When removing EGR upper tube assembly being
careful not to drop the silicone rubber seals in the
intake manifold. Clean gasket surfaces on the EGR
valve. Note that any loose dirt can lodge between the
pintle and the seat and cause valve leakage that will
give a rough idle and depressed manifold vacuum.
INSTALLATION
(1) inspect rubber silicone seals on intake manifold
end of EGR tube.
(2) Install upper tube into the intake manifold,
being careful that the silicone rubber seals are cor-
rectly installed and undamaged..
(3) Install new gasket between the EGR valve and
tube and install bolts.
(4) Tighten the EGR upper tube to intake manifold
plenum screws to 11 N·m (95 in. lbs.) torque.
(5) Tighten the EGR upper tube to EGR valve
bolts to 11 N·m (95 in. lbs.) torque.
(6) Install the throttle cable bracket to intake
manifold.
(7) Install air inlet tube and resonator.
(8) Connect negative battery cable.
EGR TUBE LOWER—2.7L
REMOVAL
(1) Disconnect negative battery cable.
(2) Remove air inlet tube and resonator and
bracket
(3) Remove EGR tube mounting screws at EGR
valve (Fig. 5).
(4) Remove EGR tube mounting screws at exhaust
manifold.
INSTALLATION
(1) Install new gasket between the EGR valve and
tube and loosely install bolts.
(2) Install new gasket between the exhaust mani-
fold and tube and loosely install bolts.
(3) Tighten the EGR tube to EGR valve bolts to 11
N·m (95 in. lbs.) torque.
(4) Tighten the EGR tube to exhaust manifold
bolts to 31 N·m (275 in. lbs.) torque.
(5) Install air inlet tube and resonator and
bracket.
(6) Connect negative battery cable.
EGR TUBE—3.2/3.5L
The EGR tube attaches to the bottom of the intake
manifold plenum beside the throttle body (Fig. 7).
REMOVAL
(1) Disconnect negative battery cable.
(2) Remove air inlet tube and resonator.
(3) Remove EGR tube mounting clips at intake
manifold plenum (Fig. 6).
(4) Loosen transmission to throttle body bracket
(Fig. 7). Remove 2 nuts and 1 bolt and remove
bracket off of studs.
(5) Remove EGR tube mounting screws at EGR
valve.
