2013 Chevy Malibu 2.5L LTZ (80k miles - original owner)
On occasion there is a small coolant leak under the car. Also, after driving the car there is a coolant odor in the engine bay. The hoses, radiator and fill tank all look normal.
Before this causes a major problem it would be best to have it looked at. Just guessing I would look at the water pump.
