Remove the bolts on the front two "dogbones" (engine mounts) and with the vehicle in park, roll the vehicle forward to rotate the engine towards the radiator. Not too far that you cause damage to the delicate radiator fins. This will provide more space behind the motor to access the back three plugs.
Hope this helps.
