My low coolant light flashes on and off then it will stay on.I have checked my coolant level it is good what could be the problem? 1999 Buick regal


Make sure you are checking the coolant level in the radiator as well as in the overflow tank. The sensor is located in the radiator, so if the level in the overflow tank is good, it could still be low in the radiator.

Low coolant sensor on a 1998 buick


The coolant sensor should be located near where the upper radiator hose is attached to the engine and has a wire connector on it with 2 wires. It's the only sensor near there. Then there's the sensor that'll be attached to your reservoir tank somewhere along the firewall

My low coolant light is flickering on and off. I flushed the system today. No other symptoms. no overheating or leaks. this is on a 1995 Buick Regal Custom V6.


It could be that the low coolant sensor is just dirty. You should be able to follow a wire to the top part of your radiator, to the sensor, or it might be in the overflow tank, take it out and clean it, and see if that will do it, if not, replace it.

Low Coolant light flashing on 1996 Buick Regal 3.8


The low coolant sensor should be located in the passenger side radiator tank, You need to take it out and clean the sludge off of it for it to work right. Or you can just unplug it and forget about it, the light will go out and it won't cause any problems.

Coolant fill procedure


NEVER open the radiator when the car (or any other engine) is running!! The radiator is part of the pressurized cooling system (under that cap is coolant at 15psi)

Correct way to check the coolant in the radiator, is wait until the engine is COLD, then remove the radiator cap and re-fill.
