The radiator will come out from below, and IF you have never taken the cowl off this may be the fastest method, but don't underestimate just how much height you need to be able to drop the radiator down below the car.
You also need a helper to catch it as you free its passage past the various obstructions (mainly the valences , the bottom "tray", the tie bar and the radiator mounting brackets)
If you have previously taken the cowl off and replaced the fasteners with quick release versions , it will probably be easier , and faster to take it out from above , and it can be done single handed this way.
