Yes, there is a hose fitting bolted to the head. There is also some kind of repair "goo" all around that area so I'm not real excited about removing it. It would be great to find some type of in-line fitting to put in the radiator hoses. I was also worried about lack of flow. I wasn't sure if the regulator was going bad or not but I thought the freezing and thawing surely had to effect the diaframs inside it. I think I can buy a new one with water ports cheaper than rebuilding this one.
