Actually, it is both a temperature gauge and a level gauge. If the level
in the expansion tank falls, the two electrical contacts in the cap no
longer conduct through the coolant. When this happens, the temperature
light starts flashing. Interestingly, if the coolant mixture is wrong
enough that it no longer conducts sufficiently, this too can cause the
light to flash. And of course, if the temperature soars, the light flashes
... but who of us will admit to having ever seen the engine overheat to
this extent.Larry
