BFH = Big F@cking Hammer

A rubber mallet is going to obsorb the blow when you hit the wrench. A metal hammer will send a vibrating shock threw the wrench to the fan nut which helps loosen it. Its kind of the same principle as a impact gun. The rapid hits work better than a constant force for trying to loosen a bolt or nut.

 

so i should hit it as fast as a can with reasonable force rather than trying to smack the hell out of it, got it

 

just hit it like I said earlier^ fast and hard... your not pounding anything it just has to be fast so the pulley won't turn. As said by Zick the mallet will absorb the blow, use a hammer and knock it quick. I've done it a million times to many trucks. Also the PB Blaster isn't neccessary.

 

I'd lose the crecent wrench (I assume you mean adjustable wrench as Crecent is just a brand name for their line of tools) as they tend to strip fasteners REAL easy. Get the right 6 point box end wrench on there and it will not only resist stripping better, but will transfer more of the hammer shock to the fastener as well.

 

what are you talking about? you can't put a box end wrench on the fan nut.

 

you could use a air hammer just hit the edge of the nut moving it left.

 

Yup, seen that done before too.

 

yea well im not looking to invest 100$ in air compressor tools and stuff so ill just stick with what z06 mentioned...i think im gonna go try it now actually

 

well i got out there ands started hitting it and it just didnt seem to go over very well being i live in suburbia and didnt want to wake up the neighborhood association and get a dirty letter so it will wait for the morning!!

 

i just put an air chistle on mine,it knocked it loose in a split second.
