I started changing my timing belt but got stuck at the crankshaft pulley bolt. Neither of my impact guns could get it off. I tried turning the compressor pressure up to 125 psi and still nothing. So I took off the starter and put a big screwdriver in the flywheel teeth. I still couldn't get it to budge with a breaker bar so I put a 4 foot pipe over it and tried again. My 1/2" extension snapped. That extension and my impact gun have gotten a lot of tough bolts off and haven't failed me ever. So I know it's not just my tools. I don't have cheap tools either.
What else can I do? I was gonna stop by a few shops to see if they have a stronger gun but most of them were already closed so I'm stuck for now.
Rent this tool. Youll NEED this tool unless you have the world strongest compressor ever.
You put in inside of the crank, and you put a half inch ratchet on it to hold it. Then with another half inch breaker bar, you break the bolt loose.
When I was stuck on that bolt I tried everything from drowning it PB blaster, putting a torch to it, 3 different compressors and nothing. Once I got that tool from Pep Boys, I had it off in under 2 minutes.

Then my mom got a chevy malibu. This was about 10 years ago, when they had notorious IM leaks. To change an IM gasket in a gm, it literally is easier to just pull the engine out the car.
Took me damn near 2 full days to change the gasket, and I had a cousin helping that was a ASE. We had to take so many things apart, just to get to the IM gasket.
Then 2 months later, it was all over again because the timing chain needed changing.
The next day, she traded it in on an accord. Never again will I wrench on a gm.
I agree that the crank bolt pulley is a bitch *til you have the tool/good air tools* however you can still bring it to a shop, pay 5, have them back it off for you, and go home and change your timing belt in a good 3 hours. Then have another 6 years of driving headache free. On american cars, you are lucky to get 6 years driving without changing the whole motor. In hondas you swap the motors because you desire more power, then some kid buys your old motor, beats on it for 5 years, and it still runs. Not so much on the americans. My buddy has a ford lighting and we always joke that the 5.4 engine is a "wear item" since he's on his 4th motor in 3 years , lol.
