Well, I threw in the new thermostat last night. Its still getting up to 200F on country roads (45 mph). That means on the freeway (65 mph) its going to overheat.
I did notice that if I shifted to neutral and revved it, it seemed to drop the temperature. Also, when I got home I felt the lower radiator hose and it wasn't very warm where the top one was scorching hot. So, I'm obviously still not getting much flow through the radiator. My guess now is either a bum water pump, or a plugged radiator.
Does anyone have any ideas on how to test out what to replace/flush?
