My gauge i was reading that my engine temperature was normal wen it was not the my camaro was running with no water and the gauge was reading normal how can i go about that.

 

The sending unit for the temp gage needs to be immersed in coolant in order to know what the coolant temp is. Since you let the engine run out of coolant, the sending unit had no idea wht the temp was. What it was showing was the temp of the air inside the water jacket.

 

The probe on the sending unit needs to be submerged, as it reads coolant temperature, not air temperature.
You need to find out why your coolant level is too low. Do you have a leak (internal or external), or is it just from lack of maintenance?

 

i had not been checking my water level on the radiator because it was reading normal but the funny thing is that when the temperature in my area dropped the temp of my car was still reading normal. the other thing is that the gauge needle never moves from the same position and thats why im wondering if the gauge is not reading correctly

 

So you're saying the needle never moves, is that even with the key off? The gauge is bad then, if that's the case.

 

yup not even with the key turned off i was afraid of that so is there any way to fix that though
