This job must be done from the inside. Remove the glove box door, remove the blower and wire harness, remove all the little screws that hold the heater box, now from the engine compartment, drain the antifreeze from the rad, you don't have to drain it completely, remove the 2 heater hoses that go to the heater core, check for 1 or 2 small screws also on this side, back to the inside, remove the cable for the heater control on the box, now you are ready to remove the heater box, and the core is hiding in there. All in all, you have your next couple of hours planned. When you have the job done all the parts back in place, ready to start the engine, just add about half of the antifreeze that you took out, let the engine build up to operating temp. with the heater open, and this will let all the air out of the lines. As the thermostate opens and the fluid circulates, start to top up the rad. Good luck.
