04 Volvo XC90 coolant & sluggish engine
 

My volvo xc90 is leaking coolant but not onto ground and now my engine is running sluggish and check engine light came on.

Stop driving it and have it repaired.

Hmmm! Why didn't I think of that? Because I know that, maybe that's why. In the meantime while I was waiting for a response, I found it's a blown headgasket.
