How to loosen a difficult crankshaft pulley harmonic balancer bolt. The first method uses the power of the starter motor, and the second method uses the force of the rolling vehicle. Be sure to disconnect the main coil wire before attempting, because you DO NOT want the car to start when doing this! This was done on a Ford Taurus but should work on many vehicles. The rolling method only works on cars with a manual transmission. Both methods work best on front wheel drive cars.
