-- Apply PB Blaster a few times over a week, driving the car in between applications. The bolt heats up some while driving and this will help the PB Blaster soak into the threads.

-- Get the right pulley holding tool offered at places like Ebay and Amazon for around $25-$40. (The one in the denlorstools link above is not the right tool for the 93 Civic DX, though the tips in general look okay.) Use a 5-foot pipe extension on your breaker bar. Use at least a half-inch drive 17 mm socket and extensions. 3/4-inch is preferable but then the tools are much more expensive. I have always had success with 1/2-inch, but there is around 50 degrees of wind-up involved when the bolt is really tight, so be careful as you apply torque with that 5-foot pipe.

-- Attempt to loosen shortly after running the car awhile. This way, the bolt is still hot and should be stretched from heat expansion some, meaning it should be at least a bit easier to free.
