Here's why:
* Seizure means the engine components are stuck together. This could be due to lack of lubrication, excessive heat, or other mechanical failures. The pistons, connecting rods, and crankshaft are essentially locked together.
* The crankshaft bolt is designed to hold the crankshaft in place. It's not intended to be used for turning the engine over. Applying force to the bolt in this situation could damage the threads or the bolt itself.
Attempting to turn a seized engine by the crankshaft bolt can lead to serious damage, including:
* Stripping the bolt threads.
* Breaking the crankshaft.
* Further damaging other engine components.
Instead of trying to force the crankshaft, you should:
1. Investigate the cause of the seizure. This may involve removing the cylinder head and inspecting the pistons and other components.
2. Attempt to free the engine. This may require specialized tools and techniques, and it's best to consult a qualified mechanic.
3. Replace any damaged parts. Once the cause of the seizure is addressed, you'll need to repair or replace any components that have been damaged.
Remember, attempting to turn a seized engine by the crankshaft bolt can lead to further complications and costly repairs. It's always best to consult a professional mechanic for help.
