Coolant Level Indicator Lamp: Description and Operation
Description
DESCRIPTION
A coolant low indicator is standard equipment on instrument clusters of vehicles not equipped with the optional steering wheel buttons. However, on
vehicles not equipped with the optional diesel engine, this indicator is electronically disabled. This indicator is located above and to the right of the
speedometer needle hub. On vehicles equipped with the optional steering wheel buttons, this indicator is replaced by the display of an icon and textual
message in the cluster multi-function display.
The coolant low indicator consists of a stencil-like cutout of the International Control and Display Symbol icon for Low Engine Coolant in the opaque
layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. An
amber Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the indicator to appear in amber through the translucent
outer layer of the overlay when it is illuminated from behind by the LED, which is soldered onto the instrument cluster electronic circuit board.
The coolant low indicator is serviced as a unit with the instrument cluster.
