I am still not sure how to flush out between the CAC and engine radiator. The outside one (CAC & Trans cooler) is reachable, the inside one (Engine Radiator) is not and the issue is between the two.

I have only owned the coach for a year and only drove it once in salt, in January of this year going to Florida. I did thoroughly clean the coach and flush the radiator when we arrived there. The previous owner lived in Dallas Texas and kept it in an airplane hanger and used it in the summer months for vacation trips. So no real exposure to salt and it has no rust / corrosion underneath or anywhere else. Flushing with water would clean the outside of the CAC but not the radiator or in between the two, which I think is the source of the real problem. There are many of these coaches still in use. I don't think I am the only one to have this problem.

I am having a similar problem with my 2000 Country Coach Intrigue with ISC 8.3 Cummins (350hp) / side radiator with 82000mi. The transmission cooler began to leak and when the shop removed the CAC and Trans Cooler (1 unit) and is mounted in front of the engine radiator. We found between the two was a mess of debris that was probably the cause of the trans cooler failure. The engine radiator was also full of debris and the core is rotting. I believe the debris was the cause of the trans cooler failure. Also, I don't see a way to clean out this area to prevent future problems after reconditioned. Any advise as to cleaning the radiators and in between them in the future. Hopefully without disassembly? Any help as to what this repair should cost, with reconditioned CAC, trans cooler reconditioned with new core and engine radiator reconditioned with new core? Input / advice appreciated.
