B2500(ford ranger motor)?
I did remove the radiator and used a air wrench still wont break loose

PB Blast it a couple of times for a few days. Let it really soak in.


You can always try heat also, just be careful as there are fuel lines right above you.

I've done the big breaker bar and crank method as well. Dont hold the key and try to start it, just click it over until you hear it try to turn, then back off the key. I watched an idiot start his car with a breaker bar on the pulley...the socket did not want to come off and it beat the living crap out of a bunch of things. All you want to do is break it loose and remove it by hand after that.

Use a 1/2" 6 point socket for the bolt,and a breaker bar,put agaisnt anything solid so not to damage anything.Crank the engine.it is unconventional but it works.

with an air wrench you can't do it

you need a 1/2 inch air impact gun or if the truck is manual trans, put into gear put the brake pedal to the limit and with a 1/2 handle with an extention pull it hard, it have to break or loose
