-27 a couple of nights ago and no more leak.IMO NO way it should require that much.
Call Wix and asked if anyone else had this issue or if the changed the specs of the rubber gasket. They said no to both.
Once again just an issue when really cold. When It is warm out the hand tight works.
Oh well, just have to remember when I use to ask how tight he wanted something on a car.
"As tight as you can and 3 more turns."
