Ok i bought a Stant Superstat 65869. This is my first t-stat replacment i have done the old t-stat didn't even have a jiggle valve but i am having trouble getting it back in what is the best way to do it put the o ring in first then the t-stat or put the o ring aroudn the t-stat and then put em both in at same time? I will go back and work on it but was just wanting some input thanks.
