WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
DO NOT use the starter motor to rotate the crankshaft. Severe damage could occur.
When an engine is suspected of hydrostatic lock (regardless of what caused the problem), follow the steps below.
- Disconnect the negative cable(s) from the battery.
- Inspect air cleaner, induction system, and intake manifold to ensure system is dry and clear of foreign material.
- 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 .
- With all injectors removed, rotate the crankshaft using the crankshaft barring tool (PN 7471B).
- Identify the fluid in the cylinders (coolant, fuel, oil, etc.).
- Be sure all fluid has been removed from the cylinders.
- Repair engine or components as necessary to prevent this problem from occurring again.
- Squirt a small amount of engine oil into the cylinders to lubricate the walls. This will prevent damage on restart.
- Install fuel injectors. Refer to INJECTOR(S), Fuel, Installation .
- Drain engine oil. Remove and discard the oil filter. Refer to FILTER, Engine Oil, Removal, 6.7L .
- Install the drain plug. Tighten the plug to 50 N.m (37 ft. lbs.).
- Install a new oil filter. Refer to FILTER, Engine Oil, Installation, 6.7L .
- Fill engine crankcase with the specified amount and grade of oil. Refer to Capacities and Recommended Fluids, Specifications .
- Connect the negative cable(s) to the battery.
- Start the engine and check for any leaks.
