My '09 Ranger, with the 4.0, seems (based on very preliminary diagnosis) to have a t-stat sticking open...always used to run just below mid-scale on the gauge. Starting yesterday, it climbs maybe a quarter of the way up; a little higher if I'm on the hammer climbing a long steep grade.
I have vague recollections of a conversation with Bill awhile ago about t-stat housings, gaskets, and o-rings...but hanged if I can remember any of the details.
So...assuming I determine it is the thermostat...what parts should I buy beyond the t-stat itself? Guessing I need an o-ring, can't remember if this is one of those engines where you might as well just order the housing while you're at it, or not?
Thanks!
