2003 Ford Mustang FLY WHEEL

I don't think you are correct with righty, tighty and lefty, loosey. On the flywheel it is stamped counter clockwise to tighten. There is about 3 inches clearance between the nut and the electric fan for the radiator. There is no way to get an impact wrench in therer. Any other ideas?

My bad, I am not using the correct name apparently. It is the wheel on the front of the engine with the belts that run around it. I have always referred to this as a flywheel, but understand you are correct. We are trying to remove this wheen in order to put a larger wheel to boost the rpm of the super charger. All of this being done with the engine in the car.

Yes, this is a 4.6 Cobra Mustang 50 year anniversary special. The 14mm hex is the size tool that was sent with the booster kit to remove the center bolt. Also a puller was sent to remove the pulley once we get the bolt removed. It is the bolt that we are having trouble breaking loose. The center bolt is made like an allen bolt. That is what the 14mm is aobut.

Thanks, we are turning in a clockwise direction but cannot break loose. Was trying to avoid pulling the radiator but that may be the only solution. Just looking for the easy way out.
