2004 Chevrolet Trailblazer engine problems

Our family was driving from columbus, ohio to louisville, ky. We had just crossed the state line going up I-75 hill near florance. When my wife said she seen smoke out her side mirror. I looked in rear view mirror and seen a little myself. I was in fast lane running speed limit, all gauges showed all was ok. I put turn signal on to begin finding a place to stop. Other cars near us began blowing horns and pointing at front right side of car. Once we got pulled off side of road, we turned vehicle off.

I was traveling on the highway when I herd a rattling sound coming from the engine, got off the highway and pull into a station. Call the tow company to tow it to my mechanic he said the water pump bearings broke and the fan stop turning since both are connected together, he said the engine might be damage possible due to overheating. There was no warning of over heating on the gage, water did not leak from the pump.
