I was sitting in my car after going to the grocery store and letting my car idle for a bit. I noticed smoke or steam vapor coming up from my hood. I lifted the hood to see smoke/vapor coming from the area between the driver side headlight and the radiator. The reservoir is full and no leaks or smell of antifreeze. From what I could see the radiator hoses looked ok. Any thoughts? Is it possible that I hit a puddle and water splashed into a hot radiator? Idk worried lol. It stopped after about five minutes.
