Does the fan turn on at 3/4 right before the red (like GM designs their cars), or is it supposed to keep temperatures steadily at 1/2?
Heh! Let me tell you about Honda CiViC temp gauges...
Basically, they're glorified 'idiot lights' by design.
If you ever see your gauge go past 1/2 way, there's something seriously wrong with your car 'cause it'll take the fires of hell to make it move past that point.
The way it works is - 'C' at cold start up - 1/2 ALL the rest of the time. If it goes past 1/2 you got a cracked head, blown head gasket, exploded radiator hose, tossed belt, et cetera.
Bottom line: if you wanna see what's going on, you'll need to buy a REAL (accessory) temp gauge...
