RIGHT MOUNT
REMOVAL
(1) Remove right engine mount bracket (Refer to 9
- ENGINE/ENGINE MOUNTING/ENGINE MOUNT
BRACKET - REMOVAL).
NOTE: The right engine mount attaching holes are
slightly oversize to compensate for manufacturing
tolerances. The mount has been set at the manufac-
turing plant for proper powertrain alignment. There-
fore, it is necessary to mark the position of the
mount before the attaching bolts are loosened.
(2) Using a permanent ink marker or equivalent,
mark the position of engine mount to the body frame
rail.
(3) Remove bolts attaching mount to body (Fig.
88).
(4) Remove mount between engine and body frame
rail.
INSTALLATION
(1) Position the mount into the original position on
body frame rail (Fig. 88).
NOTE: Engine mount must be installed in the origi-
nal position on body frame rail. If mount was not
marked or frame rail was replaced, perform the fol-
lowing procedure.

(2) Perform the following procedure if mount posi-
tion was not previously marked or the frame rail was
replaced:
• Insert the new mount loosely in frame rail.
• Align the four holes in the mount with the mat-
ing holes in the rail such that the holes are concen-
tric (frame rail holes centered in the mount holes).
• Using a permanent ink marker or equivalent,
mark the position of engine mount to the body frame
rail while maintaining mounting hole concentricity.
(3) Ensure the mount maintains originally marked
position and install mount bolts. Tighten bolts to 28
N·m (250 in. lbs.) (Fig. 88).
(4) Install right engine mount bracket (Refer to 9 -
ENGINE/ENGINE MOUNTING/ENGINE MOUNT
BRACKET - INSTALLATION).
(5) Remove the support from under engine.
LEFT MOUNT
REMOVAL
(1) Remove air cleaner assembly.
(2) Disconnect negative cable from battery.
(3) Remove bolts attaching the power distribution
center (PDC) bracket to left mount and battery tray
(Fig. 89).
(4) Support transaxle with a suitable jack.
(5) Remove mount to transaxle bolts (Fig. 90).
(6) Remove left mount bracket to body frame rail
fasteners (Fig. 90).
(7) Remove mount.
INSTALLATION
(1) Install engine mount bracket to body frame rail
and tighten fasteners to 28 N·m (250 in. lbs.) (Fig.
90).
(2) Position engine/transaxle for installation of
mount to transaxle bolts. Install and tighten bolts to
68 N·m (50 ft. lbs.) (Fig. 90).
(3) Remove jack from under transaxle.
(4) Install bolts attaching the power distribution
center (PDC) bracket to left mount and battery tray
(Fig. 89).
(5) Connect negative cable to battery.
(6) Install air cleaner assembly.

LUBRICATION
DESCRIPTION
The lubrication system is a full-flow filtration,
pressure feed type. The oil pump is incorporated into
the timing chain cover and driven by the crankshaft.
Oil pressure is controlled by a relief valve mounted
inside the oil pump housing (Fig. 91).
OPERATION
Engine oil is drawn up through the pickup tube
and is pressurized by the oil pump and routed
through the oil filter to the main oil gallery running
the length of the cylinder block. A diagonal hole in
each bulkhead feeds oil to each main bearing. Drilled
passages within the crankshaft route oil from the
main bearing journals to the connecting rod journals.
The main oil gallery also feeds oil pressure to the
timing chain tensioner. A vertical hole at the number
three main bearing area routes pressurized oil
through a restrictor up into the cylinder head. The
restrictor that is integral to the cylinder head gasket,
provides increased oil flow to the main gallery. Upper
engine lubrication is provided by one main feed to
the number three camshaft bearing cap. Oil is then
routed through the rocker shafts to the remaining
camshaft bearing caps and rocker arms/hydraulic
lash adjusters. Oil returning to the oil pan from the
pressurized components supplies lubrication to the
valve stems. The cylinder bores and wrist pins are
splash lubricated from directed slots on the connect-
ing rod thrust collar (Fig. 92).
