Hello All,
In addition to the "Ice" light mentioned in another thread,
my car is in the habit of telling me that I have "Low Coolant"
when I do not. This is not as consistent as the "Ice" light,
but it happens fairly often.
Every time I have checked in the past, and that's probably
been at least on 10 different occasions, the expansion tank
atop the radiator has been full, whether the car was warm
or dead cold.
Today, I decided to do a precautionary check when shortly
after driving several miles and the car had warmed up some.
The cap on the expansion tank was more difficult than usual
to remove, and the tank was full, as usual.
I took the car out again for another test run of several
miles, running at highway speeds, and when I arrived home
and stopped in the driveway I noticed afterward that there
was a bright green puddle, and a trail from that into the
garage. When I began poking around underneath, there
was a relatively steady stream coming out of the overflow
hose from the expansion tank. This has never happened
(that I've noticed, and I think I would have) in the past year
and it concerns me.
There was absolutely no indication of overheating on
the gauge or via the "Engine Overheat" light.
Any insights into reasons that sudden overflow like
this might occur would be appreciated.
