Are you sure you do not have the V6 engine? Because those engines are known for that happening.

You put you have a 2.0L engine which those cars only came with a 2.2 four cylinder engine or a 3.0 v6 engine. I have to know before I give you the most likely cause.

If you have oil in the coolant most likely you have your oil cooler leaking and doing that. You would have to remove it to know for sure and test it with compressed air submersed in water. But more them likely its the oil cooler. Common issue on those.
