Possible leaking head gasket. You can add a bottle of dye to the coolant, then look at the tail pipe with a black light. The dye will show up bright yellow after driving a few miles.

Thank you. I was afraid somebody was going to say that. I am going to take it in and have it looked at, but can you give me a ballpark for what that job might cost? It doesn't sound cheap.

A typical head gasket job could run $500.00 to $700.00. Your engine is not an "interference" engine. Those engines have valves and pistons that occupy the same space but at different times, . . . as long as the timing belt is installed correctly. Any problem with the belt breaking or jumping a few teeth, or incorrect installation after replacing head gaskets results in the need for a valve job which will add a whole bunch to the repair bill. Your engine uses a chain instead of a belt and it's not an interference engine.
