Hey, Ive have experienced the same problem before. Your thermostat is too cold. The way it works is simple. With a cold thermostat, its gonna open early, letting cold water back into the block. I think that the radiator is cooling the water too much, hence cold temps. The problem can actually go to the opposite extremety too. If you put a good load on the engine and run the hell out of it, you'll more than likely over heat. This is also caused by too cold of a thermostat. The water was not staying in the radiator long enough to cool enough before the thermosat opend again, causing overheating. I just had to experiment with mine until i found the "happy-medium" to make it work correctly. I think it was a 190, but every set-up will behave a little differently. Cooling systems sound easy, but thats not always the case. Hope my similar experience helped. Good luck buddy.
