(7) Engine mount adjustment, Refer to Engine

Mount Insulator Adjustment of this section.

ENGINE MOUNT RUBBER INSULATORS

Insulator location on (right side) and transmission

bracket (left side) are adjustable to allow right/left
drive train adjustment in relation to drive shaft as-
sembly length.

Check and reposition right engine mount insulator

(left engine mount insulator is floating type and will
adjust automatically (Fig. 3). Adjust drive train posi-
tion, if required, for the following conditions:
• Drive shaft distress: See Driveshafts in Suspen-
sion, Group 2.
• Any front end structural damage (after repair).

• Insulator replacement.

ENGINE MOUNT INSULATOR ADJUSTMENT

(1) Remove the load on the engine motor mounts

by carefully supporting the engine and transmission
assembly with a floor jack.

(2) Loosen the right engine mount insulator yoke

screw and two turns on yoke nut, then loosen the
front engine mount bracket to front crossmember
screws and nuts.

Left engine mount insulator is sleeved over

shaft and long support bolt to provide lateral
movement adjustment with engine weight re-
moved or not.

(3) Pry the engine right or left as required to

achieve the proper drive shaft assembly length. See
Drive Shaft in Suspension Group 2 for driveshaft
identification and related assembly length measur-
ing.

(4) Tighten right engine mount insulator yoke nut

to 102 N

Im (75 ft. lbs.). Then tighten front engine

mount screws and nuts to 54 N

Im (40 ft. lbs.) and

center left engine mount insulator.

(5) Recheck drive shaft length.

release fuel pressure, disconnect fuel lines and accel-
erator cable.

(8) Remove air cleaner assembly.
(9) Hoist vehicle and drain engine oil.
(10) Remove air conditioning compressor mounting

bolts and set compressor aside.

(11) Disconnect exhaust pipe at manifold.
(12) Remove transmission inspection cover and

mark flex plate to torque converter position.

(13) Remove screws holding torque converter to

flex plate and attach C-clamp on bottom of converter
housing to prevent torque converter from coming out.

(14) Remove power steering pump mounting bolts

and set pump aside.

(15) Remove

two

lower

transmission

block

screws.

(16) Remove starter.
(17) Lower vehicles and disconnect vacuum lines

and ground strap.

(18) Install transmission holding fixture.
(19) Attach engine lifting hoist and support en-

gine.

(20) Remove upper transmission case to block

bolts.

(21) See Engine Mounting in (Fig. 2) and separate

mount/insulators as follows:

(a) Mark RIGHT insulator on right yoke and en-

gine plate supports. Remove insulator to rails
screws.

(b) Remove FRONT engine mount through bolt

and nut.

partment.

(2) Align engine mounts and install but do not

tighten until all mounting bolts have been installed.
Tighten bolts to torque specified in (Fig. 2).

(3) Install transmission case to cylinder block,

tighten bolts to 102 N

Im (75 ft. lbs.) torque.

(4) Remove engine hoist and transmission holding

fixture.

(5) Remove C clamp from torque converter hous-

ing. Align flex plate to torque converter and install
mounting screws. Tighten to 75 N

Im (55 ft. lbs.)

(6) Install transmission inspection cover.
(7) Connect exhaust system at manifold.
(8) Install starter.
(9) Install power steering pump and air condition-

ing compressor. For belt installation Refer to Acces-
sory Belt Drive in Cooling System Group 7.

(10) Lower vehicle and connect all vacuum lines.
(11) Connect all electrical connections including

ground strap.

(12) Connect fuel lines and accelerator cable.

(13) Install radiator and fan assembly. Connect fan

motor electrical lead. Install radiator hoses. Fill cool-
ing system. Refer to Cooling System Group 7 for fill-
ing procedure.

(14) Fill engine crankcase with proper oil to cor-

rect level.

(15) Install hood.
(16) Connect battery.
(17) Start engine and run until operating temper-

ature is reached.
