I believe you have a crossflow radiator from 1985 up, so the front end doesn't have to jacked up nearly so high as with the older vertical radiator. You can unbolt the AC condenser and/or external engine/transmission oil coolers, so you shouldn't have to reservice the AC. On the back side of the radiator, you will also need to unbolt the radiator fan shroud and the fan and disconnect the transmission and oil cooler lines from the radiator tanks, and then unbolt the radiator, which should slide right out the bottom just forward of the crossmember.
TIP: While you have the coolant drained, it would be a good idea to check to decide whether you should replace the water pump at least change the little rubber bypass hose between the back of the water pump and the front of the intake manifold.
