I originally posted about the squeezing of the radiator hose untill the sloshing noise stops. Here's an update. It's Been a month now, we have had weather from the 70's to 16 degrees. Not once did it go above 205. Heater worked every time. I'm gonna stand behind the squeez and listen method. I also did a few 1/4 mile runs back to back and temps were below 200.
