Good luck with that, it's part of the coolant overflow and they all break that damn hook off on the front of it. Is this what happened to you? If so I have a simpler fix if you're interested.
I'll supply the garden hose to feed the solenoid, and I guess you'd better get a nitrous filling station to hook up direct. As soon as I get another truck we can spray the iron duke in my S10, wanna try it?
Depending on how you're feeling, the best thing for me is to take it easy a couple days and then just start using it again. Sometimes just getting moving makes the biggest difference.
