Step 1.
Whack the bolt head a few times with a hammer. This helps break the corrosion bond and reduce the torque needed to get the bolt loose.
My brother lost the timing belt on his Integra, but did not bend any valves, passed a pressure test. We borrowed my buddies Snap on Impact and it would not touch it. A breaker bar and piece of pipe did the job. the break off torque was at least 3 times the spec.
I once used the weight of the car to break a badly rusted rear axle bolt loose on a Z car.
Long pry bar between the lugs and axle flange, six point impact socket with, breaker bar and pipe. One sticking out the back, the other out the front, lower car lift down almost until that corner started to come up off the lift arm!!!!!
It finally popped and no I did not forget to unstake the nut.
