just like was said,coolant low or bad switch,or needs air bled from the line
coolant sensor replacement need it
Check your coolant level...
Either low coolant level or the engine is overheating.
The service engine soon light on an Oldsmobile Cutlass Supreme notifies the driver that it is time to change the oil. It is trigger around the 3,000 mile mark at regular intervals.
I Dnt know
flashing blue means you have an electrical issues with the coolant sensor. you probably have a bad sensor that needs replacing in the coolant bottle hope that helps Phil
change your thermostat.
Mine went nut. After I filled up the coolant reservoir, the D light stopped flashing. Good luck!!
its a dance party
if the coolant light is flashing red it means it's overheating (DO NOT DRIVE), check coolent level "if level is fine", it may be your thermastat. if coolent level is low check your coolent hoses. (allow engine to cool before checking)
Switch the ignition off and start the car again.The light will then stop flashing.
Could it be that you are just low on coolant?
