LUBRICATION
DESCRIPTION
The lubrication system is a full flow filtration pres-
sure feed type. The oil pump is mounted in the tim-
ing chain cover and is driven by the crankshaft
OPERATION
Oil from the oil pan is pumped by a internal gear
type oil pump directly coupled to the crankshaft. The
pressure is regulated by a relief valve located in the
timing chain cover. The oil is pumped through an oil
filter and feeds a main oil gallery. This oil gallery
feeds oil under pressure to the main and rod bear-
ings, camshaft bearings. Passages in the cylinder
block feed oil to the hydraulic lifters and rocker shaft
brackets which feeds the rocker arm pivots (Fig. 98).
DIAGNOSIS AND TESING - ENGINE OIL
PRESSURE
(1) Disconnect and remove oil pressure switch.
(Refer to 9 - ENGINE/LUBRICATION/OIL PRES-
SURE SENSOR/SWITCH - REMOVAL)
(2) Install Special Tools C-3292 Gauge with 8406
Adaptor (Fig. 99).
(3) Start engine and record oil pressure. Refer to
Oil Pressure in Engine Specifications for the correct
pressure. (Refer to 9 - ENGINE - SPECIFICATIONS)Fig. 97 Right Engine Mount

Refer to Hoisting and Jacking Recommendations.
(Refer to LUBRICATION & MAINTENANCE/HOIST-
ING - STANDARD PROCEDURE)
(3) Remove oil fill cap.
(4) Place a suitable drain pan under crankcase
drain (Fig. 100).
(5) Remove drain plug from crankcase (Fig. 100)
and allow oil to drain into pan. Inspect drain plug
threads for stretching or other damage. Replace
drain plug and gasket if damaged.(6) Remove oil filter. (Refer to 9 - ENGINE/LUBRI-
CATION/OIL FILTER - REMOVAL)
(7) Install and tighten drain plug in crankcase.
(8) Install new oil filter. (Refer to 9 - ENGINE/LU-
BRICATION/OIL FILTER - INSTALLATION)
(9) Lower vehicle and fill crankcase with specified
type and amount of engine oil. (Refer to LUBRICA-
TION & MAINTENANCE/FLUID TYPES -
DESCRIPTION)
(10) Install oil fill cap.
(11) Start engine and inspect for leaks.
(12) Stop engine and inspect oil level.
NOTE: Care should be exercised when disposing
used engine oil after it has been drained from a
vehicle engine. Refer to the WARNING listed above.
STANDARD PROCEDURES - ENGINE OIL LEVEL
CHECK
The best time to check engine oil level is after it
has sat overnight, or if the engine has been running,
allow the engine to be shut off for at least 5 minutes
before checking oil level.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
reading (Fig. 101). Add only when the level is at or
below the ADD mark.

OIL COOLER & LINES
DESCRIPTION
An engine oil cooler is used on 3.3/3.8L engines
(Heavy Duty Cooling Only) (Fig. 102). The cooler is a
coolant-to-oil type and mounted between the oil filter
and engine block.
OPERATION
Engine oil travels from the oil filter and into the
oil cooler. Engine oil then exits the cooler into the
main gallery. Engine coolant flows into the cooler
from the heater return tube and exits into the water
pump inlet.
REMOVAL
(1) Drain cooling system. (Refer to 7 - COOLING -
STANDARD PROCEDURE)
(2) Disconnect oil cooler inlet and outlet hoses
(Fig. 103).
(3) Remove oil filter.
(4) Remove oil cooler connector (Fig. 104).
(5) Remove oil cooler.
INSTALLATION
(1) Lubricate seal and position oil cooler to fitting
on oil filter adapter (Fig. 104).NOTE: Position the flat side of oil cooler parallel to
oil pan rail.
(2) Install oil cooler connector and tighten to 27
N´m (20 ft. lbs.) (Fig. 104).
