Default Help - can't get these nuts off

I may have screwed myself here... can't get these 4 12mm nuts to bust free. Well I got one off, but two of them are now pretty rounded, and the other won't move. The belt isn't turning, the pulley just spins inside the belt when I try to move them. Too tight with the fan to put a socket on them, and my open end wrenches have now rounded them off.. what to do?

I just picked up a 10 - 12 mm flare wrench at sears last week. Worked great on those rounded off brake line nuts. I took a flat file to the nuts to reshape them some first. How I ever managed without that tool before, I don't know.

Well I tried the flare wrench, now I have 3 more round nuts. that thing was useless. At least I got one off so I can take that to the store tomorrow, but I'm going to switch to the grinder now.

I'd be careful about the grinder Tim. I would hate for you to go to far and mess of the bolts.

A short socket with the (can't remember the name ??) kind of socket wrench with the bend at the end won't fit?

what about trying heat to break it free. I had to do that on my 40, err your 40 when I removed the original springs.

These things are tight enough to round off in the flare wrench... and I don't think I have a vice grip that will grab that tight anyway. I tried heating one with propane, didn't seem to do anything. Plus I can't get the grinder in there anyway, it smacks into the pulley before the wheel will even hit a nut. So now I'm filing my way through each nut.. damn this sucks.

Try a larger vise grip, you may have to get a new one that fits they have several sizes and shapes. If that does not work try a Rotozip style tool with a small grinding wheel. If that still does not work and your truck still drives you can come over to my house and we can use the plasma cutter. It may take a nick out of the pulley but I have gotten pretty good with it.
