Hydrostatic Lock

When an engine is suspected of hydrostatic lock (regardless of what caused the problem), follow the steps below.

1. Disconnect and isolate the negative cable.
2. Inspect air cleaner, induction system, and intake manifold to ensure system is dry and clear of foreign material.
3. Place a shop towel around the fuel injectors to catch any fluid that may possibly be under pressure in the cylinder head. Remove the fuel injectors. Refer to INJECTOR(S), FUEL, REMOVAL AND INSTALLATION .
   CAUTION:

   DO NOT use the starter motor to rotate the crankshaft. Severe damage could occur.

4. With all injectors removed, rotate the crankshaft using the crankshaft.
5. Identify the fluid in the cylinders (coolant, fuel, oil, etc.).
6. Be sure all fluid has been removed from the cylinders.
7. Repair engine or components as necessary to prevent this problem from occurring again.
8. Squirt a small amount of engine oil into the cylinders to lubricate the walls. This will prevent damage on restart.
9. Install fuel injectors. Refer to INJECTOR(S), FUEL, REMOVAL AND INSTALLATION .
10. Drain the engine oil. Remove and discard the oil filter.
11. Install the drain plug and tighten to the proper torque specifications. Refer to TORQUE SPECIFICATIONS  .
12. Install a NEW  oil filter and tighten to the proper torque specifications. Refer to TORQUE SPECIFICATIONS  .
13. Fill engine crankcase with the specified amount and grade of oil. Refer to CAPACITIES AND RECOMMENDED FLUIDS, SPECIFICATIONS .
14. Connect the negative cable.
15. Start the engine, allow to warm, turn engine off and check for any leaks.
