My Bentley calls the lite "K28  Coolant Temp. Ind. Lite",(page 97.75) I
believe the owners manual calls it an overheat light.

I just went and tried it with the "Coolent Level control unit" (page 97.67
relay #3} removed. The warning light blinked on start then went out,(normal
ops), temp guage goes up as it warms up.

Does anyone really know?
