2001 9-5 antifreeze is disappearing??

Hey all!
I have a nice running 9-5, has the 2.3 turbo. Runs great. Has about 230,000 miles.
I have an issue with the coolant. I have to add coolant pretty regularly, probably to the tune of a gallon every 4 weeks or so. In that time frame, probably not putting 500-750 miles on it as it is my teen daughters car, and gets used in town more than anything. The car never overheats, never see white smoke from exhaust, never skips, oil is clean. But also, I can't seem to find a leak which has me confused. I am going to park it on ramps overnight with cardboard under it to see if I can find drips anywhere, it just has me scratching my head. The amount it uses should be easy to see leaking! I have a hard time thinking it is a head gasket as the car shows no sign of that aside from the coolant usage. But I could be wrong??
Anybody here have any suggestions of where to look? I'm wondering if it leaks more while it is running and is just evaporating from the heat? I don't ever see steam but you can sometimes get a whiff of coolant when engine is hot.

Do you have excess pressure in the coolant overflow tank? Pull the spark plugs and look in the cylinders and see if some seem clean? Possible head gasket or hose leak that shows up under pressure.

Check the coolant bypass valve its on the firewall behind the right side of the intake manifold as you are standing facing the engine. Typically it will only leak as you are driving so its a huge pita to find if you are unaware. Take it for a ride get it up to temp and turn the ac on to LOW drive a few min park it and chdck for wetness way down deep in back.. Do this a couple times to be sure you don't see anything.

You have high mileage- if you don't have a good service history on it and know it was doneit is probably in dire need of at minimum a headbolt retorque. If the bypass valve shows no signs of leakage this is probably your problem its just burning off showing no signs. Even if the valve does appear to be leaking retorque the headbolts regardless.

Great advice above. Also, if you know what it smells like to have coolant in your exhaust, sniff around there. It is "sweet" odor. If you do, still try the re torque first.

Yeah, I know the smell well. Worked on Diesel trucks my whole career. And had a few cars with headgasket issues over the years. This car shows no sign of coolant in exhaust. Or in the oil. I will check the bypass valve and it sounds like a good idea to re-torque head bolts. I have ZERO history in the car. We have had it for the last 3 or 4K miles. The engie work I did do, I replaced the spark plugs and the DIC. I also dropped the oil pan and cleaned the sump. Runs well, no skipping. Just this pesky coolant issue. But the engine is jammed in there so tight you can't easily see much so I will look for leaks cold, then hot as well. Sooner or later I will find it! I really appreciate everybody's input. This is the first Saab I have ever had so I am not familiar with them. A lot of times cars have some little quirk and you folks are helping me learn about them!
Thanks

I think I finally found my leak. Amazing it took this long. I have searched for it several times. Everything gets so hot under the hood that any trace of a leak burns off and it is never wet when I have looked. Took it for a drive today, got back and smelled coolant. Popped the hood, and found just at race of coolant still wet. Found that the coolant tube from the reservoir to the engine has a pinhole in it. Right next to the clamp where it connects to the engine. Must have been seeping for months and finally got just enough for me to see.

After a few days of use, the car is holding steady with coolant level. Apparently the hose I repaired was the culprit!
I guess the issue is that the engine compartment is so tight it is just hard to find small leaks. And to top it off the under hood temp is pretty high so coolant just burns off fast if it leaks out slow enough.
Luckily I found and fixed this one!

Nice, changing hoses and lines under the hood is a cheap form of insurance!!

Going on a couple weeks, still haven't added coolant. Luckily just some hoses! Probably would have found the leak sooner if it weren't for the stuff being packed in so tight under the hood! Love the car, hate working on it! Got lucky this time though, something cheap and fairly easy to fix.
