The OP wants to make his car run 180 or less at idle. It's certainly possible to do that with the right combination of parts and tune. Why is everybody trying to convince him to let his engine run hotter? So what if you can. He doesn't want to.
I think everyone is trying to convince him it's OK to run a bit hotter. He's convinced everyone is wrong. He's also convinced that all the suggestions made so far are wrong. I'm convinced there's no solution to his perceived problem. He's attempting to fix a problem that doesn't exist.
"He's convinced everyone is wrong." This is one problem with people today who have a deficiency in reading comprehension. Where did I reject suggestions except it's fine to run an old motor at 220 plus degree's. New cars with redesigned systems run fine at 220 plus. Old iron was not designed for that. As stated earlier if My Dodge goes over 210 the stock gauge would be pegged..hence it's trying to show the car is far out of it's "safe" operating temp and action is advised...like a "check engine"or " overheat" lite for all the youngsters.
Anyone who cares to run an old engine at 210 plus "all day" is fine with Me as I know what the end results will be. I am trying to run My Dodge at manufacturer recommended specs.
