Apparently thermostat temp ratings are a touchy subject on other forums so let's see if yous guys are better mannered! I'm wondering if there is a scientific reason to with one temperature thermostat versus another; an example being 165* vs 195*. I have looked at (and posted on) some other forums and this question really turned into a s##t storm with no real answer. I need to replace my thermostat but every parts store lists a different one for my truck and everyone I talk to about it has a different opinion on which one is the right choice. Also, I live in the colder end of Michigan and I don't know how or if climate should effect my thermostat choice.
The truck in question is my 1985 F150 with a carbureted 300ci straight 6. The truck is used for commuting durring the week and towing 5,000 pounds of either tractor or sled dogs on the weekends.
Thank goodness my Deere runs of a thermo-siphon system and doesn't have one!
