What? Why? How?
I don't have schematics right now, but I can't remember seeing it on there. If I have to try to start the car for three times, it will probaply light (red) on the second or on the third time when I try to start. How should it work and is there a sensor somewhere..?

the sending unit is in the head, whether V8 or Six.

here's your 1963 schematic: temp switch is shown to the left of the ign coil.

Okei, it's there on THAT picture - I was thinking of the picture with meters. Still, I don't understand why it lights sometimes with just "power on". Maybe a bad sensor and/or a poor connection?
Can't remember seen that on any other cars. Does it actually work like telling You that Your engine is hot or is it more like a sensor to tell that You just burned Your seals..? Is there a certain degree of temperature when it should work?

it's commonly called an "Idiot" light as it works (light comes on) basically when it's too late... you've overheated...

the light will generally come on for a second when ignition is operated while the system sets... it should turn off pretty much immediately when engine is started.

definitely recommend an auxiliary "Temp" gauge showing degrees instead of a light that turns on ONCE you've overheated...

Very true. Aftermarket gauges are inexpensive and cheap insurance to protect your motor. In fact, gauges are so great, I can tell when my oil is low by the pressure gauge, which is good because I dont have a dipstick at the moment...Thats how much I trust my gauges.
