I didn't realize the tool was in the end till I quit for the day. The Winnie manual said I should use a 1/4 nut runner. When that didn't fit I figured I still had not found the right area, so I quit and took both manuals back in the house for another read (Was 98% frozen by that point anyway). The HWH manual talks about T handles mostly, but in one place does mention the tool in the cap. I will try it over the weekend. I think I have a leak in a T fitting. the whole area is covered in fluid, but that T seems to be source. Not sure if low fluid would cause the creep out however. Or maybe the leak is causing it to lose pressure over time. Not sure if pressure it was is supposed to keep it in however.
Going to be even colder this weekend, so it's not going to be fun
Thanks for all the help
