What are the signs of engine seizure?

[BeauAnn]

Engine seizure precursors include rapid temperature rise and abnormal noises. The manifestations of engine seizure are as follows: Significant increase in engine noise: During engine seizure, the overheating and expansion of pistons cause intense friction with the cylinder block, resulting in abnormal engine noises. Vibration and black smoke emission: The engine vibration becomes very noticeable, and in severe cases, black smoke is emitted. The expansion of the piston inevitably hinders the piston movement. When the friction between the piston and cylinder increases, it causes severe engine vibration. Overheating of the radiator: Due to increased motion resistance, the pressure inside the engine cylinder becomes very high, which can easily lead to engine overheating.
