Thank you Joel and Gerald for your responses.
I haven't had the opportunity to change out my hose and coolant, as the hose didn't make the truck., and now is not forecast to be here before Tuesday. That said I have been reconsidering possibily taking the coach to one of the truck repair outfits, Peterbilt is close, or even over to Cummins Northwest in Spokane. My main concern however, is that the hose is disconnected from the bottom of the expansion tank. So, my thought is to plug the hose, secure the clamp to hold the plug in place, then make the drive to whichever location I am able to get into. That would simplyfy my having to try and do the job in what is basicly a large pasture, with no running water or proper place to dispose of the old coolant. I may have one other small delema since I disconnected the two "return lines" that come from near the top of the thermostat housing, into the top of the expansion tank. I would not expect any overheating due to lose of coolant in a short 10 to 40 mile drive, however, should/could I expect coolant to be pumped up thru those two small return lines?
Thanks for any info, thoughts or suggestions.
