Default Stock coolant temp sensor

We all know the stock temp guage doesn't move around much. However, does the stock coolant temp sensor output a wide range signal, that could be read for a guage or something?

I'm thinking about making a little relay type thing that will light up, or buzz to let me know when the engine is running too hot.

I echo the above statements. Find room for another gauge. You can get digital readout temp gauges from somewhere if that fits your scheme easier. As for the signal I have my old CTS sitting around somewhere. I could possibly check the resistance on it. Otherwise you'll know your car is running too hot when your fan is on constantly. You could always piggyback a light or something onto that relay so you know when your fan is running.

Ok, here's my exact plan. I found a little device you can build for around $10 that will trigger when it reaches a certain voltage. I am going to connect it to the coolant temp sensor, and program it to go off when the temp gets into the "too hot" stages. I'm then going to hook it up to either a buzzer, or a light that would go off, so I could hear/see if I was overheating much more quickly.

I would like to get the guage, but there's no room currently, and I can't watch the guage all the time when I'm driving hard. The light/buzzer would get my attention if there's something wrong. (Same premise as a shift light)

I was planning on connecting one to my EGT guage as well.
