How to Fix a Locked Engine

There’s nothing worse than trying to start your car and realizing the engine won’t turn over. If you hear a clicking sound when you turn the key or the engine doesn’t make any noise at all, there’s a good chance the engine is locked up. This can be caused by a number of issues including low oil levels, overheating, or mechanical failure. However, don’t panic! There are a few things you can do to fix a locked engine.

Check the Oil

The first thing you should do is check the oil level. If the oil is low or dirty, it can cause the engine to lock up. If this is the case, simply add oil to the recommended level and try starting the car again. If the oil is clean and at the correct level, then there may be a more serious issue.

Remove the Spark Plugs

If the oil level is fine, the next step is to remove the spark plugs. This will make it easier to turn the engine over. Use a socket wrench to remove each spark plug, and then try turning the engine over again. If the engine turns over with the spark plugs removed, then the issue may be with the starter motor, not the engine itself.

Use a Breaker Bar

If the engine still won’t turn over, you can try using a breaker bar to manually turn the engine. A breaker bar is a long metal bar with a socket on the end that can be used to turn the engine over by hand. Insert the socket into the crankshaft pulley and try turning it clockwise. If the engine turns over, then the issue may be with the starter motor or the alternator.

Check the Battery

If the engine still won’t turn over after trying the above steps, then it may be a battery issue. A weak or dead battery can cause the engine to lock up. Check the battery terminals for corrosion, and use a multimeter to test the battery voltage. If the voltage is low, then the battery may need to be charged or replaced.

Call a Mechanic

If none of the above steps work, then it’s time to call a mechanic. A locked engine can be caused by a number of serious issues, including a seized piston or broken crankshaft. A mechanic will be able to diagnose the issue and recommend the best course of action.

Preventing a Locked Engine

The best way to fix a locked engine is to prevent it from happening in the first place. Regular maintenance, such as oil changes and tune-ups, can help keep your engine running smoothly. It’s also important to keep an eye on the engine temperature gauge and avoid driving with low oil levels. By taking care of your car, you can prevent costly repairs and keep your engine running smoothly for years to come.

Conclusion

A locked engine can be a frustrating and costly issue to deal with. However, by following the above steps, you can diagnose the issue and fix it yourself in some cases. If these steps don’t work, it’s important to call a mechanic to prevent further damage. By taking care of your car and performing regular maintenance, you can avoid a locked engine and keep your car running smoothly for years to come.
