No, Henry, you do not have to
No, Henry, you do not have to remove the bonnet. The plastic cover is really a tube runing around the spare tire well, on the radiator side. It covers the wiring harness, and has 4 8mm screws that hold it in place. By taking it out you get another 5 centimeters of space which helps a great deal.
Yes, the fans must come out. The job is really very easy. Removing the hoses is always a challenge - go to the hardware store and purchase the proper tool (looks like a dentist tooth probe). Slide it into the hose-pipe junction and swing it around the entire circumference to break the seal. I use silicone spray to put the hoses back on - it allows easy twisting and movement of the hose on the aluminum pipe.
You will need two people to gently lift the radiator out once separated from the A/C condensor and its mounting points. Take out all of the rubber shock mounts (on top) first. The side rubber shock mounts can stay, but you need to remove the nuts on the upper aspect, leaving the mount attached to the chassis. Or you can take the mount out with the radiator, whichever seems easier. Have fun.
