techniques for loosening that big giant cooling fan nut

[indigoth]

so, my fan belt is pretty loose. I really should adjust it before it leaps off the pulley somewhere. that big nut is mondo tight. I had a 4 foot breaker bar on it and couldn't budge it. I had some trouble holding the pin wrench in place while i was fighting with it. I don't have an impact wrench, nor am I able to get one in the near future.

any tips/clever ideas?

Thanks

Jim

Mine was also mondo tight...took two of us. One to hold the stock pin wrench (while on the driver side) I had to stand on it, and the other
to turn the nut with a breaker bar. My friend had a very interesting tool that went on the square end of the bar and multiplied
the force. I have not seen one before or since, been looking though.

I think this might be what you're looking for:

I saw one used once and was very impressed but couldn't convince myself I'd use it often enough. Of course that hasn't stopped me before when buying tools

I've discovered that normal driving does the job. I hope none of the cars behind us on the M6 got hit by the bits

Robin,

Did your fan blow up? I'm assuming so, from your reference to "bits". Pretty dramatic when it happens.

I found a piece embedded in, and nearly through, my engine cover. I ended up pulling the top tin off the motor, and found parts jammed into the cooling fins.

I can't help remembering the incident every time I run an engine with the cover removed. A blast shield would be a wise idea for such an application.

No, fan is OK. It's the nut, pulley half & spacers I've lost. Writing this from the passenger seat if an AA flatbed
