No coolant loss indicator?

[hibshman25]

I just got done replacing a cooked apex motor for a guy. He punched a hole in his exchanger and overheated it. He claimed he never got a temp light warning on dash and this got me thinking.

If i understand correctly, if there is no coolant in the system the temp sensor is never going to get to a temperature hot enough to even trigger a warning light on the dash. Is this correct?

That's correct. The oil is cooled by the coolant also so a oil temperature sensor may help indicate a loss of coolant but I'm not sure if that would respond quick enough to prevent damage.

I run a coolant pressure sensor on my 360 have lost a few motors to coolant drops

when i got a hole in my exchanger and tried to nurse it home the light came on and i would shut it down for awhile and then run it again till the light came on again. eventualy the light stayed on constant so i got a tow the rest of the way. mine was an 07 gt. seems wierd that it did cause the temp sensor is in the coolant line but that was my experince.
