I use an electric sprayer they do not have as much pressure, but do an excellent job of cleaning from the front to the rear. I crawl under the rear of the coach on the passenger side.

Give it a good spraying with the Simple Green which would be on the front of the CAC. Then go to the rear of the coach and spray the radiator with Simple Green also. Let it soak for about ten minutes, THEN use a nozzle that does not spray hard and flush from the inside out. Then do the same from the rear of the coach for the radiator. Flush it real good with water. Then start your engine and the fan will blow every bid of water that is left out. I have been doing this at least once a year for the last ten years and my coach does not over heat.
