Upper front bushings

Outlander x 800 g2. Changed all bushings except for the upper front. I see I need to move the radiator for clearance to pull the upper a-arm bolts. Any tricks or tips for doing this would be appreciated. For instance do I need to completely disconnect the radiator or simply take off the bottom radiator bolts? I have a service manual but no specifics on this step.

Thank you!
