I can take a picture if needed. But basically the bolt just won’t turn no matter what I try. I even tried with an impact drill and nothing works. The bolt doesn’t have any rust or oil on it so I have no idea why it’s just so stuck. Any advice? Anything I’m missing? Also sorry, fairly new to cars and home repairs so forgive me if I missed any vital info. Doing this from my phone in the sun so hard to see. Thanks! Also, I’m just using the words that the guy at autozone told me. I have no idea what Everything is called, I only know how to fix it. ---

Would you narrow own the “bolt” in question? Is it the crankshaft harmonic balancer bolt? I think the torque spec on that is only 79 ft-lbs but the bolt likely has LocTite or other thread lock compound on it. A 1/2 inch air operated impact wrench will usually spin them off after a bit of trigger-action. Or a long breaker bar, or maybe one with a pipe on it. It is tough to get it to break free. Dumb question - you are turning it counterclockwise right? ---

It may require an impact gun to remove the bolt. ![](https://global.discourse-cdn.com/cartalk/original/2X/f/ff2a3105506b27432e652b60793e2a60515b76fc.jpeg) Tester ---

Yeah that’s the bolt exactly! And yes turning it counter-clockwise. So just keep trying basically and maybe get an impact wrench? Just wanted to make sure it was ridiculously hard to get out and nothing that I missed. Heard it was a tough one to get out but never knew it would be this tough. ---

Why are you taking it off? ---

Again don’t know the exact words for every thing so bear with me. The rubber holding the part that holds the belt on went bad and fell off so I need to replace the whole piece. ---

Yep, that’s the ‘harmonic balancer’. Just wondered, not a commonly-needed repair.
