when I had mine out I used a hot water pressure washer and injected simple green with it through the washer.With the radiator out I washed from the back forward,that be like washing it in the moho from the back to the front of the moho just to see if I could wash though and it did the job.With a regular washing it would not be hard to keep up.
Scott....not sure if yours is the same as mine but the big ring that mounts on the engine with a bracket on top and bottom stays on the motor the shroud has a rubber seal that slips over that so the shroud comes out with the radiator, had I known that it would have been easier to pull the radiator
Scott....I had to pull my Radiator on mine to fix a failed fan bearing it took me about 5 hours to pull it by myself.
Not sure how yours is but it was not bad at all.
While I was at it I powder coated a lot of the brackets and some painting as they were pretty rusted from the Texas winters I drove though and also gave the inner cooler and radiator a good bath with a hot water pressure washer and simple green.
I also found some lines and top radiator hose that needed to be rerouted as they were rubbing metal.
Also changed all the hoses and belts.
I also added a electric controlled fan drive that really helped on mileage and power.
here's a couple of pics
