Doesnt that contradict the whole reasoning for taking it off?SeanArc said:m4gunner is right, theres no way the paint would be affected
the insulation under the hood is mainly sound insulation to keep the engine noise down and therefore have a quieter cabbin. it plays only a very small role in insulating engine heat...
well guys i removed it yesterday and theres not that big of a difference, little louder blow off sound (i have the opti-flow intake)

I don't know the temps for the fans, but I would guess they come on at 180 deg F or so.
The cooling system factory thermostat is probably about 195 deg F. You can't go too cold. Keeping things pretty hot helps fuel economy. Also, if you run a 'stat too cold the ECM may never run in closed loop, it will always think the car is still warming up. Aftermarket thermostats often come in 160 and 180. 160 will most likely be too cold.

i was just saying that people in the other forums were taking it off for cooling reasons which is contradictory
You are correct.EarthDweller said:Are these readily available as part replacements for our cars?
For it to work, the new lower temp thermostat would work effectively only if the electric fan cuts in earlier. Im not sure whether that is controlled by the ECU thru a sensor. Most other cars have a mechancal/eclectrical fan switch which can be changed out to a different value.
