Was wondering if anyone has thought of a way to get an alarm to sound or light to light before the factory light turns on, possibly before the engine overheats and warps the heads and causes major engine damage?

 

Its called keeping an eye on your guages.

 

The gauge never moves so one tends not to look at it. I've seen my temp go from 190 to 204.8 degrees (using an obd2 reader) with no change in the needle. At what temp will the needle start to move? And will it be too late if you're not staring at it like some geniuses on this forum? My cousin had his fx35 overheat and he had intermittent overheating issues after that caused him to go crazy and eventually get rid of the car he loved so much. Im just trying to be proactive..
