EXHAUST SYSTEM AND INTAKE MANIFOLD 11 -13
ENGINE EXHAUST MANIFOLD—V-10 ENGINE
Engine exhaust manifolds are made of high molyb­
denum ductile cast iron. A special ribbed design helps
control permanent dimensional changes during heat
cycles.
REMOVAL
(1) Disconnect the negative cable from the battery
(2) Raise and support the vehicle.
(3) Remove the bolts and nuts attaching the ex­
haust pipe to the engine exhaust manifold.
(4) Lower the vehicle.
(5) Remove the exhaust heat shields (Figs. 16 and
17).
(6) Right exhaust manifold—Remove the EGR tube
and gasket (Fig. 16). Discard the gasket.

INSPECTION
Inspect manifold for cracks.
Inspect mating surfaces of manifold for flatness
with a straight edge. Gasket surfaces must be flat
within 0.2 mm per 300 mm (0.008 inch per foot).
INSTALLATION
(1) Using a new gasket position the engine exhaust
manifold onto the cylinder head. Refer to Figs. 16
and 17 to install bolts and stud bolts in the proper
position. Tighten the bolts to 22 N-m (16 ft. lbs.)
torque.
(2) Right side exhaust manifold—Install the EGR
tube using a new gasket (Fig. 16). Tighten the tube
assembly nut to 34 N-m (25 ft. lbs.) torque. Tighten
the two EGR nuts to 20 N-m (175 in. lbs.) torque.
(3) Right exhaust manifold—Install the dipstick
bracket to the manifold.
(4) Position washers and exhaust heat shields onto
the manifold stud bolts (Figs. 16 and 17). Be sure the
tabs on the heat shields are hooked over the top of
the exhaust gasket. Install the nuts and tighten to 20
N-m (175 in. lbs.) torque.
(5) Raise and support the vehicle.
(6) Assemble exhaust pipe to manifold and secure
with bolts. Tighten the bolts to 34 N-m (25 ft. lbs.)
torque.
(7) Lower the vehicle.
(8) Connect the negative cable to the battery.
