Long story short, i broke down while driving because i started to smell smoke through the vents. Pulled over and told someone to start the car and the car started but the whole serpentine belt assembly was shaking and rattling. At first I was almost certain it was a loose pulley, maybe the tensioner or idle pulley, but I took it to a mechanic and it took almost 3 weeks for them to look at it so it was sitting in the cold for a while. They said the engine was seized, and they could only turn the crankshaft 1/4 a turn. I just don't understand how my engine seized so quick or if its even seized to start with. Any ideas? Thanks!!
