I want to change the coolant in my 330 ISC, I think I could do it my self the book says something about getting the air out, this is something I am not sure about. Any instruction would be appricated. What would be the estimate on a dealer doing this, I don't have my book with me at this time so I don't know the Capicaty. Thanks Roy

My Country Coach owner's manual includes a very detailed procedure for changing the coolant in our ISC engine. The manual isn't in front of me now, but it includes draining, flushing with water, flushing with a chemical (can't remember what), then flushing with water again, then filling with coolant.
I didn't want to take it on myself because I didn't have any reasonable way to dispose of all the stuff being flushed out of the engine.
Instead, I went to a nearby dealer, and had them do the flushing procedure, and then fill the cooling system with an extended service interval coolant.
Now we test once a year, and haven't had to do a complete replacement yet.
