Codes
Okay. John Deere had some radiator problems around 2005 and they've been replacing radiators. If you purchased this new, your warranty has run out. I would contact Superior Diesel in Rhinelander, WI. Superior Diesel is the company who supplied Vermeer with the engine. The codes you're getting are relative to John Deere and not Vermeer. You can contact the service department at 888-803-9175.
Hope this helps.
