Aero 9-5, 2002 vintage. This Check Coolant message appears very
occasionally, said fluid was indeed checked out to be ok. A search on
previous incidents of this has shown me the odd concerned message - in
particular several threads on something I'd rather avoid but have it
now if it's going to be fixable on warranty: head gasket.

Is it possible the Saab pooter acts up or there's a duff intermittent
sensor? The message always pops up (if it's going to) at cold start,
never reappears if the ignition is turned off and on (this is not to
suppress it but a fact of the current lot of this car: short
journeys).

Any info welcome..

Is the coolant level going down? If it is then, funnily enough, you
have a coolant leak. The best way to find out if it's going past the
head gasket is to drop in to a dealer and get the system pressure
tested. (They didn't charge when I did that, but then they did get the
ensuing head gasket job...) There's plenty of other places it might be
leaking from though.

If the coolant level is constant, then try putting some extra coolant
in first. If that doesn't cure it, then you can find out whether it's
the float switch in the reservoir that's the problem by using the car
with the switch unplugged for a while (you may need to bridge the
contacts in the plug, depending on which sense the switch works in).

Cheers,

Colin.

Does the fluid level go down?
Not uncommon for the water pump seals to seep on this model. Usually
telltale signs visible in the area around the water pump. Good idea to have
the problem looked into before the warranty runs out whatever the source of
the leak...if there is a leak.

Thanks for the 2 answers - check water pump seals after checking
coolant level. Latter is ok, the pooter only whinges once per
fortnight or so as well. But I'll give it a good once-over on the
weekend and even if the coolant checks out I might as well get Brains
looked at while he's still under warranty (or he might fire the eject
seat one day).
