Air impact wrenches can provide significant force to remove rusted exhaust nuts. However, heating a flywheel ring gear until it is red hot is not recommended as it can cause the gear to warp or crack. Instead, the ring gear should be heated to a temperature of around 450-500°F and pressed onto the flywheel with a ring gear installer tool.
