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)
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
coolant sensor replacement need it
I'm not positive about your car, or the dash setup, but generally a water light means your low on coolant. If you drive while low on coolant, you run the risk of overheating your engine. Obviously that's not a good thing.
Check your coolant level...
Either low coolant level or the engine is overheating.
Because the engine is probably too hot.
The blue light is the high-beam indicator. The only reason I can think of that it would be flashing is the headlight relay isn't latching into the high-beam position.
I Dnt know
possibly overheating or faulty sensors in cap lid!
Could be that the coolant level is a bit low and the flashing light is telling you this. The level will drop when the fluid is running thru the motor. When you turn the car off the level rises back to nominal level. Dan
Low coolant level.
