My wife has been driving 96 saab 9000 for last couple of weeks while
I've been away...
 I've noticed a coolant wet patch under car where she has been
parking... but also inside front footwells some coolant (and some
smell ). on mats ..
I refilled with about 1.5 litres of coolant...
Does this sound like the matrix? ... would that also dump coolant
underneath the car rather than just inside as there is definately more
under the car than inside?

Does it sound a serious (expensive?) leak((she has driven at least a
few 100 miles while this leak has been going on without overheating at
all- I suspect it 1.5 litres over a week or so)...  Should I try
adding some radiator seal - or just take to garage?

Only wet I can see under car is coming from rubber flap lower down at
back of engine compartment ... I though this was jsut the drain for
the grille below the windscreen... but cound collant leak into that?

thanks
AJ

Nah, get a new matrix installed, you will need sooner or later. Radiator
seal might clog up the cooling pathways.

Could be both the radiator and the heater core.  If it's just the latter, in
my experience there's no sign of wetted ground underneath the car at all.

There are two rubber flaps on the firewall. The upper, and larger one, is a
drain for the area below the windscreen, as you said.

The lower, and smaller one, is the evaporator drain. It's where the
condensate from the A/C unit should discharge. Since the A/C evap and the
heater core are essentially in the same housing, it would be logical to
conclude that a leaky heater core would result in coolant coming out of that
drain also. I'd go with the core replacement and fix it right; the stop-leak
stuff could cause more problems than it fixes.

Re: saab 9000 coolant loss




Both rubber spouts are for the same purpose, to drain the fish tank
(aquarium).  Water collect sin it from the sunroof (the front two
drains of the sunroof), from water dripiing down the windshield and
from the evaporator.  Frequently they are clogged by leaves.  If you
have a leaking heater core, coolant could come out of there too but
the more likely place is inside the cabin and you can smell it.
