Just did my coolant yesterday for the first time on a L-3800. I followed the book and just drained about a gallon from the radiator only. I then added distilled water and a radiator cleaner that will run for a few days before I change it out with the 50/50.
It was easy to dump the recovery tank.
I too was concerned about not getting all the coolant out but I think now it's going to be just fine.
