Bill==You are right on the timing----as I recall. Not to call out any OE's, but Chrysler products, expecially Dodge trucks during the early to mid 2000's were notorious for heater core leaks. Yep---major surgery in the cabin to R&R them-along with the evacutating the A/C system. You could look into the inlet/exit tubes and see the aluminum pitting from the Dexcool. Similar with the 'plastic' tanks. We may be seeing something similar here.
