Pulled out of the driveway this morning to a low coolant light. Puddle in driveway. Drove to autozone to get the proper coolant and noticed the little hose that goes from the coolant tank to top of motor was disconnected. I reconnected it and added coolant. Had to do it a few times as it was empty. Drove 40 miles to work with no issues. Could this be just a one time random thing or could something else be wrong? Just wondering if I may have hit it when I was doing plugs but that’s was a month ago.
