Thanks display-name, I didn't notice any high point orifices to fill the radiator like you usually find in systems, only the overflow tank. I think it's time to study the service manual. I don't have a hard copy, so it's kind of a pain in the ***. If you found a fill point I'd appreciate a post. Thanks MM
