I have a 1992 Chevy Lumina. It has been having an intermittent problem with
the "Low Coolant" light on the dash. After driving the car for awhile (an
hour or more) and driving at highway speeds sometimes the light will come
on. The radiator is full and the overflow tank is full also. Once the
light comes on it will stay on until the car is shut down. After a few
minutes rest, when the car is restarted the light will usually be off again.
Has anyone experienced this problem and if so, what was the fix? Thanks in
advance for any help provided.
It has been doing it for over a year or so. It is completely random. I can
drive it all around the neighborhood on short trips and never see it. I
know that there is coolant in both the radiator and overflow tank so I just
kind of ignored it. I have had the cooling system flushed after it started
thinking that maybe it would clean up the sensor or something, but that
It usually seems to manifest itself after a highway drive for over an hour
or so when the engine is nice and warm.
Does the sensor possibly need to be changed?
Thanks for the reply.
