* Immediate Loss of Power: The engine will abruptly stop running. There will be no sputtering or gradual slowdown. It's an immediate, complete cessation of power.
* Loud Noise: Often, a seizing engine will produce a very loud knocking, banging, or grinding noise just before or at the moment of seizure. This sound is the result of metal-on-metal contact as components grind against each other.
* Resistance to Cranking: If you try to restart the engine, it will likely be impossible to crank it over. The starter motor might struggle, making a whining sound, or it might not even turn the engine at all due to the extreme resistance.
* Smoke (potentially): Depending on the severity and location of the seizure, you might see smoke coming from the engine compartment. This could be from burning oil or other materials.
* Damage to related components: The sudden stop and extreme force can damage other parts of the drivetrain, such as the transmission or even the driveshaft.
What causes an engine seizure?
Engine seizures are usually caused by a lack of lubrication (oil), leading to friction and metal-on-metal contact, which causes the engine parts to weld together. Other causes can include:
* Low oil level: Most common cause.
* Loss of oil pressure: Due to a faulty oil pump, clogged oil passages, or a hole in the engine block.
* Overheating: Extreme temperatures can cause parts to warp and seize.
* Foreign objects in the engine: Such as a broken connecting rod, a piece of debris, or even a bolt.
If your car's engine seizes, do not attempt to restart it. Towing is the only safe course of action. Attempting to restart a seized engine will likely cause catastrophic and expensive damage.
