The procedure is done from underneath the car, it is not a big deal but could turn into a PITA. example - last time i tried it, i busted the a/c condenser. so if you do not want that to happen and you do not feel like opening your a/c system and loosing your freon, cut a cartboard and stick it between the radiator and the condenser. then unhook the wires from the fans and take it down together
