• Check the oil level. Add approved engine
oil to the recommended level, if
necessary. Do not overfill.
1.3.11 Checking the Oil Level
Ensure that the vehicle is parked on level
ground before checking the oil level. Wait five
minutes after shutting off the engine and then
proceed with checking the oil.
CAUTION
DO NOT let the oil level fall below the marking
on the dipstick. DO NOT overfill so the level is
above the upper marking on the dipstick. This
could lead to excessive oil temperature and/or
poor crankcase breather performance. Add oil
through the oil filler pipe as required in order
to maintain level within the safe range.

1.4 POWER PLANT ASSEMBLY REMOVAL
To access the engine or engine-related
components, the vehicle power plant assembly
must be removed as a whole unit by means of a
slide-out cradle. The power plant assembly
includes the engine, transmission (including
retarder if so equipped), air compressor,
alternator and transmission oil cooler.
Remove the power plant assembly as follows:
CAUTION
Tag hoses and cables for identification before
disconnecting in order to facilitate reinstallation.
Plug all openings to prevent dirt from entering
the system.
NOTE
No parts within the EECU are serviceable. If
found defective, replace the EECU as a unit.
• First
1. Shut off the heater line shut-off valves.
2. Disconnect the battery or batteries from
the starting system by removing one or
both of the battery cables from each
battery system. With the electrical circuit
disrupted, accidental contact with the
starter button will not produce an engine
start.
WARNING
Due to the heavy load of the rear bumper
assembly, it must be adequately supported
before attempting to remove it.
3. Remove the rear bumper assembly
complete with hitch if applicable from the
vehicle. Refer to Section 18, BODY, under
"REAR BUMPER REMOVAL".
4. Using the quick-connect drain hose, drain
the engine cooling system. Refer to
Section 05, COOLING under "DRAINING
COOLING SYSTEM".
5. If applicable, disconnect the block heater
connector located near the EGR mixing
chamber.
• With Vehicle Raised
1. Using a vehicle lift or jack, raise vehicle to
access transmission fasteners and wire
harness.
2. Disconnect propeller shaft.
3. Partially remove L.H. side transmission
protective panel to access connectors.
4. On vehicles equipped with an automatic
transmission provided with a hydraulic
output retarder, disconnect steel-braided
airline from pressure regulator output. The
