INFORMATION
New and remanufactured replacement engine assemblies are NOT pre-filled with engine oil.
After replacing an engine with a new or remanufactured engine assembly, the engine oil level must
be verified as outlined in the procedure below first, before starting the engine for the first time.
If the new or remanufactured replacement engine is started to determine electronically if the engine is filled
with the appropriate amount of engine oil, damage to the replacement engine can occur immediately.
The engine may have some residual engine oil from assembly, but this is not enough engine oil to properly
lubricate the engine to measure the engine oil level electronically when it is started for the first time.
Furthermore, the electronic engine oil measurement is only operational when the engine is running at its full
operating temperature. Checking the engine oil without the engine running at operating temperature will lead
to an incorrect or incomplete measurement.
After replacing the engine or making engine repairs that require the replacement or removal of the following
components, you must perform a short oil pump and oil supply circuit priming procedure. Refer to the
appropriate section below.

Engine bearings
VANOS gears
Camshafts
Bed plate resealing
Engine oil pump
Engine oil filter housing
Cylinder head
Engine oil cooler
Anything that interrupts the engine oil supply circuit of the engine

PROCEDURE
Engine Replacement:
The following procedure applies to all engines equipped with an electronic engine oil level sensor, with or
without an engine oil dipstick.
This procedure is used when the high-pressure fuel system pressure is already depleted from complete
engine replacement.

11 02 20_ENGINE REPLACEMENT AND REPAIRS - OIL PUMP AND SUPPLY CIRCUIT PRIMING PROCEDURE

1. After installation of the replacement engine and before starting the engine for the first time, remove the
engine oil drain plug. Drain any residual engine oil from the crankcase.

2. Reinstall and torque the engine oil drain plug (with a new seal ring) per the applicable repair instruction.
3. Remove the oil filter housing cover and verify the oil filter is present. Reinstall the oil filter housing cover
and torque it to the proper specification noted in the applicable repair instruction.

4. Fill the engine with the proper type and amount of engine oil, as specified in the applicable repair
instruction.

5. Manually rotate the engine 2 revolutions in the clockwise direction with the appropriate wrench or a
ratchet with socket. Never rotate the engine counterclockwise.

6. Connect a battery charger to the vehicle.
7. Remove the electric fuel pump fuse. Refer to the applicable wiring diagram using the VIN of the vehicle
in ISTA.

8. Crank the engine for 10 seconds.
9. After 10 seconds have elapsed, stop the starter, and allow the starter to cool for 20 seconds.
10. Repeat steps 8 and 9 two additional times.
11. Reinstall the electric fuel pump fuse and start the engine. Verify proper engine operation.
12. After the engine has reached operating temperature, check the engine oil electronically or with the
dipstick, and top up the engine oil as needed.

Cylinder Head Replacement or Valvetrain Repairs:
This procedure is used when the cylinder head is removed and installed, or replaced. This also applies to
valvetrain repairs where the valvetrain is disassembled from the cylinder head. This would include-

Camshafts
Eccentric shafts
Intermediate levers
Roller drag levers
Valve springs
Valves

The following procedure applies to all engines equipped with an electronic engine oil level sensor, with or
without an engine oil dipstick.
This procedure is used when the high-pressure fuel system pressure is already depleted from complete
engine replacement.

1. If the engine oil was drained, torque the engine oil drain plug (with new seal ring per the applicable
repair instruction), ensure the proper type and amount of engine oil is used when refilling the engine.

2. If you are unsure, remove the oil filter housing cover and verify the oil filter is present. Reinstall the oil
filter housing cover and torque it to the proper specification noted in the applicable repair instruction.

3. Manually rotate the engine 2 revolutions in the clockwise direction with the appropriate wrench or a
ratchet with socket. Never rotate the engine counterclockwise.

4. Connect a battery charger to the vehicle.
5. Remove the electric fuel pump fuse. Refer to the applicable wiring diagram using the VIN number of the
vehicle in ISTA.

6. Crank the engine for 10 seconds.
7. After 10 seconds have elapsed, stop the starter, and allow the starter to cool for 20 seconds.
8. Repeat steps 6 and 7 two additional times.
9. Reinstall the electric fuel pump fuse and start the engine. Verify proper engine operation.
10. After the engine has reached operating temperature, check the engine oil electronically or with the
dipstick, and top up the engine oil as needed.

Engine Repairs:
This procedure is used when the engine oil supply circuit is interrupted during a repair. This applies to-

VANOS gears
Timing chain tensioner
Bed plate resealing
Engine oil pump
Engine oil filter housing
Engine oil cooler
Any engine repair that interrupts the engine oil supply circuit of the engine

This procedure is used when the high-pressure fuel system pressure may not be depleted after minor
engine repairs. The fuel injection system needs to be disabled by removing the fuel injector electrical
connectors.

1. If the engine oil was drained, torque the engine oil drain plug (with new seal ring per the applicable
repair instruction), ensure the proper type and amount of engine oil is used when refilling the engine.

2. If you are unsure, remove the oil filter housing cover and verify the oil filter is present. Reinstall the oil
filter housing cover and torque it to the proper specification noted in the applicable repair instruction.

3. Connect a battery charger to the vehicle.
4. Remove all fuel injector electrical connectors to disable fuel injection.
5. Crank the engine for 10 seconds.
6. After 10 seconds have elapsed, stop the starter, and allow the starter to cool for 20 seconds.
7. Repeat steps 5 and 6 two additional times.

8. Reinstall the fuel injector electrical connectors, reassemble the vehicle and verify proper engine
operation.

9. After the engine has reached operating temperature, check the engine oil electronically or with the
dipstick, and top up the engine oil as needed.
