I left my heat on during a car wash and now there's smoke coming off my radiator, can it be just steam?

It was nighttime so I couldn't tell if it was smoke or just steam. I left the car running for a while hoping it was just water that got in/on the radiator. Am I on the right track? Do I need a mechanic?

    More than likely it is just steam.You had no problems with seeing any steam before you decided to wash the car.So to be sure.After you have shut the car off for a while, and engine is totally cooled.Check the overflow canister in the engine compartment for coolant level.If no fluid, add to the recommended level.Use a mixture of 50/50 anti-freeze and water.If the canister is already full.You are fine.But I'm sure it was just steam.Run the vehicle again until totally warm and check level again.If still in doubt.Check with a local repair garage.

    More than likely it is just steam and you do not need a mechanic to watch the water turn to steam.

    Probably just steam! Wait for an hour or so for the water to dry, then check on it again, just to make sure.
