S80 Coolant Loss

Hey, I drive an S80 too, and this sounds familiar. Was the engine overheating, and were you losing a ton of coolant, or just a bit here and there?

Thank you. No overheating, but the coolant depletion occurs gradually, requiring periodic top-ups. How long did it take you to get a diagnosis?

Okay, mine wasn't overheating either, just a slow leak. I kept topping it off for a while, but it got worse. Finally took it to a shop. They found the problem pretty quick. Save yourself the headache and get it checked out by a professional!

I appreciate the advice; it confirms what I was thinking. I'll schedule an appointment. It was a cracked coolant reservoir. New one cost 52€, all fixed!
