LEFT EXHAUST MANIFOLD
REMOVAL
(1) Disconnect negative cable for battery.
(2) Hoist vehicle.
(3) Disconnect exhaust pipe at manifold.
(4) Lower vehicle.
(5) Remove the front two exhaust heat shield
retaining fasteners. Raise vehicle and remove the
fasteners at rear of heat shield.
(6) Remove heat shield (Fig. 53).
(7) Lower vehicle and remove the upper exhaust
manifold retaining bolts (Fig. 53).
(8) Raise vehicle and remove the lower exhaust
manifold retaining bolts (Fig. 53).
(9) Remove exhaust manifold and gasket (Fig. 53).
Manifold is removed from below the engine compart-
ment.
INSTALLATION
(1) Install exhaust manifold and gasket from below
engine compartment.
(2) Install lower exhaust manifold fasteners (Fig.
53). DO NOT tighten until all fasteners are in place.
(3) Lower vehicle and install upper exhaust mani-
fold fasteners (Fig. 53). Tighten all manifold bolts
starting at center and working outward to 25 N·m
(18 ft. lbs.).
CAUTION: Over tightening heat shield fasteners,
may cause shield to distort and/or crack.
(4) Install exhaust manifold heat shield (Fig. 53).
Tighten fasteners to 8 N·m (72 in. lbs.), then loosen
45 degrees.
(5) Connect exhaust pipe to manifold.
(6) Connect negative cable to battery.
CYLINDER HEAD COVER
REMOVAL
LEFT SIDE COVER
(1) Disconnect negative cable from battery.
(2) Remove the resonator assemble and air inlet
hose.
(3) Disconnect injector connectors and un-clip the
injector harness.
(4) Route injector harness in front of cylinder head
cover.
(5) Disconnect the left side breather tube and
remove the breather tube.
(6) Remove the cylinder head cover mounting
bolts.
(7) Remove cylinder head cover and gasket.
NOTE: The gasket may be used again, provided no
cuts, tears, or deformation has occurred.
INSTALLATION
CAUTION: Do not use harsh cleaners to clean the
cylinder head covers. Severe damage to covers
may occur.
CAUTION: DO NOT allow other components includ-
ing the wire harness to rest on or against the cylin-
der head cover. Prolonged contact with other
objects may wear a hole in the engine cylinder head
cover.
(1) Clean cylinder head cover and both sealing sur-
faces. Inspect and replace gasket as necessary.
(2) Install cylinder head cover and hand start all
fasteners. Verify that all studs are in the correct loca-
tion shown in (Fig. 54).
(3) Tighten cylinder head cover bolts and double
ended studs to 12 N·m (105 in. lbs.).
(4) Install left side breather and connect breather
tube.
(5) Connect injector electrical connectors and injec-
tor harness retaining clips.
(6) Install the resonator and air inlet hose.
(7) Connect negative cable to battery.
REMOVAL
RIGHT SIDE COVER
(1) Disconnect battery negative cable.
(2) Remove air cleaner assembly, resonator assem-
bly and air inlet hose.
(3) Drain cooling system, below the level of the
heater hoses. Refer to COOLING SYSTEM.
(4) Remove accessory drive belt.
(5) Remove air conditioning compressor retaining
bolts and move compressor to the left.
(6) Remove heater hoses.
(7) Disconnect injector and ignition coil connectors.
(8) Disconnect and remove positive crankcase ven-
tilation (PCV) hose.
(9) Remove oil fill tube.
(10) Un-clip injector and ignition coil harness and
move away from cylinder head cover.
(11) Remove right rear breather tube and filter
assembly.
