I already asked a question about the cooling system but I am pretty sure it is in my cluster. The temperature gauge works fine most of the time and my car doesn't over heat and is at the correct level. I am wondering if the guage has a malfuntion will the message center still tell me the engine is over heating. For instance if the gauge is reading 140 but the temperature is really approaching over heating will I still get the warning. I could honestly care less about fixing the gauge as long as the warning center will still function. I usually let my gas get low just to make sur ethe warning center works for that and it does I would NOT want to test the cooling system like that.
