THANKS Tom!
We replaced the thermostat at same time new fan clutch etc...OEM of course.
Ironically, I just bought a SG2, but it hasn't arrived yet. I decided I want to know the engine temp/coolant temp, and we want to know how the tranny is handling towing on our other truck. (It claims to come with a tranny cooler, standard). Oh heck, who am I foolin', I just wanted one to play with and learn all kinds of new useless info!
I'm running out of 100+ degree days, so I decided to try it now anyway.
