I have a 180 Thermostat and my operating temperature is usually right around 185-190. I would assume that the thermostat is doing what it is supposed to, but like Dan said, the fans will still kick on at the normal temperature. I had to have my PCM programmed for 185F fan turn on. Otherwise even though the coolant is flowing, the fans wouldn't be cooling it off. The same would go if the fans did come on at 185, but the thermostat didn't let the coolant flow till it got hotter. Both are needed to cool the engine. Am I right guys?
