Well back from a 4 day trip and the weather was nice in the 65-70* range when pulling the hills so there was little chance of a good test to see if the work I did helped.
my head as now after putting in a 180* thermostat (That has no temp stamp on it) the engine temp is running at 200* and while pulling hills it got up to 210* and went right back to 200* once the hill was cleared.
Best I can figure is they gave me a 200* thermostat because even if it idled for 15 minutes the temp wouldn't drop below 200* +/- 3-4*.
So things seem to be better but back to the drawing board or another Thermostat to see what the heck is going on.
I may flush the Rad again just to be sure it's clean but the first step is to swap out the thermostat.
