Saab 95 sport combi wagon anti freeze

Anti freeze disappearing . When parked no noticeable drip age . Oil dip stick clean . No change in oil pan contents .

Either a leak you’re not seeing or a bad head gasket with it leaking into the cylinders and out the exhaust. Any smoke from the exhaust pipe?

I,llcheck thank you

We drive another car in summer use the Saab very little . A couple of short trips and warning light comes on .

Between the engine and firewall there is a water control valve. It is a GM devised part that usually goes bad. The leak seems to be mostly when running. Its in the center half way down, a PIA to get to. Check out the SaabSite for guidance. It may be listed under cooling hoses.
