Question

How much does it cost to fix a seized engine?

 It will cost around $3000 to $5000 for a locked engine repair. However, if it is a completely damaged engine, it will require replacement and will cost you between $5000 and $10,000.

 If your engine is locked up, pull over to a safe location and get it fixed immediately. The signs of engine lock-up include failure to start (often with a clicking sound), unusual noises like knocking or grinding, overheating with smoke or steam, and issues with oil or coolant levels, which can all indicate internal distress. 

Your mechanic will be able to diagnose the issue and suggest a repair or engine replacement. Sometimes, the issues can be minor. For instance, insufficient oil or fluid levels or spark plug issues are minor issues that are usually caused when the engine is locked up.  

However, based on the extent of damage, it might need an engine replacement, and you might even be suggested to sell your car if there are chances of recurring troubles or if the repairs and locked motor replacement cost is costlier than the cost mentioned.
