I am having the same thing happen to my Wolfie; last Sunday I went to an art fair here in Asheville. When I got out of the van, I noticed the same thing.....the wolf was peeing all over the parking lot. There was plenty of coolant in the pot and I couldn't find anything wrong at first. When I opened the engine hatch, it was coming from a crack in the double "T" between the overflow pot and the radiator pot; ordered a new double "T" from Ron at Bus Depot. I don't know if this'll help, but I found the cause of the leak and hope it helps others. I had been driving in some stop-and-go traffic before parking.

  .....my Vanagon pees coolant, the good German kind, all over the tarmac.  The overflow bottle, well, overflows.  Drive around town or at lesser speeds and it's OK.
