So I'm stuck at a stand still changing the water pump on my 07 wrx. As of now I have the radiator and surrounding parts off the vehicle, fluids drained ect ect. Now the harmonic balancer will not come off. The bolt will not budge at all. I have tried my 1/2in impact gun, Breaker bars, all while holding the pulley still. The bolt will just not move. I've applied heat, lots of force, and my few most trusted mechanics here to help.
