It's actually very easy. We took the bolts off the coolant reservoir and moved it out of the way, then took the alternator off because it was in the way. Iirc, that was the only extra work required. Once those two things are out of the way the pump is pretty accessible. You may need to remove your passenger side wheel for easier access to the bottom bolts, and I recommend either getting Gates or Dorman metal coolant pipes to replace the plastic ones while you're swapping the pump.
