Hi guys. Was out driving the vette after 9 months off the road. I was doing mainly highway driving and the engine temp was getting up to about 260f, the coolant temp was staying at about 200f. When I got to where I was going I popped the hood expecting the electric fan to be running but it wasn't. From what I gather it should come on at 230f, but is that the engine oil temp or coolant temp? I would have thought it's engine oil temp. Am I right? If so I need a new thermostat. (Fan does run if thermostat is shorted)
