"Swing Out" Radiator to Flush from the Back

I brought my coach to the Cat dealer to check the radiator fluid and flush as needed. I have a 2004 Cat C7 that has not has much maintenance until I purchased it last year. It has a rear radiator. I have been doing Simple Green flushing from the rear since I cannot get to the other side. The Cat fellow said he "swung out the radiator" to flush it from the inside and it was in very bad shape. Obviously, my Simple Green from the back cleaning was not doing any good.

First question: How do you "swing out the radiator"? Is this something I should even consider doing myself?

Second question: He said to take it to a high pressure car wash once per year and flush from the back with hot water. He said to be sure and point the muzzle straight on so the fins are not damaged. Has anyone done this? Can I purchase a pressure washer to do this? He said it takes a lot of pressure to go all the way to where the gunk builds up.

#1..."He Lied". I have never seen a radiator set up on Hinges so that you can "Swing them out" from their original position. If you can find some sort of hinge mechanism, let us know.....PLEASE

#2... YES you can purchase a High Pressure washer that will work for this purpose. Better yet, wash it from the engine side of the radiator. Simple green works fine. If you have two radiator assemblies spaced approx. 1" apart, it makes the job harder...
