Many more manufacturers besides CC were impacted by this radiator supplier. CC is for sure not the largest builder impacted
If you can attach a magnet to the side caps, and or if you see bolts where the side caps attach, then you have a non problem radiator. (Going from memory on this one, but that is how I think it was explained to me...).
Top three things to be aware of, of which the third is mostly cosmetic:
1) The radiator problem mentioned. Coach specific, as CC had other radiator suppliers and it was the luck of the draw as to which one went into which unit. (For sure on 2004 Allure models with ISL's. Can't say this is for sure on others and all years.)
2) Dry Power Take Offs (PTO's). Requires a wet kit mod, or plenty of maintenance and inspection to grease gears if not changing over with the wet kit.
3) Micro Checking - As I recall, the higher end Magna's and above were not impacted(?) as they used a different supplier of glass for the sidewall construction. Allures, Inspires and Tributes are the models that may be impacted. Usually more of a problem with darker paints.
I'll also add that when looking at other models, learn the specifics of what gremlins may be involved with them. As most models have a areas that may need addressing. Understanding what to look for, and if not already taken care of by a previous owner - negotiate accordingly.
Have fun, be safe,
