I'm wanting to do a coolant drain and fill on my 85 and was wondering if there is a latest and greatest method for  one man (along with reluctant wife) to do a drain and fill without jacking up van and runnng front to back to open and close valves or drains. I would take it to a service shop but don't know who can service a Vangon here in the Chicago area. Thanks for any help.
