The car is leaking coolant from the passenger side, in front of the passenger side wheel. And my passenger side floorboard is wet. It's my opinion, that the heatercore is leaking.

give me insight, on how to remove and replace the heater core in the car.

Are you sure it is the heater core? Do you have overheating and coolant losses issues? A bad heater core would result in that.

It could just be a clogged drain hose from the A/C cooling coil.
