SAAB 900 1997 oil problem

Extreme high temps can break down oil pretty quick. Plus, if the inside of motor is kinda gunky the oil will pick up this pretty quick, also. The high temps probably helped a lot of gunk break loose, too. I would give it a new oil and filter change, new belt, antifreeze and definitly check for any coolant leaks as this sounds like you lost it by more than just boilover. Hope the high temps didn't do any bad damage like warp the head or blow the gasket. Keep a close eye in these areas after you get it going again. Good luck.

Serpentine belt broke on ur way home from the dealer? I'd take it right back to the dealer man, its not a lemon but a belt that borke on ur way home? Thats just too much,

in Toronto any dealer is obligated to check basic component such as serpentine belt before selling it to anyone. They might not change it if the condition is poor, but they will DEFINETLY change it when its so bad that it will snap on ur way home.
