my temp gauge is the stock in dash one and i was wondering about where 210 should be on it, as of late my car has been getting hot to the "R" and "M" area wich is abnormal, but i noticed this after i had it dyno'd. At first I thought my tuner might've changed the fan settings but he said the high speed comes on at 210 and it is coming on. Second thought is that i was only running a little bit of coolant mixed with distilled water and a bottle of water wetter, maybe i've boiled off all my water and i just went outside pulled the cap on the radiator and ran the car to operating temperature and every time it cycled i filled up the radiator with a premix of 50/50 coolant and let the bubbles quit bubbling. I dunno what it could be, i don't see coolant in the oil nor do i see/smell it in the exhaust or see it on the plugs.
