2002 Saab 9-5 Turbo.
I was at a stop sign when the power steering suddenly went out and the engine started smoking. The temperature gauge was normal. I was about a minute from home so I turned around and drove it back home (possibly a bad idea).
The serpentine belt had basically completely crumbled to pieces, as well as the idler pulley. I've replaced both of those parts (power steering is restored) but the engine still smokes.
Blue lines show where the smoke is coming from. It seems to be white/light gray, and it starts smoking after about 10 seconds after turning the car on. I ran it for 1 minute and the amount of smoke stayed steady the whole minute.
I did a full oil and filter change - the oil looked to be at normal levels on the dip stick, but the drain pan feels lighter than it should so it might have been low. The oil was dirty but did not look milky.
I also checked the coolant but it didn't seem to be lower than usual. Possibly related, this is the same car that had a lot of water dripping from its exhaust (I taste tested and it seemed to be just water)
Any thoughts on the culprit or at least what to try next to diagnose it?
