I saw a Vanagon with a For Sale sign on the windshield so I stopped and took a look.  It was an '82 Diesel and the lady at the house was selling it for her brother who is in the Persian Gulf somewhere.  She said it hadn't run in a long time - bad transmission.  While looking in the engine compartment, I noticed that the coolant hose that came off the front of the block and went forward to the radiator was cut about six inches from the block and a brass T with a male garden hose connection was inserted inline.  There was a brass cap on the hose connection.  In the storage area under the back seat was a six foot piece of garden hose with female connections on both ends.
        This must be a way to either fill or flush the cooling system but I can't figure exactly how it would work.  Any ideas?
