Thanks Gilly......I'm no mechanic...but as with everything I own...I prefer to learn and understand how and why things work or don't work.
I really dont like paying someone to fix problems for me, especially after seeing the kind of work some so called professionals do. I built my home 40 years ago and have done all the maintenance, including plumbing and electrical. I work with "so called" pros everyday and can tell you I dont want them working on my house.
Read a few more articles about outboard thermostats, and at least I'm getting a better understanding, and that apparently a constantly open one can cool the engine too much, and cause unburned fuel problems and carbon buildup, especially at low speeds.
