² Drive shaft distress: See Driveshafts in Suspension,
Group 2.
² Any front end structural damage (after repair).
² Insulator replacement.
ENGINE MOUNT INSULATOR ADJUSTMENT
(1) Remove the load on the engine motor mounts by
carefully supporting the engine and transmission as-
sembly with a floor jack. (2) Loosen the right engine mount insulator vertical
fasteners, and 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 identifica-
tion and related assembly length measuring. (4) Tighten right engine mount insulator vertical
bolts to 68 N Im (50 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.
ENGINE ASSEMBLY
REMOVAL
(1) Disconnect battery.
(2) Scribe hood hinge outline on hood and remove
hood. (3) Drain cooling system.
(4) Remove hoses from radiator and engine.
(5) Remove radiator and fan assembly.
(6) Remove air cleaner and hoses.
(7) Remove air conditioning compressor mounting
bolts and set compressor aside, if equipped. (8) Remove power steering pump mounting bolts
and set pump aside (9) Remove oil filter.
(10) Disconnect fuel line, heater hose and acceler-
ator cable. (11) Disconnect all electrical connections and har-
nesses at throttle body and engine. (12) Manual Transmission
(a) Disconnect clutch cable.
(b) Remove transmission case lower cover.
(c) Disconnect exhaust pipe at manifold.
(d) Disconnect starter and lay aside.
(e) Install transmission holding fixture.
(13) Automatic Transmission
(a) Disconnect exhaust pipe at manifold.
(b) Disconnect starter and lay aside.
(c) Remove transmission case lower cover.
(d) Mark flex plate to torque converter.
(e) Remove screws holding torque converter to
flex plate.
(14) Attach C clamp on front bottom of torque con-
verter housing to prevent torque converter from com-
ing out. (15) Install transmission holding fixture.
(16) Remove right inner splash shield (Fig. 5).
(17) Remove ground strap.
(18) To lowerengine separate right engine
bracket from yoke bracket To raiseengine remove
long bolt through yoke and insulator. IF INSULA-
TOR TO RAIL SCREWS ARE TO BE REMOVED,
MARK INSULATOR POSITION ON SIDE RAIL TO
INSURE EXACT INSTALLATION (Fig. 4). (19) Remove transmission case to cylinder block
mounting screws.Fig. 5 Right Inner Splash Shield
