This is a tricky one and a knuckle buster!

The AC coil bolts onto the radiator assembly with 3 bolts on the top, you are correct about that, but the lower part actually just "sits" into 3 mounts mounts on the radiator. You have to disconnect the A/C line bracket on the lower part of the chassis (not disconnect the line) on the drivers side right where it goes into the condenser. Once you remove this bracket it gives you enough slack to pull the etire assembly up (fans, condenser, radiator) when you pull it 2-3 inches up you can then move it back toward the engine and then lower past the crossover that the radiator sits on, from there you can slide the condenser and radiator assembly up and then the radiator will become detached. Slide the radiator to the floor, move the condenser and fan unit towards the front back into it's original position and then you should be able to move your radiator out of the car. Good luck!
