammer trick again still wouldn't budge.

At that point and time i remembered this thread and dug up an old can of electronic cold spray. Shot about a quarter of the can at it, grabbed the screwdriver applied pressure and tapped it with the hammer. Heard a liitle crack and came right out.

I was so happy I changed the ignitor and had another beer to celebrate.

Both the CRC and the Loctight stuff contain more than just propellent.
The also contain penetrating oil that goes in and does its stuff after the cold works its magic...

For the $5 the can cost me it was well worth it.
I saved a couple of hours of cursin' and sweatin'....
I'm sold...even better than PB Blaster....

[crag antler]

I used it for my broken exhaust studs and no go.
At $12 it was a little higher than PB but as usefull.
Ended up at a machine shop, but it may have just been the studs.
Will have to try it again on easier jobs.

[hikermikem]

I just tried the CRC stuff on one of my broken exhaust bolts - same result as crag antler, no go.

Did seem like cool stuff (pardon the pun).

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 saw a similar product, but not loctite brand, slightly cheaper, and has penetrating oil in the spray already. not sure about the loctite brand, but it may have penetrating oil already.
